Best on-line price for this BB.

Care is needed to ensure the plastic covers protecting the bearings does not come off when pushing the crank axle through the bottom bracket. I've had to buy two of these BBs, because when fitting the first one a plastic cover came off and when re-fitting it it crumpled. I've taken a cover off the second BB to replace the crumpled one. The low rating is due to the problems with installation. (I've installed many BB and I am a competent mechanic and this has been the first I've had to buy a second BB for spares.) Operationally it's a great BB and runs smooth.
