RF makes Next-r's.... only in 165mm. I'd get a set if they came in 160mm. Next R e-MTB Crankarms

I got them because I didnt know RF made a set of Next I have next bars and wheels so it would have been a thing, ya know. LOL

Just thought of this the carbon arms I got from @ethirteen are 165mm like on the 9.9 and 9.8xt are its a good length in my opinion BUT the pedals have backed out everytime I ride. I put green locktite as its not permanent but it is becoming a thing.

I run Next R bars on all my bikes. I would have got Next R 36 wheels but couldn't find stock at the time. Went with Santa Cruz Reserve Carbons Instead. Wheels seem bulletproof.

Make sure you have the cranks on the right side.....there is a drive side and a non drive side....if they are back to front the pedals will back out.

its written on the crank under the protective block so not seen normally
