So I was having a great race on a great course last Sat. ...Just a fun local race. I was feelin' the fun flow. Last quarter mile of race...
I'm getting lettuce clogging my small cogs so I shift into big ring and use bigger cogs. I go up a rise and downshift once more: and LOCK UP. I've shifted to the biggest x biggest and it was a diff wheel than I'd sized my chain for, with bigger big-cog and the darn chain stretched rod-tight. I get off and soon enuf get my rear wheel out then go to put it back in. Like 1000 times before. Well, I have all sorts of wheels. But they all go in well enough despite small diffs. I'm actually in the lead. My lead disappears as I fuss and fiddle with that wheel! I'm not rushing or panicking. Stay calm. This is easy. Just put the wheel in. I adjust der to small cog. But it won't go in! Finally...finally...I get going. I coulda still won if I'd just run at the get-go but my knee gets insta-sore, even tho I love running. I couldn't believe I couldn't put my wheel in! So I kept fiddling. It wasn't even a mechanical -- it's just putting a wheel in!!! Argh!
So check yer chain in all possible wheels for big-big, just in case. Tho you're not "supposed" to ride it.
And stop in middle of fast practice laps now'n'then and just pop that wheel out and back in again. For all your wheels.
