Singlespeed & Fixed Gear - How often do you re-tension your chain?

I did a quick search for this, and found nothing (though I admit, I did not look through all ~2400 results).

I bought a Redline 925 not long ago. This is the first time I've ever ridden fixed. I've put about 300 miles on it so far, and I've had to re-tension the chain twice so far (including the initial install of the wheel), and I'm going to do it again when I get home today since it's getting a bit sloppy back there again.

Is this normal? Or am I not tightening the nuts enough?

Chains stretch a little, that's normal. I've retensioned twice, once because i flipped the hub to try out SS and again yesterday. I'd say it's normal. So that's twice in ~200 miles.

It's only too loose if you can get it to jump off. I just keep riding, and every few weeks give it a good test to see if I can get it to jump off the chain-ring somehow.

Chains stretch, especially over the first couple hundred miles.

Also, over-tightening will cause premature wear.

when ever i get a flat, which these days is not very often due to there not being much debris on my rollers

Chain stretch is normal. Just keep riding. If you are really worried just get one of these and replace your chain once you stretched it too much.

Not too often. Usually only when I flat.
I can get away with this because I'm easy on my drivetrain and use a brake.

I can feel it and see it when it gets loose. I would say it happens every 200 miles or so. Depends on the kind of riding you do and if you're running brakes or not.

I'm not worried about chain stretch. I know that after only 300 miles I do not need a new chain and any stretch is still within acceptable limits. I was just wondering if my rear wheel was creeping forward, and if so, whether this was normal.

I did some calculations and found that even a tiny amount of chain stretch can lead to a sizeable amount of vertical play on the chain. I was a little surprised about that.

I do use a front brake, with some braking with my legs. But no skidding or anything like that.

Yes it is and yes it's normal
