- Press fit BB
I have just bought. anew to me frame ( Production Privee OKA) … it has. press fit BB.
Having done a little research on this (rubbish) concept , I am probably going Hope.
The frame states it’s a press fir 68/73 …
Hope offer a Press fit 68 or 73 … so which one is it?
I am intending to use some old Shimano crank sets with a single single ring …. the actually BB width( empty) is 92 mm, so what does the 68/73 refer to?
Or is this a really stupid question?Posted 3 months agowind-bagMember
The 68/73 refers to the shell width without the Shimano outboard bearings, add screw-in bearings and the overall width is 92mm…yup confusing. As you have press fit the overall B.B. width is, as you say 92mm (73mm shell + screw-in B.B.) so a crank with a 73mm axle length will fit.Posted 3 months agoLekuSubscriber
Wheels make some decent BBs. Using a 24mm axle (Shimano) gives you a coupe of options.Posted 3 months ago
