COONIUM BB86 BB92 Thread-Together Bottom Bracket for 41mm Press-Fit Shell, Creak-Free Ceramic Bearing BB for Shimano 24mm & SRAM GXP 22/24mm Crank, Road & MTB Bike (Not BB90/BB30/PF30)

• FITS 41mm PRESS-FIT SHELLS ONLY, CHECK BEFORE YOU BUY: For BB86 (86mm road）and BB92 (92mm MTB) frames with a 41mm inner-diameter shell. NOT compatible with Trek BB90/BB95 (37mm), BB30 (42mm), PF30/BB386EVO (46mm), OSBB, T47 or threaded BSA/Italian shells. Cranks: 24mm Shimano Hollowtech II or SRAM GXP 22/24mm only, not SRAM DUB, 30mm, square taper or ISIS
• HOW TO CHECK: Remove your old BB and measure the inside of the frame shell with a caliper. 41mm = this fits. 37mm = BB90/BB95, will not fit. 42mm or 46mm = BB30/PF30, see our other bottom brackets. Then check the shell width is 86–92mm. See the size guide in listing image.
• NO MORE CREAKING: Unlike standard press-fit BBs that rely on a tight press, the two halves screw into each other and hold the cups in line, which stops the creak and makes removal easy.
• CERAMIC BEARING: Sealed hybrid-ceramic bearings deliver higher speed performance and longer service life than even the best steel bearings
• IN THE BOX AND TOOL REQUIRED: 1 x thread-together bottom bracket and 1 x 22/24mm GXP adapter in the box. Installation needs a 16-notch, 44mm OD bottom bracket tool(not included)
• INTERNAL CABLE ROUTING, PLEASE READ: The two cups thread together through a center sleeve. If your brake or shift cables / hoses run loose through the BB shell, the sleeve may block them. Look inside your shell first. If cables pass through the middle, this BB may not fit your bike.
