Product Description
American Classic’s ISIS bottom bracket is light because of the unique split ring design (patent applied). The new and improved
split ring and cups support the bearings
and keep them in place. The steel bottom bracket axle is designed to distribute the stress loads applied when riding. Replaceable stainless steel bearings are standard.
Also available with chrome steel bearings by special order for OE use only. Smooth ride feel. A proven design.

Strengths: LightWeaknesses: Self destructsBottom Line: I bought it for it's light weight, and replace-able bearings, but replace-able bearings are of no use when the installed bearing self destructs, and shears the bottom bracket fixing cup flange off in the shell. Expensive lesson.

Strengths: light weight (around 145g for road, 160g for mtb)Weaknesses: none yet. possibly breaings in the future but so far so good.Bottom Line: got it for the weight savings. the amclass isis bb is 50-100g lighter then most other isis bb's. my road set up weighs less then most higher end cranksets with integrated bb's at half the cost.

absolutely awful.then after about 6 months,the bearings came off whilst fitting.went straight in bin.most expensive truvative bb tool ever(came supplied with bb)
