Proper – Nonagon Sprocket ![]()
Proper’s “Nonagon” is a revised version of the already popular Magnalite sprocket, which has been adapted to fit socket drive or Thunderbolt cranks. It does come with adapters for 19mm and 21mm spindles but doesn’t fit non-socket drive Odyssey cranks. CNC’d from 5mm thick 7075 alloy, this looks to be a great addition to Proper’s range of sprockets.
RRP: £39.99
