Don't you love the way your fixie talks to you? Last night my rear end was talking and I wasn't listening. I'd tightened up the track nuts two days ago, what was it whining about. I thought maybe it was just in need of some lube. I was hoping against hope it wasn't another Surley hub going into self destruct mode. I had one blow earlier this year and had to walk a bike home a mile.
It wasn't the hub, it was my fixed gear letting me know it was going to throw the chain, cause it could. A little chain stretch was just enough to allow the chain to pop the rear 17t, and foul up the crank, wedging between the crank arm and the BB tube. At least it wasn't a busted chain, there was a storm brewing. I had images of walking/pushing the bike home in a thunder storm.
Fortunately I got to ride instead.
Note to self, listen to the bike, it's telling me something.
