Messed up my left brifter, couple of questins

Hey everyone, I haven't been on here for a while, but I need your help. So I've been cycling indoors a lot, and for the past month of so, my left brifter (front derailleur) hasn't been shifting correctly. It has been really hard to get it up into the largest chainring, and it was really annoying. Today I decided to take some initiative (about time) and try to adjust the tension on the cable. I tightened it, and it was obviously too much so then I loosened it some more, tightened it some more, and ultimately, I think it ended up being way too tight. So my dumb a** decides to forced the brifter to downshift, hopefully loosening some of the pressure on the cable. Well something happened and now my brifter is real messed up. When I go to shift, it will move the derailleur, but its like it doesn't click and engage the derailluer. So, essentially, I would have to hold the derailleur in order to get it to stay in the middle or largest chainring (yes I have a triple).

So, here are my questions:
1)Do you think I broke my derailleur? If so is it worth upgrading to a better component, or should I stick with Tiagara?
2)Should I replace my cables, I've been having a lot of shifting adjustment issues and my currently cables have 2300 miles on them plus 3 1hour, 20 minute roller sessions a week since before Thanksgiving. What are the best cables to get for a good price.
3)I'm bringing it to my shop for them to fix it. I don't have time/the skills to fix it myself. Anything else I should have tuned so my bike is in tip top shape for this season?

Thanks for the help, all I wanna do it ride, and I keep running into issues which prevent this...its maddening!

i think at worst you broke a cable, but i could be totally wrong.

in the future for that kind of adjustment, use the H/L screws instead of messing with the wire's tension. (at least that's my understanding so far, i'm still learning too)

thanks, I hope all I did was break the cable, but moving the brifter levers still moves the derailleur, so I'm thinking maybe I broke something inside the mechanism. As far as the H L screws, I was always under the impression that because those settings don't change, you should leave them once they get set. But, because the cable stretches, you need to adjust that...I could be wrong though.

If the derailleur moves, you haven't broken the derailleur or cable. If the derailleur moves but will not stay in place, it is not the derailleur's problem. There is an issue with your shift lever. When you "forced" it to shift you may have broken some of the internals in the shifter. At this point, your best course of action is to take it to a shop and have them look at it. It kind of sounds like you probably don't have the experience to diagnose/repair this problem yourself.

Ya I definitely don't. The broken brifter was my first guess too, which sucks because it will be expensive to replace. Furthermore, I definitely do not have the experience. How about my other questions as far as cables, etc. Anyone got any comments?

Don't adjust the limit (H/L) screws for this type of adjustment! As long as those were properly set at the shop you shouldn't need to touch them. Take the bike to the shop and ask them to explain what happened. Someone that can see it in person and knows what they are doing will be a lot more helpful than guesses on the internet.

Ok, well we have established that I probably broke my shifter, not too excited about that but Sh*t happens. How about my other questions? Should I stick with a tiagara brifter? Do my cables need replacing? What type of cables should I replace them with?

Have a look at the park tools article on front derailleur.

http://www.parktool.com/repair/readhowto.asp?id=75

A possible reason why you can't keep the derailleur in the large and middle chainring, could be that you have the cable tension out of sync with the lever setting. The lever indexing for example may for the middle ring but the tension has been set for the largest etc. Set the lever indexing back to the lowest, by clicking it several times without any tension on the cable and then re-tension the cable so that the derailleur is centred over the smallest chainring. This should then realign everything, slight tweaks can be made to the cage position/ alignment by turning the barrel adjusters which changes the cable tension slightly, make sure the barrel adjusters are set at midpoint, before cable retension, so you can change it either way. If you find it difficult move the chain to the largest chainring, you could tighten the barrel adjuster a little bit, as the high and low screw settings should not have changed, it maybe easier setting these screws without any cable tension, by just manually moving the derailleur and adjusting.

Now's your opportunity to lose 60 grams by switching to a downtube front shifter and an aero brake lever!

Kleng, thanks for the advice, it seems like that would have been great info to know *before* I broke the brifter . But, now my brifter wont engage into other gears, like it doesn't "click." Hard to explain...

similar problem

HI,
I had a problem with the ultregra (R) shifter it wouldn't shift unless you pinched the brake and shifter together when you moved it kind of fun on a ride. I tried the WD 40 flush and it shifted up but not down I believe the spring lever was toast in the rachet mechanism.
So I ordered a new one on line they sell left and R shifters seperate do google search for your model on line and look for a deal, PS E bay is very unreliable parts in my book, had lots of bad luck, and if your bike challanged Let a LBS do the work mine was only 28 bucks for the labor.
the shifter for mine was 110.00 but hey thats better than both.
I now believe I broke mine when it was gumming up if I would have cleaned it it may have lasted a little longer I may have forced it while it was all gummed up. It seems the shimano shifters can be fickled if dirty, and are impossiable to re-build.

I think your cable is freyed, but not broken within your brifter. Pieces of broken cable can easily get in the way of gears within your brifter.

Hmm, that is an idea which would be muuch better than a broken brifter. It is going to the lbs no matter what, but new shifting cables are definitely in order.
