Flyer SRAM E-bike Crankset EX1 ISIS – Black

The original SRAM EX1 cranks for Bosch, Brose & Yamaha drivetrains, with ISIS crank mount, are, like all products of the EX1 series, specially developed for E-MTBs and their high torques. Made of robust aluminium, they withstand even the toughest off-road use.

The SRAM components from the EX1 series are compatible with ISIS bottom brackets from:

• Bosch
• Yamaha
• Brose

Note: The chainring and end cap are not included in the scope of delivery.

Since the cranks we offer are original parts, you can easily change them if you want to change the crank length or if the crank arms are defective, for example.

What is SRAM EX1?

EX1 from SRAM is the first gear system developed specifically for e-mountain bikes. The EX1 components have been worked out as the perfect complement to the drive system of your e-bike and are tuned for the higher loads in operation. Smoother running, intuitive and safe shifting, longer battery life and more resistance to wear and tear are the result of this work.

Note: Please compare the illustration with the crank installed on your electric bike. If you are unsure about the fit, we will be happy to help you.
