Does anybody know the size of the Crank Spindle on stock Haro 8-spline spindles? They're 4130 Cromo with a Mid BB (sealed)
I know theres a differnece between the non-cromo ones and the cromo ones because, the bolt that tightens the arm onto the spindle on the end, is different. doe anyone know the size of the spindle so i can get new BB bearing because ive blown my ones.
thanks guys.

Either 19mm or 20mm,take you friends 19mm bearings if they got some and see if you spindle fits,if it doesnt its 20mm.

just take out the old bearings,look on the seal for the the bearing code,and email/go to/ring the nearest bearing manufacturer(sp?) with the code,they should be able to make a set for you
