Fitting SRAM Red Chainset

[BlueNGT]

I am fitting SRAM eTap and when the GXP Chainset is fitted the spindle is partly visible with a gap of about 5mm, or more, between the BB Cup outter edge and the left arm.

The bottom bracket is English Threaded

I currently have a Shimano Dura Ace BB fitted and understood this would be fine.

Are the bearing cups wider on a GXP bottom bracket than on a Shimano bottom bracket?

I cannot see why the SRAM Chainset does not tighten all the way to the cups. The spindle is the same length as the Shimano cranks (in fact the Shimano spindle is a few mm longer).

Any help very welcome!!!! ??

Seems you are not alone in finding out about this incompatibility

Get a GXP BB. Only around £20 and they last around 3 years on my mtb so must be fairly decent.

Add some of these to your DA bottom bracket and away you go.

I have a Hope HTII bottom bracket with these shims and a GXP Quarq Elsa R chainset. Works fine.
