Worked well for a rebuild of an old AMF road bike. Item came as advertised and was easy to install. I no longer have the bike but it was a big improvement over the old single piece crank. Also nice that it opened up a whole world of options as far as crank arms and chainrings. I can't speak to how it compares with the BB adapters that allow the use of sealed units, but this was more than adequate.

This was a project that I had in mind for a year , to change my cranks from 1 piece to 2 piece ,,, after a mishap on the road I bent my right side crank my LBS told me it was a difficult and costly, so I did the job myself , after I looked at the reviews , I bought this BB replacement and new crank set, and it worked better then I expected , my bike is fairly new so my bearing races are in good condition , so I kept them in and just replaced the crank shaft and bearings , don't forget to use plenty OFgrease ,BB install was all of 20 mins . if you do the job yourself do your homework , take your measurements , Youtub it , get all the tools you'll need ahead of time , the removal of the old crank and install of the new BB and crank set , took about an hour . Will update performance as I go along , but this was so much easier then I excepted . before and after pictures .

Chose this over the truvativ conversion for my sons bottom bracket on his old Schwinn mountain bike when we chunked the one piece crank and went to a three piece crank on it. It is a quality item. Just be sure the bearing cups are fully seated in the bottom bracket and then take your time getting the final adjustment right when installing the bearings and spindle. Make sure you get the right length.

Much easier to install than the conversion kit that has four screws to hold it together and it's less expensive too, however this solution weighs about 2 ounces more than the other kit and bottom bracket combined. The plastic grease seals were busted in several pieces when it arrived so I will just need to clean and re-grease it more often. To be fair, it was delivered in January zero degree weather. Perhaps the plastic just got brittle due to the cold and rough handling in transit destroyed them. If you order parts during warm weather and don't go riding when it gets below freezing I suspect they are OK.

this bottom bracket set is cheaply made ' bearings grind in bearing cup's which rip away at the chrome plating which in turn wear out the bearings' sounds like gravel in b-b , I replaced the cup's & bearings within a week , but you get what you pay for , could use some spacers also but for the price its worth the it for the use of the spindle & other parts .

I purchased this item to go with a Shimano M191 front chainring set which is part of an overhaul project I am working on. I am upgrading and replacing parts on my old Huffy White Hawk to breathe new life into it. Also on the repair replace roster are the rims, tires, inner tubes, the freewheel, all shifting components and all brake components. When it is done it will be reborn as an 18 speed with SIS shifting, upgraded from the old, venerable and rusted 10 speed setup it currently has.While I would have given it five stars as everything fits the frame of this old bike, I was surprised to find that mine did not have fixing bolts as clearly shown in the picture. (Look at the very ends of the assembly). A trip to the local bike shop was not a big inconvenience. But just to be on the safe side, order a set of 8mm fixing bolts (or whatever is appropriate for your application) or the cranks will simply fall off. I recommend bringing the parts to the shop, as I did, to make sure everything matches up if this is your first time doing this. It saves time and frustration.
