On yesterday's ride my roadie wouldn't change into the small chain ring at the front, it wasn't really a problem as the ride was basically flat. So today I'm trying to fix the problem. It seems to be at the mech, basically I change at the levers, the cable goes slack but the front mech doesn't move. I've tried cleaning it, putting a bit of lube on. But no idea what to try now. Was hoping to do a long ride today, now thinking this is not likely to be on the cards.Thursday, 18 December 2008
Front mech woes

Is it a Tiagra? Mine did exactly the same on Tuesday. There's a pivot with a 3mm allen bolt in it, loosen that off. The mere act of trying to loosen it freed mine up, it must have been gunked up inside
ReplyDeleteCan you make the mech move with your hands - i.e shift using the lever but encourage it on its way manually? I've had the Spesh front mech seize after leaving it hungup in the garage for months after a winters use with no tlc (not saying your negelcting your bike like I would) but a good soak of WD40 around the moving parts and some manual intervention got things going again and its still going strong.
ReplyDeleteHad a good look at the photo and it looks clean as a whistle (thinks about own bike, ahem)! Try WD40 or GT85 into and around the mech (watch the rims though) rather than just lube if you haven't already.
ReplyDeleteYes Tiagra so I'll give that a go.
ReplyDeleteNot really moving with my hands, just about managing to force it but it's hard.
it looks so clean as that is the first thing I did when it stopped working, if I kept on top on cleaning and maintaince I guess these things wouldn't happen, but where do you find the time!
Rusty cables or dirty/rusty housings would be my guess. A new greased cable might save the day.
ReplyDeleteprobably need a new bike ;)
ReplyDeleteWell I always need a new bike, but you try living with an accountant!
