Need to modify to fit Yamaha PW-X

These will not fit on a Yamaha PW-X motor without modifying, on the right hand crank the back of the Isis Spline is too close to the spider Lockring, causing it to catch, damaging the crank - I took my Dremel with a Cut off disk, and trimmed both cranks down, rounded the sharp edge, and painted them - fits perfect now - shame they do not come from the factory with an extra 2-3mm of clearance needed.
But you can make them fit and they are great once they are modified.
5 Stars if they make them the correct size from new.

New 165 Aeffect

Bent a factory arm - Powerfly LT7 -on a tree stump. Local BS thought it would take 3 to 4 weeks to get a set in. Contacted Raceface directly, they were great. Ordered the shorter crankset, RaceFace were super fast and efficient in getting the cranks to me and minimizing my down time.
Love the crankset and really happy with RaceFace service !!

Happy with the cranks

I have a Giant Fathom e+ pro (2020) with the Giant SyncDrive Pro (Yamaha) and needed new cranks (ISIS). After searching the market and realizing my choices are limited at present, I opted to try these out even though they were optimized in design for a Bosch drive. Turns out they fit my bike just fine and I am happy with them.


I had to return them as they were the wrong ones
