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.

Date Reviewed: June 14, 2005 | | Favoriate Trail: | Waterdown Trails | | Duration Product Used: | 2 Years | | Strengths: | 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 | | Value Rating:Overall Rating: |

$45.00 | | Purchased At: | winning wheels | | Strengths: | inexpensive | | Weaknesses: | creak, creak, creak | | Similar Products Used: | shimano lx | | Bike Setup: | 1999 leadhopper + xtracycle, deore hollowtech cranks | | 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. | Value Rating: Overall Rating: |

Date Reviewed: August 4, 2004 | | Duration Product Used: | 2 Years | | Strengths: | Cheap | | 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. | | Value Rating:Overall Rating: |

$20.00 | | Purchased At: | Performance Bike | | Strengths: | Great Strength for aggressive XC, (Splined version) Good stiffness, sealed bearings | | Weaknesses: | Steel outers rust easily, not really that smooth. | | Similar Products Used: | no namers, | | Bike Setup: | Jamis hardtail | | 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. | Value Rating: Overall Rating: |

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. | | Bike Setup: | FSR XC comp disc 2000,MARZOCCHI MXR coil 80(real fork!),MRP X-link, DEORE octalink crankset,545 pedals,RITCHEY riserbars,DT onyx rear hub,HAYES HYDRAULICS(stock),OMEGABITE rear tyre(excellent),KENDA front tyre(very good). | | 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. | | Value Rating:Overall Rating: |

Date Reviewed: March 23, 2002 | | Favoriate 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. | | Value Rating:Overall Rating: |
