YINETTECH 4 STKS Fiets Crank Arm Bouten E-Bike M15 ISIS Crank Schroeven Compatibel met Bosch E-Bike Drives Compatibel met Brose E-Bike Drives

Essential spares for when the crank arm falls off the Bosch cx motor …. As they sometimes do!

Perfetti con autobloccante leggero

Surprised that my E-Bike crank nut had worked loose and fell out while out a long way from home causing my left crank arm and pedal to fall off ! It turns out Bosch Performance CX crank bolt sockets are not a left hand thread to prevent bolt loosening. I have used two of these to replace my right side bolt and the other to replace the lost bolt. I used removable thread locker on the bolts to stop them coming loose again. There is no indication on torque setting so I set it at the same as a wheel bolt of 12Nm. So far all working great and has solved a major problem trying to get original bolts which for some reason were not available. These got me riding again. I was going to use them as a temporary solution until I could obtain the originals but as they are still unavailable I now am leaving them installed as a permanent replacement. I carry the 2 extra boots with me in case of loss again but with the thread locker all tight and working perfectly. The price is excellent too. Definitely recommend.

no issues yet.fit perfectly and no rounding of socket after several removals

Excellent for my e bike crank arm came off bought these been good since i bought them great price great product
