A friend has a gravel bike with a 68mm wide BB shell. Its threaded for BB. It has a GXP BB in and no spacers, and in is a SRAM Rival chainset, running 1x. I think its a 42t chainring.
She wanted a bling purple anodised Hope BB, so bought the threaded 68/73mm one, and a GXP adapter.
The Hope BB comes with a lovely machined alloy tube that sits between the two screw in cups. Its to keep the bearings out of water and cack that gets into the BB.
However the tube is really about 5mm to long and it wont allow the cups to screw flush into the frame. Its like it ‘must’ use spacers. With this tube, and the tiny added width of the gxp adaptor, the crank spindle is too short to attach the other arm.
Whats going on/wrong? Has she ordered the wrong part? Is the centre tube too long. On Shimano BB, the centre tube can have a variety of lengths as the bearing cups screw together. This Hope one has solid machined shoulders that put a finite limit on its maximum insertion (minimum length).
Can anyone think whats gone wrong?
