$30.00 | | Purchased At: | cambria | | Strengths: | inexpensive, easy install | | Weaknesses: | Cheap, poor bearings, poor sealing | | Similar Products Used: | shimano, raceface | | Bike Setup: | jamis dragon | | Bottom Line: | CRAP. after under 2 years of moderately hard riding in perfectly dry (dusty) the bearings COMPLETELY siezed up on me. No amount of degreasing/lube/prayer is gonna fix these bearings. I always thought the greaseguard system was flaky, this proves it. Perhaps if the bearings were replaced with quality sealed units, rather than the half sealed bearings necessitated by the grease guard system, this BB would be worth it. But as is, I would have better spent my money on a UN-72. | Value Rating: Overall Rating: |

Date Reviewed: October 19, 2000 | | Duration Product Used: | 1 Year | | Bottom Line: | The bottom bracket works. Grease bottom with cranks on. Smooth off extra grease with anything that will fit between crank and bottom bracket frame - grease packed in this area will protect bearings against water/dirt intrusion. If a quarter once or less of extra grease is a problem you ARE a weight weenie. Use locktight on the clean bolt threads when you install - torque to the correct tightness and forget. If you don't ride in wet Pacific N.W. type conditions you probably don't need this bottom bracket. Get a Race Face taperlock instead -- which is also a great bottom bracket. | | Value Rating:Overall Rating: |

$28.00 | | Purchased At: | Cambria | | Strengths: | Smooth. Trouble free. Easy installation. Versatile applications. Simple design, adjustable chainline. | | Weaknesses: | The Greaseguard system for the BB is somewhat useless | | Similar Products Used: | Shimano XT/LX. Raceface taperlock, Real | | Bike Setup: | 99 Jamis Dragon | | Bottom Line: | I found that the BB, with the greaseguard system filled to the max with grease, will actually make the BB unnecessarily heavier. I'm not a gram counter, but there is a LOT of excess grease just sitting in the cups and spindle not making the BB any stronger or smoother, just heavier.
To remedy this, I just made sure to pack the bearings to 100% capacity with Finishline grease (The Best!) before the installation and leave they system empty.
So far this has worked well. The BB spins VERY smoothly, considerably less drag than a shimano BB.
Though the bearings are only sealed once, it has effectively kept out the dirt and grit.Though I could take advantage of the greaseguard system, I opted to just overhaul it.
This brings me to my next point. The entire BB is vey, very simnple. Just an axle,2 bearings,cups, spacer, and a couple of spacers. Pulling it apart is painless with a standard BB tool. But it is possible to stress the bearings in reassembly if you don't know what you are doing, leading to premature bearing wear. In this case, you can easily buy new cartridge bearings, even better ones from enduro or KYB as they are standard sized.
The chainline is adjustable as well. I never had to fiddle with it much, but it is usually reserved for BBs twice this much.
I reccomend this BB to everyone as it is stiff, reasonably light, and carefree. There is nothing particualrly special about it, but for the 25 or so dollars people are buying these at cambria for, they are a great improvment over generic shimano stock. | | Value Rating:Overall Rating: |

Date Reviewed: August 4, 2000 | | Duration Product Used: | 6 months | | Strengths: | damn light for $20, 118mm fits my cranks, i like wtb's other stuff | | Weaknesses: | dammit their grease gun is like $25, strange noises | | Similar Products Used: | cook bros. collar (POS), crappy shimano | | Bike Setup: | DBR XR-8, cook bros. RS cranks, Real 7075 rings | | Bottom Line: | seemed like a good deal ($20 @ cambria), 118mm spindles are hard to find, but i like my purple dogbones, so i got this BB. about 4 months later, it starts creaking- checked the shell, bearings and threads were both teflon-taped. removed and retorqued cranks- still creaks like hell, i dunno if its the BB or the wonderfully strong alloy that CBR uses for their unreliable artworks. hopefully won't have to use the same method i used on my cook BB (washers between spindle collar & crankarm so i could really torque on the crank without it sliding of the taper, and also to hold the spindle in place). | Value Rating: Overall Rating: |

Date Reviewed: July 7, 2000 | | Favoriate Trail: | Ribbon | | Duration Product Used: | 3 months | | Strengths: | very smooth & easy to grease | | Weaknesses: | lack of durability, after only about 800 miles of riding on this BB the bearings have developed play. This after regular once a week greasing. | | Similar Products Used: | Shimano, Race Face, TNT | | Bike Setup: | Schwinn Carbon URT | | Bottom Line: | It's crap. 3 months of riding (about 800 miles) and the bearings are shot! Shimano & Race Face BB's lasted at least a year before requiring replacment (acceptable duration). They were on sale at Cambria for $30, so it's no great lose, but i expect more from the WTB brand. | | Value Rating:Overall Rating: |

I replaced it with the WTB product for their legendary quality and dependability. NOT!!
It creaked no matter how much anti sieze, grease, teflon tape or whatever was applied to the cups. The wonderfull grease guard bolts refused to stay tight for even half a ride.
Switched back to a good old UN72, no more problems. | Value Rating: Overall Rating: |

see below | | Bottom Line: | One response to the first review.. You dont necessarily need to inject grease with the arms on.. What I do is take the arms off, and put just the hollow bolts back into the axle, then inject the grease.. When the old stuff comes out, its much easier to wipe off with the arms off. Although a Q-tip with a little degreaser works ok in a pinch. | | Overall Rating: |

3 months | | Bottom Line: | Great, inexpensive BB. You can definitely feel the difference over the cheap LX (or worse) BBs manufacturers often spec. I'll agree with the other review that the greaseguard can be messy, but for ease of maintenence and longevity, I think its a reasonable tradeoff | | Overall Rating: |

6 months | | Bottom Line: | Great Bottom Bracket. I love the Grease Guard. The only problem is you have to grease them with the crank arms on, so it gets pretty messy. Plus the grease must work it's way between the spindle and the crankarm because I have to tighten the crank bolts every couple of weeks or so. | | Overall Rating: |
