AliExpress Bike Tools I Actually Use

The reviewer discusses two different designs of brake rotor and caliper alignment shims, one branded Rider Ace and the other Dmount. They explain how the tools are used to ensure perfect caliper alignment and eliminate brake rub.

AI-Summary

Pros

Makes aligning brake rotors and calipers perfectly easy
Ensures a slim bit of clearance on either side of the rotor to minimize brake rub
One of the designs (the smaller one) is noted to work with almost any set of calipers
A rim brake specific version is also available

Cons

One of the designs, described as the more sturdy and useful one, does not always work brilliantly in every set of rotors and calipers due to its size

Key Points

The tools slide onto the rotor, which is then rotated into the caliper; the brake lever is squeezed and the caliper bolts are tightened.
This process ensures correct clearance is set.
Two common shapes/sizes are shown: a sturdier one that can have fitment issues, and a smaller, more universal one.
