Rotor rings claim first road win
The elliptical chainring renaissance continued in Portugal a couple of weeks ago when Sergio Ribero of Team Barbot-Halicon scored the first professional road race win by a rider using Rotor's elliptical Q-rings. Ribero took first place in stage 1's uphill sprint finish, and followed it up three days later with second in stage 4 to finish second overall in the four-day race.
Developed as a lighter and less expensive alternative to Rotor's cam-action crank, Q-rings are claimed to help reduce the effects of the 'dead spot' in a rider's pedal stroke by effectively reducing the size of the chainring at that moment. This lowers the gear the rider is pushing and speeds the foot through the point at which little or no force can be applied to the pedal.
