the existing "GXP" bearings on your Trek (Madone, Top Fuel Carbon,
Fuel EX Carbon, Remedy Carbon, Carbon Hardtail) or Gary Fisher (Superfly 100, Carbon
Road) bottom bracket. For replacing your existing bearings when running SRAM,
Bontrager, and TruVativ GXP cranksets. Includes two (2) replacement CH SERIES CERAMIC
HYBRID cartridge bearings and one (1) BB90/95® SPECIFIC
drive side silicone seal (Re-use your existing stainless steel end cap on
the non-drive side).
you are switching from a Shimano crank set to a "GXP"
style crank set (24mm drive side spindle/22mm non-drive
side spindle), this kit will not have all the hardware you need. To switch over to the new style, you will need a "conversion kit" which includes the
stainless steel non-drive side bearing cover.
The CH SERIES BEARINGS match the hardest Grade 5 ceramic balls with
the hardest available races. This means no soft stainless steel races. Our races are hardened chromium
steel, cryogenically treated and polished to make them the best possible match for the ceramic balls.
