its booked in first thing tomorrow, was just weighing up doing it myself.
39 seems low for most time trials I have ever ridden in, not many hill around your way is there. Pop a 46 in.

It's something I'd just changed, no I don't think it caused the problem, I also don't think incorrect adjustment of the derallier caused the problem, it could be the alignment though and the fact I was big big. It went bang as I changed into the 23 mid way up the hill so yes probably my fault. And yes I'm feeling rather sorry for myself!

Unlucky. Something similar happened to my wife's bike but it was after a puncture and I think the bike had been laid down on the derraileur at some point.
It also happened as I was riding around Belgium with a friend earlier this year. We were on a steep climb and i heard the tell tale tink-tink-tink as the derraileur cage nudged the spokes, I told him to quickly change up a gear but a couple of seconds later it all exploded. I do think that sometimes it can just happen.
While big-big is not a good way to ride I very much doubt if it had anything to do with the mishap, if anything that combo will bend the cage away from the spokes, not inwards where it might catch. good luck fixing it, the damage to my wife's bike was a chain plus front and rear derailleur, but luckily no damage to the wheel apart from light scratching to a couple of spokes.
I thing the big/big combo under the major stress of a steep climb could be enough to twist the rear mech into touching the spokes, even without an hanger alignment problem, if the limit screw is even slightly out.
What I can't understand is this reluctance to use the small chainring. It must surely be compromising the cyclist's efforts trying to grind up a hill in big/big when easier/more efficient gears are available on the small chainring.

Yes, I think because I was on a TT training run (and going ok) I switched into "I don't need to change front rings" mode, where if I had tackled that hill on a "normal ride" I would have definitely switched into the 39 at the start of the hill. I'm only 13 months into owning and riding my bike and learning all the time (and making mistakes).
Big/big will cause the chain set to wear more quickly, not work as efficiently as it should, and maybe rub a little on the fd, but it won't send the chain into the spokes or cause the rd to go bang. Unless isn't not set up correctly. Anyway, I'm sure the lbs will sort you out

This is what I was getting at, will probably pay full rrp at lbs, but if it's properly set up and done well then that's fine before anybody shoots me down, I'm inclined to use lbs anyway because they are good and I've got an open 10 TT on Saturday!
