Yamaha PW TE Chainring

[SteveElsworth]

Hi, I have a emtb with a Yamaha PW TE motor and a worn out chainring. I can't find a replacement chainring anywhere. Its a direct mount chainring with a 28tooth spline mount (38T chainring). It looks a lot like a Bosch CX chainring, but don't know if it's the same. Anyone else solved this problem before. The bike is a R Raymon HardRay E 4.0 Electric Hardtail Mountain Bike Red

Hi,

I have the same bike and same problem. Paul's Cycles can order a direct replacement from Raymon, but I want other options, sizes etc.

Have you had any luck?

Sorry, no luck on other options. I bought a like for like replacement from Paul's Cycles. I can't believe there are no aftermarket alternatives, for what is a consumable part, but I was unable to find one.

I have been looking and I believe I have found a spider to fit it from FSA.

Good find. That's exactly what it needs, a spider that'll last forever, to convert the unique axle spline to a standard chainring size.

Think I'll order one tonight,

Hey Steve,
Do you happen to know what size socket I need for the chainring nut? I'm going to have to order one
