Up for sale are these Kool Stop KS-D635K Shimano XTR 2011 Aero Kool Disc Pads.
Condition is new. I purchased these but sold my bike and no longer have a need for them. Looking into the sealed plastic packaging, there appears to be one spring clip. Guess that is a bonus!
Aero Kool pads are made with a forged aluminum cooling pinned backing plate and a high performance organic compound. The new pads greatly reduce heat build up in the braking system and provide superior, lasting brake power.
