America’s Tejay van Garderen slotted into the top 10 on Wednesday at the Tour de l’Avenir after sneaking into the day’s winning breakaway. Van Garderen was among 13 riders to attack early in the hilly, four-climb stage across the French Ardennes in the 166.5km fifth stage. Spanish rider Jonathan Castroviejo won out of the break and Van Garderen came across the line seventh with the same time. Overnight leader Julién Bérard retained his leader’s jersey he’s worn since stage 1 after finishing safely in the main pack, which crossed the line nine seconds in arrears.

Tyler Farrar (Garmin-Slipstream) finally got his stage win on Wednesday at the 2009 Vuelta a Espana. It was a desperately long sprint for the American, racing in his third grand tour of the year. And he had to fight his way back to the lead group to do it, having been dropped on the final climb of the day, the Cat. 2 Alto Campo de San Juan. But Farrar gutted it out to take his first victory in a grand tour, crossing just ahead of Philippe Gilbert (Silence-Lotto) and Marco Marcato (Vacansoleil).

Race leader Mark Cavendish (Columbia-HTC) rocketed past Cervélo's Thor Hushovd on Tuesday to win stage 2 of the 2009 Tour of Missouri. It was another chaotic finale as ProTour and domestic teams butted heads in Cape Girardeau, battling to set up their sprinters in the final miles of the 112.3-mile ride from St. Genevieve. No matter. Cav' simply attached himself to Hushovd's wheel when the Cervélo man made his dash for the line, then shot past for his second consecutive win in this year's tour. The Norwegian hung on for second with Saxo Bank's J.J. Haedo third.
Garmin-Slipstream is still waiting for that elusive individual grand tour stage victory, but no one can criticize the U.S.-registered team for a lack of trying. With second to Simon Gerrans in Tuesday’s 10th stage, Canadian Ryder Hesjedal once again put the argyle jersey at the sharp end of the action at the Vuelta a España. The squad won the team time trial at the 2008 Giro d’Italia in its grand tour debut, but has since come enticingly close to a major stage win at the grand tours in two seasons at the elite level of the sport.
It was a close call for America’s Peter Stetina, who crossed the line second in Tuesday’s fourth stage at the Tour de l’Avenir and bounced into the top 10 overall. Denmark’s Troels Vinther won with a late attack that included Stetina and another rider. Vinther sprung his winning move in the final kilometer, gapping Stetina to claim the win by seven seconds. The main pack roared across the line 11 seconds slower, with French rider Julién Bérard retaining the overall lead that he’s held since an opening stage breakaway.
Simon Gerrans (Cervélo TestTeam) wasn’t included in this year’s Tour de France, but he proved to his team that he can be counted on to win in big-time races. The Aussie played it smart to take a four-up sprint out of the day’s winning 19-man breakaway to win stage 10 of the Vuelta a España on Tuesday. The win gave Gerrans a victory in every grand tour (with stage wins in last year’s Tour and this year’s Giro d’Italia) and gave his Cervélo squad a stage victory in all three grand tours in its rookie season.
Longtime criterium stalwart Frank Travieso (Championship Porsche) scored the biggest victory of his career Monday in Marietta, Georgia, by winning the 2009 edition of the US 100K Classic. The Cuban-born rider leapt out of the slipstream of Team Type 1’s Aldo Ino Ilesic at the tail end of a blistering 90 kph downhill sprint just in time to come around the Slovenian and take his first NRC title. Jake Keough (Kelly Benefit Strategies), who still holds the lead in the USA CRITS Series, was third.
Mark Cavendish (Columbia-HTC) survived a chaotic finale to win stage 1 of the 2009 Tour of Missouri on Monday in St. Louis. Cavendish's train was derailed in the final kilometer, and a pair of crashes threw additional monkey wrenches into the works, but he managed to close the deal anyway, finishing ahead of J.J. Haedo (Saxo Bank) and Thor Hushovd (Cervélo TestTeam).
America’s Alex Howes was one of the main protagonists in Monday’s 189km third stage at the Tour de l’Avenir. Howes snuck into the day’s main breakaway, which built up a menacing lead and put pressure on the French team to work hard to neutralize the dangerous escape.
A heavy Spanish accent was back on the Vuelta a España in Monday’s wild and unpredictable seven-climb stage from Alcoy to Xorret de Catí. After a week of stages dominated by non-Spanish riders, Gustavo Cesar Veloso (Xacobeo-Galicia) found himself the sole survivor of a daylong breakaway that tore itself to shreds on the final obstacle, the Category 1 Alto Xorret de Cati at 185.6km. Veloso became the first Spanish winner so far in the 64th Vuelta, having just enough in the tank to fend off the fast-chasing GC favorites.
Messe Friedrichshafen is the name of the group of massive exposition halls in which Eurobike takes place. Each hall is about the size of an airplane hangar, and there are 14 of them, including a center courtyard and several side wings. It boggles the mind to see so many bicycles on display in one place. Each of the halls has a number and letter (e.g., A7) and each booth has a number. Finding individual booths can be hard, but fortunately most exhibitors are roughly grouped by the type of gear they are showing, country of origin or some other characteristic.
Another French rider won at the Tour de l’Avenir, taking a bunch sprint in Sunday’s second stage. Jean-Lou Paiani (France B) was first across the line in the 138km stage from Dreux to Tourville-la-Campagne, outkicking European U-23 champion Kris Boeckmans (Belgium). Compatriot Julien Bérard, winner of Saturday’s opener, retained the overall leader’s jersey in the nine-day race across France.
Damiano Cunego (Lampre) won stage 8 of the Vuelta a España on Sunday, a mountainous, six-hour slog that ended atop the fog-shrouded categoría especial Alto de Aitana. Cunego shot out of an elite group of contenders to overhaul David Moncoutie (Cofidis) in the final kilometer of the 204.7km stage. The Frenchman hung on to take second with Robert Gesink (Rabobank) third. It was a big boost for Cunego, who has been criticized in Italy for his inability to live up to his promising Giro d’Italia victory in 2004.
Fabian Cancellara (Saxo Bank) proved he’s on track to add another gold medal to his growing collection with another superb time trial victory Saturday in the rain in Valencia. With the world championships on home roads less than three weeks away, the big Swiss time machine slogged through a rain-slickened course to claim his second win in a week at the Vuelta a España and regain the golden race leader’s jersey.

Without a doubt, the cycling industry brings its “A” game to Eurobike in Freidrichshafen, Germany, each year. While the week-long Interbike show represents the American trade show scene, Eurobike elevates the entire game with larger booths, larger halls, and larger crowds that have no problem filling vast aisles. It's a bonanza for bike tech hounds sniffing out new and exotic stuff.
They wanted the win on home roads, but Dutch-backed Vacansoleil are still tickled pink to have a stage victory at the Vuelta a España from Slovenian ace Borut Bozic in Friday’s 175.8km wild ride into Xátiva in the sixth stage. With temperatures pushing 100F, the 28-year-old unleashed a long sprint to upset the favorites and give his underdog team a huge boost in its quest to earn an at-large bid to next year’s Tour de France, which, like this year’s Vuelta, also starts in Holland.
Australians Jared Graves and Caroline Buchanan claimed a golden double in the four-cross events at the UCI world mountain bike championships in Canberra, Australia Friday.

Graves and Buchanan won Australia's first medals of the championships after each went through the night session undefeated before holding firm in the medal round to claim gold at Stromlo Forest Park.
Eurobike 2009 is as big as ever. Occupying more than ten huge halls, the show dwarfs almost anything in the industry for size, scope, and attendance. Many European brands produce goods not even distributed in the United States, so for now we’ll focus on what looks good, what’s new, and what could be hot for 2010.

Reigning Olympic champion Samuel Sánchez says he doesn’t expect to, but still believes he can win the Vuelta a España. That’s how Sánchez assesses things after nearly a week of racing in the Vuelta, sitting 65th at 1:09 back. “Right now I don’t see myself winning, but I know that I am capable of doing it,” Sánchez said. “It’s the same thing as trying to finish in the top 10 at the Tour; it’s one thing to think but it’s altogether something else to actually do it.”
André Greipel (Columbia-HTC) made it look easy in Thursday’s 174km fifth stage at the Vuelta a España, winning his second consecutive stage and bouncing into the race leader’s golden jersey thanks to finish-line bonuses. Wearing the green points jersey, “André the Giant” came off Tom Boonen’s wheel with 100 meters to go at the end of frenetic final 10km to catapult into the double, with the stage win and leader’s jersey to assure plenty of podium time.
In terms of roadside spectators, the opening four stages of the 64th Vuelta a España through The Netherlands and Belgium were a huge success.. “Just like the Tour de France,” some of the riders said. But the interest in North America has been minimal, at best, even though the top U.S teams Columbia-HTC and Garmin-Slipstream are taking part.

Chris Horner was among the major victims of a horrible high-speed crash Tuesday as scores of riders crashed near the end of the rainy fourth stage at the Vuelta a España. The Astana captain hit the deck with dozens of riders in a pile-up caused by a narrow run through a rain-slickened traffic circle within the 3km-to-go banner. The team later announced that Horner had broken his left hand and would leave the Vuelta.
André Greipel doesn’t think there should be an asterisk next to his victory in Tuesday’s stage at the crash-marred finale at the Vuelta a España. Greipel was only one of six riders to make it past a horrible accident that wiped out nearly all of the major sprinters, including Tyler Farrar (Garmin-Slipstream) and Tom Boonen (Quick Step).
Columbia HTC's Andre Greipel scored a stage win Tuesday at the Vuelta a Espana, on long, rainy stage — 225.5km from Venlo, in the Netherlands, to Liege in Belgium. Greipel beat Belgian Wouter Weylandt (Quick Step) and his German Columbia teammates Bert Grabsch and Marcel Sieberg to the line just moments after more than 40 riders, including overall leader Fabian Cancellara of Switzerland, suffered a huge pile-up just 2.6km from the finish.[nid:97319]

Perhaps it’s no mistake that Greg Henderson’s biggest road win of his career comes in the Vuelta a España. Monday’s stage-3 sprint victory for the 32-year-old Henderson caps a breakthrough season that’s also included major victories on Spanish roads, at the Clásica de Almería, the Vuelta a Murcia and the Volta a Catalunya. Holland isn’t quite Spain, but it is still the Vuelta a España despite its popular start in Benelux.
Planet Energy’s Keven Lacombe emerged from a stacked field of sprinters to win Sunday’s Chris Thater Memorial, coming to the line ahead of Lucas Sebastian Haedo (Colavita-Sutter Home) and Yosvany Falcon (Champion Porsche). In Saturday's women's race, Team Tibco's Brooke Miller outsprinted Theresa Cliff_rayn (Verducci) and Tina Pic (Colavita-Sutter Home) for the win. The race was both a National Racing Calendar event and a round of the USA Crits series.
New Zealander Greg Henderson (Columbia-HTC) sprinted to his first grand-tour victory on Monday in stage 3 of the 2009 Vuelta a España. The former track racer proved the fastest in a furious finale, crossing ahead of Borut Bozic (Vacansoleil) and Oscar Freire (Rabobank). Going into the final tricky corner, Henderson had a couple of Quick Steps in front of him and teammate André Greipel on his wheel. The idea was to launch the big German to the line. But things didn't work out as planned.
George Hincapie (Columbia-HTC) rode through a wall of sound as he outsprinted Andrew Bajadali (Kelly Benefit Strategies) to win the road race Sunday at the USA Cycling Professional National Championships in his adopted hometown of Greenville, South Carolina.

Chris Horner cannot wait to get to the warmer climes of Spain. It’s not that the Astana captain doesn’t like bumping shoulders on the narrow, rainy roads of Holland, but he knows that the real battle won’t begin until the Vuelta a España transfers down to the Iberian peninsula next week. In the meantime, it’s about gritting the teeth and avoiding a costly mishap.
Gerald Ciolek (Milram) has been lurking on the edge of greatness ever since he came out of nowhere to beat Erik Zabel and claim the 2005 German national title as a 20-year-old neo-pro. After winning the 2006 U23 world title, Ciolek has patiently been collecting minor wins and close calls in bigger events. He finally got his just reward in Sunday’s second stage of the 2009 Vuelta a España, a pan-flat 203.7km ride from Assen to Emmen in the Netherlands.
If Saturday’s rowdy and enthusiastic welcome for the Vuelta a España is any indication, next year’s Giro and Tour starts should be off the charts. An estimated 40,000 fans braved wind, cold and rain to watch SuperFabio roar into the leader’s jersey at the Vuelta, so just imagine what it’s going to be like in Amsterdam, which hosts the Giro start in May, and Rotterdam, which has the Tour’s grand depart in July. Holland is playing host to all three grand tours and the Dutch fans seem up to the task of making the pro peloton feel welcome.
Dave Zabriskie (Garmin-Slipstream) reaffirmed his position atop the U.S. time trial field Saturday, as he won his fourth consecutive national championship by nearly one minute on a 20.7-mile course in Greenville, South Carolina. Zabriskie blazed the winding Greenville time trial course Saturday in a time of 39:37, 1:02 faster than his winning time on the same course in 2008.
When the stage has a clock sitting at the finish line and riders start one at a time, you can almost bet the house that Fabian Cancellara is going to be fastest across the line. The big Swiss time machine reaffirmed his prowess against the clock with an impressive ride on damp but not wet roads in front of 40,000 rowdy Dutch fans to jump start the 64th Vuelta a España and snag the leader’s jersey.
The 64th Vuelta a España clicks into gear Saturday on the Assen race track with one of its deepest and most competitive fields ever. Not only are riders racing the Vuelta to prepare for the world championships, but some of the biggest names are lining up with nothing less than all-out victory as their stated goals. With none of last year’s top-3 back to defend their podium spots, the 2009 Vuelta is wide open. A challenging course well-suited for aggressive attacks in the mountains will promise to keep things interesting all the way into the final week.
Chris Horner will finally get a crack at the GC in a grand tour when the Vuelta a España clicks into gear on Saturday in Holland. That’s according to Astana sport director Sean Yates, who said the team will let Horner give it a stab for the overall classification. “Horner has progressed a lot this year, but he hasn’t had a chance to show on his own what he can do in the GC because he’s always been working for others,” Yates said. “I think he’s very motivated for the Vuelta. First he has to avoid a crash and then it’s a question of following.”
Garmin-Slipstream's sprinter Tyler Farrar will be looking for stage wins at the Vuelta a Espana starting Saturday, and the team is sending a squad of all-rounders and sprinters to help him get his first grand tour stage win. Farrar is coming off a string of successes at the Tour de France and the Eneco Tour. Team CEO Jonathan Vaughters says he expects the success to continue.
As if the last two years hadn’t happened at all, Alexander Vinokourov is back at the Vuelta a España and back on the Astana team. Ignore that two-year racing ban for illegal blood transfusions and forget about the behind-the-scenes power struggle at Astana involving Johan Bruyneel, Vinokourov and the power cadre of Kazakh backers. At least that’s what Vinokourov wants everyone to do.
Just in time for fall, Fort Bicycles is rolling out some great deals on cyclocross frames. A Fort all-aluminum Cross.Max frame is now selling for $349, and the carbon-aluminum Cross.Max.SSC is just $549. Both are sold as frames only (no forks), but Fort does offer SRAM, Campy, or Shimano build kits as special order items.
Suspended rider Danilo Di Luca said Wednesday that he may have been the victim of a conspiracy after twice testing positive for banned blood booster CERA during this year's Giro d’Italia. Di Luca purportedly finished second in the Italian tour, which he won in 2007, but subsequently returned positive tests for the third-generation of EPO, called a Continuous Erythropoiesis Receptor Activator (CERA), on both May 22 and 28. Di Luca won two stages during the Giro and held the leader's pink jersey for eight days before eventually losing to Rabobank’s Denis Menchov by just 41 seconds.

Columbia-HTC's Edvald Boasson Hagen won the Eneco Tour on Tuesday after winning the final stage, a 13.1km individual time trial in Amsfoort, the Netherlands. The 22-year-old Norwegian finished ahead of France's Sylvain Chavanel in the overall standings after the Frenchman clocked the fourth fastest time in the time-trial in the seven stage ProTour race through Belgium and the Netherlands. American Tyler Farrar, second in the overall standings, withdrew ahead of the final stage, saying he hoped to rest up for this weekend's start of the Vuelta a España.
Australian Allan Davis will have the chance to make amends for missing the Tour de France in July after he was named in Quick Step's squad for the upcoming Vuelta a España. Davis, a sprinter, was Quick Step's “tenth man” for the Tour in July, but missed out on a place after teammate Tom Boonen was given 11th hour clearance to race despite having tested positive for cocaine, for the second time in his career, two months previously.

Ivan Basso is taking aim at nothing short of overall victory for the 64th Vuelta a España, which clicks into gear Saturday in Holland. The Italian said he’s better prepared for the Vuelta than the Giro d’Italia earlier this season, where he finished fifth overall. “I trained myself in the best way without any stress,” Basso said in a team statement. “The final victory is a concrete goal.”

Six-time national criterium champion Tina Pic (Colavita - Sutter Home) is ending her career with a bang as she outsprinted Tibco's Lauren Tamayo and Brooke Miller at the Marion Classic Two-Bridge NRC Criterium in Indiana on Sunday. It was a double-win weekend for Pic's team as Luis Amaran solo'd to a classic win in the men's race, holding off a late charge by OUCH-Maxxis' Karl Menzies.
Team Columbia-HTC believes powerful German sprinter André Greipel can help continue its impressive 2009 season once the Vuelta a España clicks into gear this Saturday. Mark Cavendish's stunning haul of six stage wins from this year's Tour de France took his tally to 10 in two participations, and was the highlight of a hugely successful season for the American outfit so far.
Alexander Vinokourov is now officially part of the Astana team and is set to ride the Vuelta a España. The back-room wrangling over the return of Vinokourov went down to the wire, but team officials reached an agreement Monday to ease the way for his return to the Kazakh-backed team. Astana team manager Johan Bruyneel and Rinus Wagtmans, the authorized representative for the Kazakh sponsors, hammered out an agreement Monday. Vinokourov will be immediately welcomed into the Astana team and has a contract to race through the 2010 season.
There won’t be a late-hour bid to include Michael Rasmussen in the 64th Vuelta a España. At least Rasmussen isn’t expecting one. “All I can say regarding the Vuelta is that the team did not register me in time and that Unipublic did not want to make an exception by letting me in,” Rasmussen told VeloNews via e-mail. “They did, though, make exceptions with three Lotto riders that were not on the preliminary start list. Anyways — no Vuelta.” Rasmussen did not disclose the name of the team.
