The SRAM PressFit 30 Bottom Bracket is the replacement or upgrade cup-and-bearing set for anyone running a 30mm spindle SRAM or Truvativ crankset in a press-fit frame. The PF30 B2 is the wider PressFit 30 design and fits BB386 86.5, BBRight, PF 92, PF30 68, PF30 73, PF30 83, and PF30 83 Cannondale Ai bottom bracket shells , which covers the majority of press-fit road frames built around a 46mm inner-diameter shell. If your bearings are getting notchy or you're swapping in a new crankset, this is the direct SRAM replacement.

PressFit 30 combines elements from BB30 and PressFit bottom brackets, with an integrated seal pre-assembled into the cups to prolong bearing life, and the bearings themselves housed in nylon cups that press into the frame's bottom bracket shell . That nylon cup construction keeps weight down and lets the bearings sit slightly outboard of the shell, which is what makes it work across the wider PF386 and BBright shell widths without needing a different tool or interface. Gutterseal technology helps protect bearings from dirt and grime, and the steel cartridge bearings are smooth and long lasting .

Compatibility is where this bottom bracket earns its keep. It supports SRAM 30mm spindle cranksets including Road, Road Cannondale Ai, and Road Wide configurations, with chainline options of 45.0mm, 47.5mm, and 51.0mm covering standard road, Cannondale Ai, and road wide setups . If you're running an older Truvativ or SRAM 30mm spindle crank — anything from the BB30 GXP era through current DUB-adjacent 30mm cranksets — this cup set drops in without adapters.... Read More
