Hey I have a hutch rattlesnake frame that I was given and it needs a new bottom bracket (bearings) and I was wondering what size I would need ? I can't find anywhere online about the size so I fingured I would ask.
They were on a bmx bike, but that's all I really know ..
Are they 48 spline or do they have pinch bolts and an 8 spline spindle? If they're an 8 spline spindle than they are 19mm. If they are stock cranks or low end ones then they are 19mm also. Only higher end aftermarket cranks are offered with 22mm or 24mm spindles. If you post a pic of them I can tell you what size they are.
