What is the SRAM DUB English Bottom Bracket 83mm MTB for?

The SRAM DUB English Bottom Bracket 83mm is designed for downhill and freeride mountain bike frames with an 83mm English/BSA threaded shell. The wider 83mm shell accommodates the larger tire clearances and frame geometries common on gravity-oriented bikes. The DUB system's oversized spindle delivers the crankarm compatibility and durability that demanding MTB applications require.

The 83mm shell is specific to downhill and heavy-duty freeride frames. Confirm your frame uses this wider shell standard before ordering. Compatible with SRAM DUB cranksets designed for the 83mm shell. Not interchangeable with standard 68mm or 73mm shells.
