2003 haro f5 help please
I have a 2003 haro f5 and I need a new bottom bracket and spindle I know it's an American 20mm but I can't seen to find a spindle........also can I convert it to a different size that's more common
it is possible that something like this will work- https://www.danscomp.com/products-PA...de_BB_Kit.html
your spindle is 20mm but what matters is that the spline interface on the spindle fits your existing arms, which might work with that kit above.
however, those forged cranks are pretty awful. might be a good time to replace the crankset.
