Just fitted some along with the rubber shield seal thing. They are 3 times as sealed as oem Shimano so SHOULD last well.
Any users out there?
Did mine back in 2008 and still running, bit of play now but has done all 3 fort william dh enduros and lots of dh racing and uplift days on the hardtail.
After fun with ISIS bb's then even more fun with shimano/racface/truvativ external bb's back in 07/08 i opted to rebuild the raceface cups, £20 for the bearings and £10 for the shop to fit them as the older cups are ment to be throwaway when the bearings are shagged. At the time the rebuild was £8 cheaper than a brandnew DH rated replacement BB.
I also smeared grease over the outer bearing shield, before sticking the extra enduro seal on top. Think it was nearly 18 months before i repacked the bearings with grease. So far longest lived BB i have had, slight play and a bit rough now but still going, another repack then ride until the play gets worse, tempted to just have it rebuilt again.
Most happy with mine.
Mine lasted about half as long as the original Deore bearings. Absolute s**t IME.
Can you expand on that
Not much. Deore BBs aren't particularily durable but the enduro bearings were even worse, went gritty very quickly. I assume bad sealing. But not much more to say than that really other than that a brand new XT BB just cost me £12.90 so I won't be wasting money on Enduro again.
I like them.
I do have a question though; the rubber shield/seal thing - which way round does it go? Last set I fitted with the writing on the outside but now I think the silver metal bit should have actually been on the outside (against the crank arm).
I get about 12 months from an xt BB and changed to Enduro. It lasted 3 months in the same conditions. Back to xt for me.
Usually the bearing seals have the metal side nearest the bearings and the rubber side out. Thats what I did anyway.
