    Decent workhorse

    This is the 3rd one of these I've had in 5 years. I my MTB all year round in all weathers. Daily on the road / canal towpath, for the commute, & several times a week off road. Although they claim to be "sealed" the seals can be removed & regreased relatively easily. For the money you can't really go wrong. Appulsorse.

    Top value bottom bracket.

    I bought this item to replace the stock bottom bracket on my mtb. The build quality is first class and this bottom brackets are pretty much bomb proof. Took 10 minutes to install with basic tools. There are newer and lighter bottom bracket systems out there but for cost, ease of use and dependability, there's no need to upgrade my chainset until I'm ready to replace my groupset.
