Durable hubs?(4 posts)

Durable hubs?Woof the dog
Feb 3, 2003 12:57 PM
American classic rear hubs that weigh 230grams.

How do these hold up long term? I had them once for a short time and they'd behave weird, like be a little tight and really tight after rain.

This is for a racing wheelset that will be ridden hard under 140 pounds of purebreed dog power.

Please tell me of your experience.

Woof the dog.

I am 140 lbs. as well and currently have a set of the Micro/Ultralight Hubs from them with around 1500-2000 miles. I hate to put any bad info out about them because they are fairly decent for what they are: an ultralight racing hubset. I used mine for general commuting and group rides in both dry and monsoon conditions and haven't had great luck. Mine were 1 generation back from the current with the unsealed bearings and the microlube port on the hub. After less than 200 miles of use, the front bearings were very rough rolling. After attempting to inject grease through the microlube port(joke, like I'm going to fill my hub body entirely with grease, two grease tubes later) without success, I tore them down and cleaned and repacked, only to have the same failure about 500 miles later. The rear hub bearings are bigger and better and there are twice as many of them. However, I had trouble with the pawls on the hub engaging reliably. The hub would frequently skip through about 90 degrees of rotation before engaging and would shear edges off the freehub in the process. Now, I have to baby the application of torque to avoid the tooth shearing effect.

In a race situation where you are always on the pedals and don't have big gear starts, these hubs should do great. But in my commuting, where you occasionally will stomp on a 42x14 or something to get rolling from a stop, these don't seem to be up to the task.

I have just recently converted the hubs to the fully sealed bearings for $40 from AC but I don't have any miles on them due to my Minnesota location. In my two dealings with AC, they have been very helpful and shipped my bearings immediately. I don't want to bash them for the trouble I've had, because I may have been asking a little too much of the hubs to expect them to hold up for the daily commute in monsoon conditions. I will definitely give them a second chance and buy the freehub and washer necessary to fix the skipping problem. They definitely are light.

cool thanx. I will keep that in mind. I will make sure I have good bearings too.

Woof

I've had an ultralight rear and micro front for a year and a half now, and while they haven't seen too much use (broken wrist last May pretty much killed my season), I've got around 400 miles on them, with a couple of rainy races. I weigh in at 145 lbs soaking wet, but have long legs and hammer more than I should.
Both hubs have the greaseport, but the rear bearings all have both seals in place. I figure I got some hybrids, from when they were starting to switch over. I haven't been able to disassemble the front hub, but I haven't tried very hard.
I do use the greaseport up front, with grease from oddsandendos.com (it's very light, non-tacky grease for use with the greaseport rears, to keep the pawls from getting stuck in cold weather, but it's grease light bearing grease, too). I know it adds a few grams to the front hub, but I built them with 14/17 Sapim Lasers, so it evens out.
I made sure the rear bearings were packed and the axle properly adjusted on the rear hub before I ever rode it, and even after around 70 miles in pouring rain (hey, the race must go on, right?) the rear was pristine inside. I did recently open it up to check the pawls, and everything looks sharp, with no shearing or wear.
The front spins like a dream, even packed full of grease, though it does weep for a few miles after being injected. I can understand.
So, for race wheels, I'd say yeah, just keep them clean and greased. Probably not the best choice for everyday rides, but everything's got tradeoffs.
