Product Description

Large 22mm diameter hollow pipe billet axle reduces weight, increases strength and rigidity. An 8-spline joint between the bottom bracket axle and crank results in a more rigid, non-loosening crank assembly. Maintenance-free sealed cartridge keeps out dirt, mud, water and also allows bottom bracket to be installed quickly without adjustment.

Strengths:    Um...It's a bottom bracket..

Weaknesses:    Okay here we go, it creaks like hell and it snapped in half!

Bottom Line:   
Don't buy this if you don't like constant creaks and a total braekage. As I said, it creaks a lot and at random times, and mine broke in half when I was riding on flat ground! My warranty was up so I had to shell out 60 bucks for a new one and installation

Weaknesses:    outside thread looses easily causes the bb to crek, crek, crek, needs teflon to fix, see http://bontrager.proboards26.com/index.cgi?board=rims&action=display&num=1112775136

Bottom Line:   
Same problem with all deore bb users, my tip, use teflon or rugby, your problem will be solved, deore is very nice when you set it up correctly.

Strengths:    Cheap

Weaknesses:    Bearings easily damaged, as the other posted said, creek, creek, creek, creek! Noise irritating to the ears!

Bottom Line:   
In the DEore Gruppo, remove this one and change it to XT or XTR if you don't like headaches.

Bottom Line:   
i installed a new bb for the AIDS LifeCycle, rode this bb 600 miles from SF to LA, brought my bike home and within a week it was CREAKING! it still rolls but sounds like it's about to die. (yes, i changed the pedals just to be sure). i think 600 miles is pretty low for life expectancy on a bb.

Strengths:    Cheap

Weaknesses:    Weak, non-replaceable components

Bottom Line:   
Cracked the bearing race and it couldn't be replaced with another bearing, instead had to buy a new bb. Got Truvantiv instead. It's a shame decent quality bikes come with such poor parts, but I suppose if you bought top notch you pay top dollar.

No deterioration in 3 months of use. I think it'll last for some time. My lower grade BB-CSxx lasted me years... but that was Japan made, this UN40 is singaporean...

Strengths:    Great Strength for aggressive XC, (Splined version) Good stiffness, sealed bearings

Weaknesses:    Steel outers rust easily, not really that smooth.

Bottom Line:   
This is a good budget bottom braket. It is not really a race bb because it is not that smooth. the slpined interface adds a notice able amount of stiffness. Scince it is seald you dont have to worry about it getting clean and serviced.

Submitted by Vincenzo a Cross Country Rider from Salerno(near amalfi coast) Italy

Date Reviewed: May 8, 2002

Strengths:    Stiff,solid feeling,much better power transfer,smoother spinning under heavy cranking,improved crankarms/axle interface,crank bolts no more tend to loose.

Weaknesses:    Awful plastic cup on non-drive side(and SHIMANO is claiming on the web that the DEORE too specs an aluminium one)-the outer collar fitted around the axle on non-drive side looks not tightly fixed while the bb is still disassembled but once installed looks ok.

Bottom Line:   
I've switched to this from a stock LX/strongarm2 combo,because i felt it flexy and something "elastic",and i've founded it to be a big improvement:i've gained a much better power transfer,a smoother and more solid feeling,due to the combination of the hollowtech crankarms and oversized splined axle.The cranks/axle connection relies on a much extended surface;the splined zone ,along with a slightly tapered one behind it, and the larger diameter bolts make for a stable,strong fit between the parts.The bearings also spin free under load ,due to the extra stiff non-flexing axle,and the crank bolts no more get loose.So the bottom line is:the octalink standard is inherently superior to the older one,and the DEORE does probably the same good job as the more expensive LX/XT at a lower price.

Date Reviewed: March 23, 2002

Strengths:    - New features of Deore now include hollow spindle AND Octalink.

Weaknesses:    - Mine only came with a nylon end cap.

Bottom Line:   
First of all, I didn't have any troubles fitting this BB, but I only managed to get one with a nylon end cap, so it's not as durable as some higher end BBs.

Two great things are that the axle unit is a hollow cromoly design, so is strong, and it includes Octalink. This last feature makes the whole crankset that much stiffer.

Overall, ISIS and XTR style BBs may have a slight edge, but they are in a different price bracket, so the Deore BB certainly wins on value.
