Di2

Here's what I'm hoping cycling Santa will bring me ahead of the 2023 racing, riding, and reporting season.

It's only for e-bikes for now, but it has big implications for other bikes moving forward.

Twelve speed, semi-wireless shifting reaches a more affordable price point — though at a significant price premium over mechanical 105.

The death of Ultegra mechanical can only mean one thing.

Where theres a will, theres a way. When a World Tour rider wants sprinter shifters, he gets sprinter shifters.

It’s heavier than Force and Red, yes, but it arguably works even better and is way, way less expensive.

Shimano Dura-Ace wireless 12-speed drivetrains may be on the horizon, according to recently approved patents.

One reader asks about using a Campy crank on a Shimano drivetrain, while another reader inquires about mixing in a Wolftooth component.

When the Paramount was relaunched in 1998, the demand for the bike was so high, they were painted and shipped them as fast as they came in from Serrota.

Niels Albert is on a roll. The world cyclocross champion, a rider who became the discipline’s new prince last season, started his season with four victories in the lead-up to the first World Cup in Treviso, Italy, which he went on to win. Until now, Sven Nys has been regarded as the king of ’cross, but he’s had a very different start to his season. After a top-15 placing at the 2009 mountain bike world championships, his cyclocross season had a rocky start.

Ever since Shimano introduced the 7900 Di2 group at last fall’s Interbike show, it’s been surrounded by questions (as is any revolutionary new product). At first, the major question was simply Shimano’s wisdom in daring to venture down a path previously abandoned by Mavic and Campagnolo. Then the question was: will it pass the litmus test of adoption by professional riders and mechanics, who are historically traditional and resistant to change? Finally, will the parts ever actually become available at retail — and if so, will consumers buy?

Electric D-A: Why not a little step instead of a big leap? Dear Lennard, Great review of the new electronic Dura-Ace in this month’s VeloNews. I have to say there have been a lot of comments about the “why?” of electric and it was nice to finally read an article that included a good reason — shifting under load that can't be done with cable.

Popular Science has awarded Shimano's new Dura-Ace 7970 Di2 electric group a "Grand Award Winner" in the Recreation category of the magazine's “Best of What’s New 2008.” The group, available in January net year, was one of 100 technological innovations included in the December issue of the magazine, but swept the Recreation category to take the top prize as one of ten Grand Award Winners.

The first thing people might ask of Shimano’s Electric Di2 drivetrain is: What’s the weight penalty? There isn’t much. The group is roughly 60-grams lighter than the 7800 Dura-Ace group and only 60-grams heavier than the new 7900 group.

Shimano has formally announced plans to release Dura-Ace Di2, a new electronic shifting option for the all-new 7900 series Dura-Ace, in January. Composed of dual control shift/brake levers, front derailleur, rear derailleur, a wiring harness and battery pack, the new Dura-Ace Di2 7970 components integrate with components from the upcoming 7900 series Dura-Ace group, while adding only 68 grams.
