Super fast Shipping! Should have ordered a new bottom bracket tool as my old Park B/B tool would not tighten the adjustment side fully.

      Comments about Nashbar ISIS Bottom Bracket:

      I'm upgrading a new bike for my granddaughter. Good frame but carried junk BB and stamped steel crank. Nashbar sells a very nice replacement BB and crankset at a reasonable cost. Both are much lighter and have a nicer finish. (see MT2 crankset)

        Comments about Nashbar ISIS Bottom Bracket:

        I've only been on a couple of rides since installing this bottom bracket and crankset. I was suprized with the smooth and easy pedaling. I'll really wring it out when I get my new derailleur.
        By the way, I've never been disappointed with the quality or durabilty of any Nashbar branded product.

            Nice, smooth BB. Use Park Tool BBT-22C Bottom Bracket Tool (Item #PT-BBT22C) or equivalent. My older Park BBT-2 did not fit over the large diameter hollow axle of the ISIS BB.

            Looks good, need 108 for road triple!

              Comments about Nashbar ISIS Bottom Bracket:

              Reading other comments and the live chat with a Nashbar rep led me to order the 113mm for my road triple. Well, I installed it and my chainline's off by about 0.100" which translates to 5 mm (0.100" on both sides) too wide. 113mm minus 5mm equals 108mm, so it's back to the drawing board for me!

              Otherwise I'm happy with the BB, it is will packaged, installed easily and spins smoothly.

                Very easy to install and works very well with the Nashbar CR2 crankset. Its been around for 120 miles and one crit race. Can't go wrong so far.

                Comments about Nashbar ISIS Bottom Bracket:

                Snapped the spindle in the center and allowed the pedals to spin independently of each other. Luckily I was only a few miles from home and I could pedal with just my right leg. I never thought this part would fail like this.

                  Comments about Nashbar ISIS Bottom Bracket:

                  I think this BB has been on my Santa Cruz SL for seven or eight years, so it's time to debunk the theory that ISIS systems are fragile. I just purchased another one for a different bike, and it seems to be more beautifully manufactured than the old one. Hopefully ISIS will be in my future for a long time.
