Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

What do I do now? Bought an '05 Pista last month, two days ago I had LBS change the 16 tooth and put on an 18 tooth. Now the threads that the lock nut go on are stripped out. Damn it. Am I right to assume it's just a cheap hub and the larger cog put more torque on the threads against the nut and caused it to strip? What now? A better wheel set? I put the origonal 16 tooth cog on the other side of the flip flop hub. Is this common as problems go? If I sound dumb about this it's only because I am, sorry just another newbe. thanks......

Two days ago? I'd take it back to the shop. At least see what they say.

I would take it back and tell them that they did a poor job and that they owe you a new hub. Maybe the mechanic at the LBS has never worked on a fixed hub before and tried putting the lockring on against the threads. If this is the case i would be outraged, this could have caused you serious bodily harm had it failed on you in a dangerous situation.

The threads on that hub are prob. not machined very well. Good thing it died and not you. Invest in a good hub, and possibly have the BB checked on your bike. We had problems with them at the shop I used to work at. Seems that the factory did not always tighten them, and lots of shops do not pull the cranks and check before they sell that bike.



Buy a level hub. www.levelcomponents.com and never strip a hub again.

a bigger cog should make skidding easier on the hub...
i would guess that the shop didn't tighten the lockring down enough...
if the lockring leaves room for just a little play for the cog, every time you skid you're slamming that cog sideways into the lockring...
whether it's a shoddy hub or not, the shop should be helping you out with a new one...

Agreed. As a Pista owner I would say the stock hubs aren't that bad. Sure, you can get better but they aren't total garbage. I would talk with the folks at your LBS. Sounds to me like someone hamfisted your lockring on.

What first gave you an indication that the locknut threads were stripped? were you removing the locknut?
Or was it loose?

Excellent question. 2manybikes has been a mechanic I would guess. I know the Bianchi hubs are not "that bad" but because the threads cut into them are not as well machined as a philwood, paul, or campy hub, they do not grab a lock ring aswell, or a cog. The more you remove and change the lockring the more you risk stripping.

According to Sheldon Brown, the problem is usually with cheap cogs rather than cheap hubs. The cheap cogs have a shorter threaded section, which puts more stress on the threads... since the hub is Aluminum and the cog is Steel, the cog will tear up the hub. That's why you should use a good quality cog.

Hi, I think your right on. This LBS is one of very few that understands, has, and respects fixed gear in my area. He did say that Soma lock nuts have a much more deep machined thread, he said they dig into the hub thread and that once they are on they are hard to get off. Oh well.The cheap nut was the one that came with the cheap bike, the LBS had nuts on order. Maybe I should lay off on the skidding till I get a different nut for the side that is still ok.

Well, my Pista should have arrived Friday.
It didn't, but I'll count that as a good thing since reading this thread.

I ordered my Pista with two cogs: the factory 16t cog and an 18t cog on the other side.
I asked my lbs to match the make of the second cog with the factory cog.
Intuition, eh?

Anyway, I wonder what, specifically, I should ask my lbs about the assembly of my Pista.

if they stripped out your hub, you should really consider violent retaliation. Or a burrito. Kev got me thinking about burritos, now I am stuck.

Dare I suggest a gordita?

Definitely bring it to the attention of the shop guys as something they are responsible for.
