Submitted by brent a Cross Country Rider from calgary, alberta, canada
Date Reviewed: July 12, 2005
Duration Product Used:2 Years
Price Paid: $25.00
Strengths:Works- an invisible component for two years of solid cross-country riding
Weaknesses:a bit heavy, not as pretty as raceface or truvative when you have it out of the bike and in your hand :-)
Similar Products Used:old XT BBs, truvativ gigapipe
Bike Setup:Specialized Epic Disk, mostly stock
Bottom Line:After reading all the disastrous reviews for other BBs that cost a lot more (and promised a lot more), I thought I had to weigh in for this model- I've used it hard for two years and have had no issues. I hate the Strongarm cranks Specialized put on this Epic and I am therefore looking to go to something more upmarket, but I will probably end up staying with this BB and shimano's octalink system.

Submitted by Billy a Cross Country Rider from Knoxville, TN
Date Reviewed: February 13, 2004
Duration Product Used:1 Year
Purchased At:Came stock on bike
Strengths:It spins. Octalink is a good interface; screw that square-taper stuff.
Bike Setup:Jamis Dakota XC
Bottom Line:I don't really have much to say. The best thing I can say about this BB is that it's in there, and I don't ever think about it. Never squeaks or sticks, there's no play at the spindle-crank interface, it just works. There are lighter BBs out there, but I'm hanging onto this one until it stops spinning.

Submitted by Max Cooper a Racer from Providence RISD
Date Reviewed: October 20, 2003
Favorite Trail:Big River
Duration Product Used:More than 3 years
Price Paid: $20.00
Purchased At:jenson
Strengths:Takes a lickin' doesn't creak much
Weaknesses:o.k. it creaks sometimes
Similar Products Used:Truvativ Hellshow
Bike Setup:1 speed wheelies
Bottom Line:So I bought the POS jamis and rode it for a week, stripped it and used the parts. The LX cranik and this BB withstood 3 years of serious abuse. I've since replaced teh BB with the same one and it kicks ass. I'm a roadie/sprinter who rides a single speed Sant Cruz . Lots o' torque, plus I've learned in spectatcular fashion how to drop Lincoln Woods rocks to flat and this BB is still alive. I think i killed the last one in the winter. Not it's fault so much. TRuvativ broke in ONE DAY! Put this one back on, BUY SHIMANO< EVIL EMPIRE GETS IT RIGHT just about every time
maybe it's heavy who really cares, take your derailers off

Favorite Trail:Flowing...
Duration Product Used:3 months
Purchased At:Jenson Usa
Strengths:Cheap. Its still working just fine. No noises or slop.
Weaknesses:None yet.
Similar Products Used:Other shimano's
Bike Setup:Lx cranks. One with a 51 and other 2 have UN 72's.
Bottom Line:How do you spend 50 words on a bottom bracket that works. Thats it. It continues to work. No noise and no slop yet. Its only been 3 months though. All my trail riding has been in the wet muddy season with this bottom bracket. I'm big and I torque hard. Its different then the UN-72 as you can see through(hollow) from one end of the crank to the other.
