    Comments about Nashbar ISIS Bottom Bracket:

    While building a bike for a petite young lady, this seemed a no-brainer. It works as it should, is easy to install, has sealed bearings, and was insanely cheap with Nashbar's frequent offers. I only feel guilty that I didn't buy two when the recent special was on. It's always good to have spares in inventory.

    If you're a Clydesdale that regularly does big drops in the mud and the blood and the beer, this is likely not your BB. If you're a competition rider, it will probably not your ticket also, but I hope you know that

    We found a tiny 'lil flat spot in the bearings that will probably work out in the first ride.

    Good value? Heck yeah, particularly as a replacement for an older square-taper that you want to no longer think about. You don't need to go searching for a bearing press to install it. Buy two. I'm sick that I didn't.

    Comments about Nashbar ISIS Bottom Bracket:

    An easy to install product but be sure you tighten it down according to torque specs (both the BB and esp the crank arm) so the positioning of your original crank stays somewhat the same so that you have minimal adjustments to make for the front and rear derailleur. I did not torque esp the crank arm right at first and it was off to the point I was surprised the front derailleur positioning was way off. It works well for now and is quiet compared to the failing Truvative Gigapipe that was originally there. Just was not too crazy about this version since it does not seem as well sealed compared to the Gigapipe whose design looked like it would seal out the elements and grit better. For the price, it was decent and will do the job. Will see how long it lasts before it will need to be replaced. It now has only a few weeks worth of miles on it so I'd say close to 600 miles and still feels good.

        Comments about Nashbar ISIS Bottom Bracket:

        I replaced my old Nashbar ISIS bb that was on my road bike for a bit over a year with another Nashbar ISIS bb. I won't buy this again, as I don't think it is designed for the 220-230 pound rider. Smaller riders may find it as a solid choice.

          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.

              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)

                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.
