What's the story with my front derailleur, please?


Recommended Posts

What gets to me is that he paid his LBS twice and they (people that do this for a living) cannot figure out that it is set too high! :cursing:

Excactly, If they fitted it incorrectly to begin with, you should no tbe having to repay to fix their cock-up.

Did you pay for it to be fitted, or did you get free fitment because you bought it from them?

 

Don't think it makes much of a difference. They fitted it and he paid and it should have been done right the first time round.

I agree 100%, see my earlier post, just wondered if they got more of a slapdash job as he didn't pay for the fitment. Either way the LBS that fitted it should take liabilty and sort it out as they were they muppets that fitted it wrong the first time. The problem here is would you trust them again? So you kind of stuck between a rock and a hard place.

Wow! Thanks for all of the replies. :D

 

I'm relieved to hear it's only a case of adjustment and not a wrong derailleur.

 

I'll have a go at setting it up again this weekend.

 

Hopefully I can get away without having to adjust the H and L screws.

 

Boet, I think you're going to have to physically move it lower. As in loosen it and move it lower. You'll need to adjust it again, as the cable will need to made 'tense' again. The H and L screws are only for the movement it does while shifting and sets a max movement on each side (most inward for small ring and most outward for big ring).

Some of the places I ride, desperately require the Granny Gear, funjunkie. ;)

 

OK, I took my bike back to the second [better] LBS on Saturday...

 

The guy immediately knew what I was talking about and explained to me, with the aid of a newer Specialised as an example, that the newer derailleurs are made differently. The 'lever' part of them is shorter, as I understand it. Apparently the geometry of my 2006 frame is now defunct.

 

He showed me, when we shifted onto the large chainring, that there minimum clearance there, around 1mm or so.

 

Short of adjusting my chainring ratios, there isn't much I can but live with it, unfortunately.

 

My best bet is probably to cut my losses and look for good used derailleur.

Smells like BS to me... sounds like the first LBS fitted a 2 x derailleur. Refunds all round, and get the right part for the job.

That's total BS - because deore does not come in 2x10. That is a 3x10 mech, and should work perfectly, and as JB said already, the correct spacing is 1mm-2mm, not 3 or 10mm.

 

Name the LBS's you are talking about?

Total and utter BS, mate. We can see from the pic already that the spacing is incorrect. Move it approx 1-2mm down the seat tube, reattach the derailleur cable and adjust accordingly.

 

Whoever the person at the LBS was is talking out his 4ss.

FD is most definately too high!

 

Also check your chain length is correct and you have the right tension and it is not sagging in the granny gears.

 

Did the LBS refit the same chain or a new one? If new you may need to remove a link or two but adjust the FD down first then see how things look.

OK, so here's the latest on this saga...

 

I purchased a new gear cable this past weekend and fitted it myself, because I discovered a damaged cable upon its return from LBS #2.

 

I realigned the derailleur and dropped it. It is now pretty much dead on 1mm from the top of the large chainring. It changes gears very nicely too.

 

...but the chain still drags along the bottom of the cage.

 

We've been playing around with the idea of cutting the bottom of the cage off and trying to extend it downwards with a small plate, fitted with pop rivets.

Something is obviously not quite right. If you are in the small chainring in the front, does the chain drag on the bottom of the cage in all the ratios at the back?

That looks like a stuffup.... I would ignore the granny gear. Make ajustments to derail not to move to granny. Remove granny, save 20 grams..

 

Damm no.. remove derail and both small rings and shifter and cable, save 400grams. Simplify.... Get fit, get Strong... Rule no 5... :w00t:

still looks a little too high for me, if you drop it by 1mm, you should have clearance in granny, bearing in mind once you get towards the smaller rings on the back clearance is almost always going to be problematic
