So many bike brands have their own house component lines, and so many of them generally are unremarkable, that we don’t usually spend a lot of time on them. But Commencal’s new Extra Cog Kit gives you everything you need to switch your 2×10 drivetrain into a proper narrow/wide 1×10 with wide range cassette.
The kit includes your choose of 30, 32 or 34 tooth narrow wide chainring with a 104bcd, plus a 42-tooth cassette cog to go on the back of your stock Shimano cassette, a 16-tooth one to replace the 15 and 17 and smooth the transition, and a longer B-screw to make sure your derailleur can handle the extra teeth at the top end.
Kit weight is claimed at 121g with a 32-tooth chainring, and it retails for just €99. hut the link above to order up, available for shipping throughout the EU.
