We have Shimano and Campagnolo Electric Drivetrain and now it looks like SRAM is in the final stages of releasing theirs. This cross bike was spotted at the Illinois State Championships this past weekend and you can see the SRAM crank and a smaller wire at the rear derailleur that is typical to electric drivetrains.
Here is the write up on it:
SRAM’s long-rumored development of an electronic drivetrain went public Sunday when a rider in SRAM-branded kit raced on what is clearly a prototype shift-by-wire system at the Illinois cyclocross state championships.
SRAM is remaining tight-lipped about the groupset. “That’s a developmental product. I have no comment,” SRAM marketing manager Michael Zellmann told VeloNews.
With the public, if accidental, unveiling of an electronic group, SRAM joins competitors Shimano and Campagnolo in the steady move away from mechanical shifting.
Little is known about the group, aside from what can be seen in this photo. What is obvious is that an electric wire, not a cable, is actuating the rear derailleur. There is also something mounted to the rider’s stem, which we assume is some sort of battery.
The derailleur is has a short cage, indicating that the initial group will be targeted at the road and cyclocross markets. The shifters are matched with cable-actuated brakes, not the company’s hydraulic braking system.
The finish is rough, and the components are quite obviously in the prototype phase. We hope to learn more soon.
We will keep you posted as more information comes along from SRAM as well on this.
I also found a cool video and here is the link to Road Bike Party 2
And here is the bike that was used in the video and a write up of that as well:
While Martyn Ashton's brilliant Road Bike Party 2 video is currently going viral, BikeRadar decided to take a closer look at the bike used in the video, it's Colnago's C59 Disc.Martyn's Colnago C59 Disc is the world's first production disc-braked carbon fibre road racing bike, one of the fastest machines out there with a near identical frame to the one raced by France’s Thomas Voeckler in the Tour de France.
So, give this bike to a seriously fast rider and you'll get results, but give this bike to Martyn Ashton, Danny Macaskill or Chris Akrigg and you'll get results of an altogether different kind.
The bike has inherited a few subtle modifications and as a result would cost in the region of £15,000 / $24,500 to reproduce.
Despite the absolute brutality that this bike was subjected to, the only failures are said to have been punctures along with one brake line that was pulled out as a result of a crash.
Martyn took a standard set of Shimano XT flat pedals and modified them to minimise their profile to look more in keeping with a road bike
