Shimano Dura-Ace 9000

Its been a busy year for Shimano with the launch of new entry-level road groupsets and electronic Alfine hub gearing, not to mention three new mountain bike groups – but it looks like they may have left the best till last. Officially unveiled today is a new 11-speed version of their flagship Dura-Ace road groupset

Shimano have given their top mechanical group a ground-up reworking for 2013, not just an extra sprocket on the cassette. We had the chance to try it out for ourselves at Team Sky’s European service course base in Kortrijk, Belgium with team riders Alex Dowsett and Michael Barry, who were both instrumental in the development of the new group.Dura-Ace 9000 has already been used in competition at the Tour of Romandie, in its raw finish prototype stage.

Shimano announces 11-speed Alfine hub

Shimano has announced an 11 speed internal hub, primarily for upscale commuter and light touring bikes. The gearing range will be 409% (Alfine 8 speed is 307%). The hub runs in a oil bath similar to the Rohloff Speedhub, and should result in higher efficiency and longer service life. The price will be 300€, set for European release in September. If this hub proves strong enough, it may be a cheaper option to the Rohloff for no-derailleur off-road applications.
