The new Moulton Campagnolo compatible 11 speed sprocket set was on show at Cycle 2010. The press release is below:
The Moulton Bicycle Company is presenting their new eleven speed sprocket set to the public for the first time at Cycle 2010.
Designed to be fitted to the iconic, small-wheeled, Moulton bicycle, this new sprocket set is notable for its lightweight construction and a smallest sprocket with 10 teeth.
Tipping the scales at under 110g, this new sprocket set is CNC machined in three parts:
- The two smallest sprockets are hardened steel
- The next five sprockets are titanium
- The final four (largest) sprockets are ceramic-coated aluminium.
This Campagnolo-compatible sprocket set is available in a 10-28 ratio, with single-tooth jumps between the smaller sprockets: 10-11-12-13-14-15-16-18-21-24-28. Whilst giving high gearing for small wheels, this avoids the inefficiency inherent with 9-tooth sprockets, and large gear jumps that have been an unlikeable feature of some previous sprocket sets.
The new Moulton sprocket set is available only from The Moulton Bicycle Company and its distributors and dealers worldwide.
Moulton bicycles are exhibiting their range of British-built, small-wheeled, full suspension bicycles on stand D26 at the London Cycle Show, Earl's Court, on the 7th-10th October 2010 (7th - trade only).
Dr Alex Moulton patented the small-sprocket freewheel back in 1970 after devising new tooth profiles to ensure correct chain engagement (wrap), shifting and durability with sprockets as small as nine teeth. Many Moulton bicycles produced since then have featured sprockets with low tooth counts.
