FSA Yamaha PW-X Spider/Chain Blade Combination 38 Teeth

The original Yamaha e-bike spider/chainring with 38 teeth from FSA for e-mountain bikes with Yamaha PW-X mid-motor drives. The narrow/wide technology is what makes the spider/chainring so special.

What makes the Narrow/Wide technology so special?

The chainring is characterised by a narrow and wide tooth profile. The chain guide is integrated, so to speak, and the chain is prevented from jumping off. The Narrow/Wide chainrings make everyday life much easier for mountain bikers.

The bolt circle diameter is 4 x 104 mm. The 1 x 11 drive is also new. Compared to other drives, this variant saves weight, the speed of gear changes is faster and the fit of the chain is more secure.

As the spare part offered here is an original Yamaha / FSA chainring, it can be replaced without any problems.

You can find here the original Yamaha E-Bike Spider, without chainring, individually in our shop.

If you are unsure about the accuracy of fit, please contact us, we will be happy to help you.
