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.

Um...It's a bottom bracket..
Weaknesses:
Okay here we go, it creaks like hell and it snapped in half!
Bike Setup:
Giant Rainier
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

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.

Weaknesses:
Weak, non-replaceable components
Bike Setup:
Stock Std Giant XTC2, 2003
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.

Al diamond frame, deore alivio mix, sugino cranks (best bang for the buck!), RST fork, blah blah blah
Bottom Line:
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...

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.

from Salerno(near amalfi coast) Italy Date Reviewed: May 8, 2002
Duration Product Used:
Less than 1 month
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.
Similar Products Used:
SHIMANO LX square taper,it was flexy and the crank bolts were always coming loose in the longtime despite of locktight ,but i didn't manage to snap it in two as other bikers did.
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.

Favorite Trail:
Narrow Neck - Blue Mountains
Duration Product Used:
3 months
Price Paid:
$32.00
Purchased At:
Super Elliots - Adelaide
Strengths:
- New features of Deore now include hollow spindle AND Octalink.
Weaknesses:
- Mine only came with a nylon end cap.
Similar Products Used:
Dodgy Bros BB supplied with bike.
Bike Setup:
Deore crankset.
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.
