Rated 3.8 out of 5 by 33 reviewers.
Rated 3 out of 5 by just so you know, the spec for the sealing system on this hub changed recently M525 - double contact seal, (+ axle nuts prtotected by rubber covers) M525A - single point seal (no rubber boots over nuts) These really are different hubs! the picture to the right on my screen shows the M525-A but the description refers to the M525, so it is not clear to me which one is on offer here. My LBS ordered an M525 (from a different supplier) but received an M525-A which got built into my wheel. I would like to but another one as a spare but it aint gonna be easy ... 12 February 2013

Rated 4 out of 5 by Good budget hub For the price you can't better this hub. 19 April 2010
Rated 5 out of 5 by Can't go wrong for the money Cheap and long lasting if looked after. Spin nicely when adjusted right. Cones require a little finesse when servicing, maybe that's what people have trouble with? For the cash what more can you want? 11 November 2009
Rated 2 out of 5 by Not Great Like a few others here, my otherwise well specced hardtail came with a set of these. They started to feel very gritty after only 500 miles, most of which was on road. The seals are COMPLETELY non existant so be prepared to rebuild them every time you ride through mud or water. However tight I crank down the locknut, they still seem to loosen all by themselves. Even with the little mileage that they've seen, the cups are showing sings of major wear... I've started saving for Hopes... In short... good for people on a low budget wanting to do XC (in the dry!) or light dirt jumping, but not for people who do lots of miles, or extreme things with their bikes. COME ON SHIMANO! GIVE US CARTRIDGE BEARING HUBS! 13 September 2008

Description says M525 but picture shows M525A. If I buy which one will I be getting? They are very different hubs, M525A has poor sealing. Thanks.
