🚲 Fouriers Front & Rear Bike Boost Hub Conversion: Enhance your Ride with 15mm x 100mm to 110mm & 12mm x 142mm to 148mm Adaptability! Review

Impossible to install - end caps fall out every time you have to remove the bike and put it in a rack. This part cost the same or even more than the others, so I adopted a better design.

Perfect fit for me, yes a bit of a hassle to keep track of the spacers when removing the wheel but this is the perfect solution until I they buy new wheels.

Works as advertised. Not something you want to use if you take your wheels off regularly. Installing axle spacers can be a bit tricky. But after installation it works fine.

The rear version is a single spacer. This means that the wheel is misaligned to one side and the disc brake is able to align, but the cassette is too close to the frame, making it impossible to access the lowest gear (the chain is binding).

Not suitable for my needs. I need 2pcs 3mm axle spacers to convert 150-157mm axle standards. It has a 6mm washer that doesn't allow enough clearance between the dropouts and the cassette. The picture is incomprehensible and not entirely correct.
