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)

CETMA rack users - a weird mechanical problem

So the front wheel on my commuter was a little out of true so I took it in the coop and worked on it. I got it about as close to perfect as I could. Since installing my CETMA I noticed that the wheel was a little out because the rack pushes my front fender down a bit so it shifts around and rubs the tire from time to time (I have a solution in mind for that part of the problem already.).

Here's the thing. The wheel is dead true when I'm sitting down and pedaling. Same when I'm standing up and coasting (it's a singlespeed), but any time I'm standing up and pedaling there is a noticeable wobble to the wheel. The tension on the wheel is not the best. It's probably worked its way loose since I last worked on it, but I'm also wondering if the uneven pressure on the bars from standing and pedaling is causing transmitting some lateral flex to the fork.

Anyone?

1. Make sure your cones are adjusted correctly
2. Make sure that the CETMA mount isn't allowing your wheel to slide around


That's all I can think of right now. Good luck.

are your hub bearings correctly adjusted? That could be the issue

Good questions about the bearings. They are Surly sealed hubs. I haven't noticed any play.

Just because it rubs doens't mean it's out of true. No tire is going to sit perfectly, perfect on a rim. Especially cheap tires. If you can flex your wheel while out of the saddle, that means your wheels is dangerously under-tensioned. I suggest you get a tensionmeter and bring it up to spec before you hurt yourself or break a spoke.
