Ultegra Brifter problem following crash
On Tuesday morning I hit a patch of loose gravel at the side of the road and would up going over on my left side.
The left brifter must have hit the ground first and was twisted inward on the handlebars, and scratched up. I got back on and rode home feeling a bit stupid, but otherwise fine. When I got back I loosened the appropriate bolt and straightened the thing back up. First ride since, the shifter's not working quite right - when you shift up onto the big ring, pulling the cable tight and moving the whole brake lever rightwards, one of the little metal sort-of sub-levers stays out instead of returning like it should. You then have to repeat that same motion to sort of dislodge it and get it to return, before you can use the innermost lever to drop the chain back onto the 39
I've sprayed GT-85 into the guts of it until it's run onto the ground, and it's not gummed up with anything - the whole bike is only a couple of months old
Is there anything else I can try, or do I need a new brifter?

no, you might need a new shifter.Colnago Addict!0

I think your best bet would be to take the whole thing off the handlebars and have a good look inside at the shifting mechanism. You'll need to take the gear and brake cables out, and unwrap one side of the handlebars, but it's no more work than if you replaced it.
Once it's off the bike, take the rubber hood off and dismantle as much as you can. You may find it's something simple like a small stone getting in the way, an internal spring has come unclipped inside, or part of the mechanism has been bent in the crash but can be bent back again.

Check to see that you haven't damaged / distorted the lever body. Apart from replacing the body or whole lever assembly, there's little user-serviceable inside unless you have the skills of a watch-maker and patience of a saint.Make mine an Italian, with Campagnolo on the side..0

Thanks guys, I've just been riding it on the big ring over the past few days, I'll have to get some more cables tomorrow before I take it apart.
Thanks for the replies0
