Surly Ultra New hub review

Do not ever buy a hub made by Surly. I will lose my mind if I try to understand why anyone at this company thought that a 5mm allan bolt is sufficient to hold a rear fixed wheel in place. First I had angular contact bearings that were impossible to adjust, and now I have this obscene axle bolt that stripped the first time I tightened it. I used a torque wrench and watched it strip way before I reached the torque specified in the instructions (35-40 ft/lbs). I have lost all hope for this company, and just wanted to warn other people that this hub is worthless.

It's actually a 6mm allen bolt (similar to Phil Wood hardware). If you used a 5mm wrench, there's part of your problem.

It's pretty well-known that Surly hubs are troublesome. Research before buying.

I used a set of bolt on surly hubs for a year or so.. I hated the for the noise and the cone nuts would come loose. But yeah. 6mm.. http://surlybikes.com/parts/hubs. Last sentence of the second paragraph.

The one that I just bought came with a 5mm bolt, and that is what is in the spec sheet. They must have changed it later.

I feel your pain. I just overhauled a New (not Ultra) hub for the winter bike. Crossing my fingers.

I've never understood whats the big deal about Surly hubs. I have two compete wheelsets and one other rear wheel (a total of 5 wheels) with Surly hubs (the older model with track nuts) and they work fine for me. Yes, it sometimes takes a bit tweaking to get the bearings adjusted right, but a minor issue in the long run. My oldest pair of Surly's (8 years old) were on my rain-beater conversion for years and they still spin smoothly and have never even been touched by a cone wrench.

....Could this be a quality control issue, perhaps?

The new model hubs were better, but it seems hit or miss. I bought a bicycle with new hubs and the "cones" were either not adjusted properly to begin with or they had come loose. The problem is that replacing the cartridges is a real chore because the axle does not have a shoulder, and even with a proper bearing puller the angular contact cartridges break apart before being pulled out of the hub. Then getting the new bearings properly adjusted takes forever compared to loose ball hubs.

Those, however, are more subtle points. I really can't understand how they could mess up an axle bolt like that.

More or less this. Two years, no problems. Thinking about messing with it just to see what's up though.

Perhaps.

I had a New hub and the cone & lock nuts would loosen up on their own over time. I didn't catch it a couple times and so the bearings were wrecked.

Have two ove the new hubs on the dmr, the rear has been somewhat trouble free, after modifying the sucker to fit a shouldered axle. The front is still a total pain in the rear.

Have a 2010 Surly KM and have had zero issues with the hubs at all; they've had one overhaul and that was 5,000 miles ago.

Front hub has been overhauled 8 times in a 1 year period here.

I think its just usage combined with limited quality control, perhaps?

You do a hell of a lot more offroad riding than I do. My KM has been relegated to lending to friends and commuting occasionally.
