Pads: Heatsink blues Time used:2/3 weeks Rim used:ronnie 24" Grind: medium Ceraminc: No Brake used:Oil bleed Magura HS33 with heatsink booster and echo lever. What is your opinion of a working brake: good bite, good lock, with a little modulation. How do they compare to previous pads you have used: They work alright. Review: Well, I wacked them on with a new grind about 2 weeks ago, and they have worn down loads, not very impressed with these pads. Set them up correctly, haven't moved them since.
