Brake rotors

[Santapez]

Hitting rocks and falling off logs. Crashing at high speed..

Ah. I always fall on the drive side.

Doing what?

The aluminum is pretty thin from the looks of it, like foil. Just sandwiched between two steel.

Hmm, my Shimano rotors seem to have heavy-thick aluminum. I would say they're way beefier than the plain steel rotors. They're also way beefier than the aluminum carrier Avid rotors I have.
