Try the ISIS BBs that are marketed specifically for downhill/extreme abuse. Those will be the best built. I had the gigapipe team DH BB and it held up pretty well. Otherwise, you are correct that you are throwing away money. Isis was flawed from the start unfortunatly. The bearings were too small, and they couldn't compete with shimano's needle bearings and precision. The isis standard backfired big time due to this problem, and made the bigger-bearing external BBs necessary.dgangi said:My 2 year old NRS is on it's second Truvativ Gigapipe SL bottom bracket, and this one is starting to develop creaks and slop. The first lasted about a year and a half...and the second 6 months. I don't want to throw good money after bad and get another crappy Truvativ.
I did a little homework and found *nothing* positive about any of the ISIS bottom brackets. I was thinking about the FSA Platinum Pro, but it was panned in the review section on this board. Same with the Race Face ISIS stuff. And lots of people dumped on the Truvativ Gigapipe (which I can attest first hand).
So what's a boy to do? The crankset on my bike is a Truvativ Stylo Team and I love it. But it's an ISIS so I am restricted to getting another ISIS BB. I know the newer style external cup BB's are stronger and more durable, but I would rather not get all new cranks just to get a better BB.
FWIW - the square taper Race Face in my '97 Trek hardail is original and is still running smooth. Based on my experience with that BB I thought all BB's were a "set it and forget it" item. Apparently I am mistaken
