Will a Shimano Ultegra BBR60 bottom bracket fit the Ribble Endurance SLR frame? I cant seem to find any technical information on the frame anywhere?
Bottom Bracket: Press Fit BB86.
A Shimano BBR60 is threaded:
SHIMANO ULTEGRA - Bottom Bracket - Threaded - HOLLOWTECH II - 68/70 mm shell width
So no, the BBR60 won't fit.
Something like a Wheels Manufacturing BB86/92 would fit, though.
And it won't start making noises after 4 km.
