clearance between the chainring and the frame. This enables greater optimization of the chainline for gearing and provides frame manufacturers more clearance for tire sizes in the rear end of the frame.

The spindle of the MTB Wide crankset is 6 millimeters wider than a crank with a 52-millimeter chainline, pushing both arms out 3 mm on either side. As the MTB Wide crankset uses the same chainring as non-wide cranks, this also moves the chainring out 3 mm on the driveside to achieve the 55mm chainline.

The 55mm chainline has been specifically chosen for our latest SRAM Eagle Transmission groupsets, allowing for superior alignment of the chain between the chainring and cassette. This design option has also been selected by frame manufacturers and will still apply to Eagle and Eagle AXS drivetrain. As a result, all bikes fitted with UDH and compatible with SRAM Eagle Transmission require an SRAM DUB MTB Wide crankset to deliver a 55 chainline. SRAM Eagle Transmission cranks (T-Type) are required to work with SRAM Eagle Transmission.
