Used Between the Non-Drive Side Crank Arm and Bearing for SRAM/Bontrager GXP Cranks

Critical seal and spacer for for the non-drive side bearing when running GXP crank sets in TREK BB90 and BB95 bottom brackets ("net molded sockets"). The back side of the metal cover is packed with grease before it is placed over the non-drive side bearing.

NOTE: Many of our RWC Trek BB90/95 bearing kits include a special seal that takes the place of this metal bearing cover. That is our recommendation, but we have made this part availavle for those who prefer the "OE" design.
