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)

Rear hub/lock ring on Langster

Two days after I bought my Langster, I managed to unscrew the sprocket while resisting the pedals and this popped off the lock ring and stripped the thread off the hub. My LBS replaced the entire rear wheel as a warranty job, but tonight after I was doing a bit of skidding the sprocket has come loose again (second time in 2 weeks).

I'm going to take it back in to the shop tomorrow, but I just though I'd ask if this was a common problem. Is the hub or sprocket poor quality, or should I have paid a bit more for a Bianchi Pista? Or am I just really unlucky or ham-fisted? I'm not all that heavy (about 70kg/150lb) or powerful so I don't think it's me.

Even if they tighten the cog and lockring by hand, you will certainly need to tighten the cog and lockring again after some riding.

I usually ride up a large hill, or rotafix the cog on, then tighten the lockring down as hard as possible...Even after it was tightened down by hand.

Thanks guys, I just hope it's a matter of tightening it up. I'm missing all the nice weather with the bike ending up in the shop all the time, and we don't exactly get too much nice weather here
