Overall Review:


This bottom bracket is compatible with the popular Race Face Cinch cranks. They are fairly popular with boutique brands and are a common offering on mid range all mountain bikes.  All bottom brackets eventually make noise and need cleaning.  This one needs more than the average.  Removal and installation requires a unique Race Face tool.  I would appreciate having more universal standards on that to reduce the number of tools you need when working on your own bike.  When the bottom bracket is brand new, it works really well and is quiet.  Unfortunately, it doesn't take long to need maintenance.


The seals and bearings are adequate initially, but they deteriorate quickly.  This causes noise, which will drive any biker nuts while pedaling.  With approximately the same number of miles and riding conditions I have had to replace this bottom bracket two times more often than the SRAM and Shimano bbs I have had before.  For the price I would expect a lot nicer and longer lasting product.
