Review on ๐Ÿ”„ SHIMANO Centerlock to 6-Bolt Rotor Adapter Black - Efficient Conversion for Any Size by Bomba Ton

Revainrating 4 out of 5

It is impossible to tighten according to the manufacturer's instructions without breaking.

Purchased to fit some Avid brake discs. The rotors are rated at 55 in-lb on 6 bolts, but this adapter comes with non-replaceable T10 M5 x 10mm extra thin bolts which are much weaker than regular T25 rotor bolts. T10 can only be tightened with a maximum torque of 3.8 Nm (34 in-lb), which is almost 40% less. Also, you can't use standard T25 bolts because the Shimano locking ring won't engage the hub's threads without extra-thin bolts. .After one of the bolts gave out (broke) when tightened to 55 in-lbs, I decided it would be best to use another brand that didn't require bolts (e.g. DT Swiss).

Pros
  • Hands-free operation
Cons
  • Clarity
