Hi
Just wonder whether anyone can give me any feedback on their experiences with these and whether they are worth the investment?
Also would i be able to run a standard inner ring with this as the big ring(on a sram rival chainset)?http://www.trainsharpcyclecoaching.co.uk/srm/Standard-130-BCD-Single-Ring.html
Cheers
Kurt :)
