I have E13 TRS+ cranks which are 30mm matched to a E13 XCX/XCX+ bottom bracket with the uprated TiNi bearings.
The bottom bracket was fitted in March and has only seen dry rides due to the weather, and one muddy ride at the weekend.
Came to the bike this Monday and the cranks didn’t want to turn with horrendous noise from the BB.
Im going to contact the distributors as I bought it direct.
From looking around these seem to be a possible option

And BETD are the UK distributors for Enduro bearings so will be making contact to look at options.
