    Learn from my goofs! ...Check chainlength w new wheel. ...Practice wheel change.

    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.

    I'd say you were lucky. Pretty often the chain goes into the spokes when it's too short for the gear combination you're using.

    No, that's when my der is mis-adjusted, which often happens when I change wheels -- but thankfully no damage. I did adjust it for this race but I forgot to check chain length for the big-big.

    I just mounted tubies on a second set of wheels but I don't think they'll be hot swap-able because the rims are different widths. The first set are Major Toms which are 23mm wide rims (great for mounting 'cross tubies) and second are some old Mavics which are 21mm wide. I've tried to set it up so I can use the barrel adjusters to move the pads in and out between wheels but the pads also need to be adjusted up and down. The Mavics have a very narrow brake track, so the pads can really only go in one position, which puts them borderline high on the Major Toms. I sure don't want my pads rubbing and popping a tubular. It won't take too long to adjust them, so I can pick a wheelset before the race, but I don't think I'll be able to use the other set for pit wheels during the race. I would have preferred a second Major Tom wheelset to keep things consistent, but I'm a scrounger and couldn't pass up a nice cheap pair of tubular wheels that came my way. In reality I'm not likely to pit anyways, if I have a major mechanical, I'll just curse and walk off the course.

    FYI I run the same cassette on both wheels, but I run my chain a little tighter than standard. Helps guard against drops I guess. The way I'm set up, on most courses I'm on the small ring most of the time, only using the big ring for the long straightaways, like the start/finish line and maybe another spot on the backside of the course. So I'm at least in the middle of the cassette before I get on the big ring, and the chain never gets near my biggest or even second biggest cog. Since I'm spending more time on the small ring I think a shorter chain helps.
