I do now, this was before I got the confidence/stupidity to believe I could do it myself :P. They were probably fine when it was built, came from BC and they don't usually sell tripe no matter how cheap it is. I just re-dished it a few times (my first dabble in nipple tweaking) when changing between 5, 6 and 7 speed freewheels on my tourer and that was more than likely the dagger in its back.

I had exactly the same problem with a rear wheel. When spokes have been in a wheel for a good while, the points where they meet/cross each other get little dent or groove in them (just like you see in old hubs where the spokes leave the flanges) and the noise is the spokes moving across these dents as pressure is placed on them. It drove me nuts for ages because it was only happening when I was off the bike and spinning the wheel, the only time you can safely inspect it moving, because there was no pressure being exerted on the spokes. I came up with the aforementioned dent theory but couldn't work out which spoke/spokes were making the noise so I tightened them all a quarter of a turn. This got rid of the noise for about 20 miles or so but it came back. I repeated the quarter turn, again on all the spokes, and it's been silent ever since (500+ miles).

how loose are the cups? do they fall out entirely or will they sit in the tube? I had a problem with a 1985 peugeot where one of the cups was slightly loose. it stayed in the tube without wiggling about but could be pulled out by hand, if you get me. didn't bother replacing it, I just make sure my headset is properly tightened and have had no difficulties with it.

When I was back home (Northern Ireland) visiting family and friends over christmas, a friend and I 'fixed' a crappy cheap MTB that someone had given to my dad. we just, again, used what we had lying around. could only find a 13T cog so ground the bigger two rings off another MTB's chainset leaving the granny ring (28T 56"), looks a bit silly having such a small drive train but coupled with the high BB gives shit loads of clearance. tons of fun to boot.

pj [quote]stevo_com whats the average GI on here anyway?
My current bike is also my first fixed. quote]
hence the absurd gear?
PJ see:

When I built it last year I just used the crankset I had lying around and the cheapest cog I could get my hands on and ended up with that 52-20. Then a friend gave me a 16T and it seemed more comfortable so I splashed out on a Surly one (which was subsequently nicked, waiting on a Dura-ace replacement).hippy, yeah, was considering a 46T chainring with the new crankset so that would be about 75" I reckon, will have to wait for funds though. my current crankset has the chainring fixed to the right crank so it wouldn't be just a case of a new ring.

When I get a bit of cash I'll probably upgrade to a better/smaller chainring and a couple of different sprockets and see what works best. Til then 85.4GI makes for interesting red lights, seeing what it would be like brakeless.
yeah, it's nice, right in the bus lane. I would've normally seen it, presuming I was on the ball, but that time a bus decided to overtake me just deftly brushing my elbow so my attention was towards the heavens, hoping my plan of 'repent on my deathbed' could be inacted in the split second before I went under the wheels on the bus, which do actually go round and round, contrary to popular belief.
