Help with American standard BB, totally confused....
I’m re spraying my old jump bike and wanting to put new parts on it to freshen it up. Iv stripped the bike completely, re sprayed the base coat and Iv spent a good part of a week looking online for either parts or a whole new setup in regards to the bottom bracket.
Length on bottom bracket needed is 68mm,
width of bottom bracket is 56mm,(outer measurement not inner)
It’s a press fit frame.
The crank is 140mm long and has a front sprocket with 36T.
When looking Iv found you can get a press fit conversation that will change it from American standard to European standard but I have seen lost of crank sets that use enclosed Ball bearings so not sure if that’s what I need.
totally confused myself with it all and would really like some help with what I need to get going again.
as a new member I can’t post photos until Iv made 10 posts but if anyone can help Iv got lots of photos I can send on other means if possible.
thank you for reading and I really hope someone can help.
regards
martin
