Do I need wedges under my cleats?

Mix-and-match
Dear Lennard,
At one time I read in your column that you can change Campy 9-speed ergo shifters to 10-speed. Is this true and what are the details?
Guido Dear Guido,

Are ceramics that delicate?
Dear Lennard,
In your article on ceramic bearings in the recent VeloNews Buyers Guide I got the impression that these things were not only smooth but durable as well. As a result, I ordered a ceramic SRAM bottom bracket with the Red crankset on my new bike. To say the least, I was surprised when I read the SRAM maintenance instructions that came with it and saw the recommendation that one should disassemble and lube the bearings after every 100 hours of use and immediately after riding in the rain or wet.

What can I do about foot pain while cycling?

Tuesdays at VeloNews.com usually feature Lennard Zinn's "Technical Q&A"column, in which VeloNews' senior technical writer fields questionsfrom you, our readers. But this week, Boulder, Colorado, is playing hostto the first (and hopefully annual) CyclingScience Symposium and Expo, organized by the Serotta InternationalCycling Institute. Yup, it's a sort of bike geek Woodstock (albeit on a much smaller scale) and we knewexactly where we'd find our friend Lennard. For the next few daysZinn will be attending the seminar and, when he gets some time, even sendingus a few reports

Dear Lennard,I just installed a new Wippermann 10-spd chain on an otherwise Campy Record group. All the components are one year old. I'm trying to eliminate an annoying "tinging" that I'm getting when climbing hard out of the saddle or sprinting. No success with the "tinging" but I introduced a new problem ... the new chain jumps and skips and won't stay engaged in the larger cogs. Have I worn out the rear cogs? I'm now thinking that the "tinging" noise may be coming from the engagement of the chain with the chainrings (30-42-52 ); the old Campy chain engages the rear cogset okay, but perhaps

Getting a rider ready for the Tour de France, and the six- and seven-hour days in the saddle that come with it, requires a great deal of attention to detail. One detail that gets constant attention before and during the Tour involves the proper set up of new shoes and other equipment. These are often critical issues, because if a new shoe cleat is in even a slightly different position from where the old one was or a seat is a bit higher or lower or more forward or back from what the rider is used to, or the bar is positioned differently than before, it can be a big problem. Riding so hard

Funky disco drop-outDear Lennard;Last Saturday I installed a new Kelly rigid mountain bike fork on aGunnar Ruffian. Friends at the shop were a little miffed by the drop-outson the fork. Seems that they are, in a sense, forward/upward facing. Somephone calls yielded some vague information about problems with wheels runningdisc brakes coming loose from 'standard' forks. Can you comment on thisproblem? Can you tell me if you've seen Kelly's solution to the problem and,if so, what you think of the design?Judd Dear Judd;Well, you can just barely see that the dropouts face forward on thatKelly

Dear Lennard;I've seen many times when you recommend a pair of custom orthoticsto alleviate many common cycling issues. I plan on having a pair made formyself, but therein lies my question: when shopping around for a podiatrist(I've heard too many stories about people purchasing expensive orthotics,which then turned out to not be effective), what does an athlete need tospecifically ask or have done to maximize their monetary efficiency? I know that all custom orthotics will be different based on the individual'sneeds, but I'd like some advice from a man who's had effective orthoticsmade. Are

Dear Lennard,I have two bikes. Each bike has the same saddle and handlebar.I set up both bikes with the same measurement from saddle tip to bottombracket. Each bike has the same measurement from saddle tip to the centerof the stem/handlebar. On one bike the stem blocks the view of the fronthub. On the other the front hub falls in front of the stem. I measuredand their is a 1cm difference from bb to front hub between the bikes.Should I be concerned that I can see the front hub? Should I usea longer stem? Will this effect my handling?--Jeff Dear Jeff,Don’t sweat it. If you are happy with your

Dear readers;I am writing this from Italy, a few days after I had the chance to visit Milan for what has to be one of the world’s best bike shows. So if you don’t mind, I would like to start my weekly column with a look at fewof the treasures I spotted at Milan’s EICMA show. Conducted under gorgeous warm, sunny weather, the 61st EICMA bicycleand motorcycle show marks the official launch of a new road season. Italy is a great place for a show, and Milan in particular, because of the heritage of great design. As always, gorgeous Italian bicycles are in abundance, and the theme of ever more

Dear Lennard Zinn,I currently suffer from iliotibial band syndrome, which tends to affecthigher-mileage runners and cyclists. It causes a pain on the outside ofthe knee due to the repetitive motion of bending the knee. There is quitea bit of info on the problem with regard to runners but very little concerningcycling. I have gone to physical therapy and received a cortisone injectionfrom a knee specialist. Not much has helped. Have you heard of this affectingother riders? If so, do you know of any potential treatment options thatI have not tried? I can give up running but not cycling.

Dear Lennard ZinnI'm 50 and have arthritis in my left hip. I've been riding a pretty laid-back road bike for years (A LeMond with a 72.5 seat angle, seat all the way back)I do Yoga regularly, and that has helped, but my hips ache when I ride. I’m wondering if sitting further back might be "working" my hips more. The second part is that I have another frame I could have built up, but it's radically different: 73.5 seat, 40.5 stays. The front end is almost the same as the LeMond. Both bikes are steel, the other frame is 753. I'm 6'2" and weigh240. Some people have said the shorter bike would

Russel Bollig’s path to Lance Armstrong’s feet began with Tyler Hamilton,for whom he first built some custom orthotics in 1992. About four yearsago, Christian Vande Velde got some as well. They passed the word on toArmstrong, who was looking for an improved fit in his cycling shoes, andafter the 2001 season Bollig went to Austin, Texas, to fit the three-timeTour champion. While at Armstrong’s home, Bollig used resin-filled casting socks tomake casts of Armstrong’s feet and ankles. Then, back at his Podium Footwearshop in Boulder, Colorado, he made plaster duplicates of Armstrong’s feetfrom
