Compact with triple derailleur - issues
Just picked up a 2011 specialized secteur sport compact today. 1st road bike. Ordered from a local bike shop and they put it together for me.
Assuming the same part comes for the triples and compacts.
The problem is when I am on the high gear in the front, once I get to the 3rd highest gear in the back it starts to rub. Shifting once more with the front derailleur fixes it. But to shift out of it, I have to put an extreme amount of force. Shifting into it is fine, I could see if it were reversed or something to prevent that last shift, but something just isn't right.
So a few questions. Why is it so hard to shift back down after being in the highest position on the front derailleur?
In a setup like this, are only 2 positions supposed to be used? Or if for whatever reason, 3 will be needed?
It looks like I just need to adjust the front derailleur away from the bike just a tad. But not sure.
Thanks for any help.
that is weird, usually shifting down is easier. chances are you do need to just make a couple of adjustments. Typically the third position is supposed to act as a trim, sometimes, especially on a triple, if you are trying to use the big wheel up front with the big cog or the small up front with the small in the back you will have some rub (one reason why you shouldnt' really be using those gear combos anyways) so the added click lets you trim the derailer into place. Being that you have a double up front, it should be pretty easy to get this tweaked. Sinc eyou just bought it from them I would simply take it back into the shop andhave them adjust it, should only take 5 minutes and if for some reason they put the wrong part on there they should switch it out at no cost to you.

Brand new bike from a shop? Take it back. Sounds like a simple derailleur adjustment, but while it is new, have them sort it out for you.
Your outer limiter might be close to where you index is on your click, if that's the case, getting the der to "drop" down might be a little harder due to the force on it? Just a thought there, not 100% sure, but def, take it to the shop if it's new, let them sort it out.
Turn the outer limit screw a 1/4 turn counter-clockwise on the FD. Sometimes, the cable is really strained because that final click is too close to the limit.
More information needed.
Is the front derailleur a triple or is the front shifter a triple, or both?
The LBS should adjust the cables and derailleurs at no cost to you, for awhile anyway.
If the shifter is a 105 triple there may be a warranty issue.
FYI I'm using double shifters with a triple crank. The double shifter should have 3 clicks for the purpose of trimming. I was able to make some modifications to get my 3 clicks to shift to each chain ring though I do have some rubbing at times.
Thanks but that's not what I asked.

I really have no clue what the front derailleur and shifter. I would of said triple based on the fact it has 3 locations, but after reading what bigdaddy said, not sure.
But, it seems fine now. I think I was shifting wrong. When shifting up you really have to push that level all the way until it bottoms out. I think I was just pushing it just enough to move it, but not fully shift.
There is no need for that 3rd spot.
But yeah, its a brand new bike from the shop. Has 30 day warranty to fix anything, trade the bike back in if you don't like it in the 1st 30 days, 2 free fall tune ups, and also work in the same building as the shop. So will be no problems to get it fixed if needed.
Thanks for the replies.
Yeah, I got his thread mixed up with yours, sorry.

Other posters here made a valid comment about the FD's high limit adjustment. If the adjustment was too low, you could risk damage to the shifter by attempting to force the lever. Fortunately, you are just getting accustomed to the shifters, and there didn't appear to be a mechanical or adjustment issue.
I believe your bike is spec'd with Shimano's new 105 component group. Shimano stamps or casts the part # onto each component in an inconspicuous location. If you look on the back of your FD cage, for instance, you'll probably see "FD-5700." Just an FYI if you ever need to identify your components.
Thanks for the reply desertdork.
This bike has the sora front derailleur.
Currently the 3rd position that doesn't seem to be any use to me has the FD pushed out farthest away from the bike. Even in the highest gear (largest gear in the front, smallest in the back) there is no rub. Well 99% sure of this, not near the bike so can't check. But was in that gear and specifically checked. But there is definitely rub when I am in the highest gear in the front and then switch to lower (larger circles) in the back. But assumed there is very little point to that since can just drop to a lower gear up front, and then a few higher in the back to get pretty close to the same gear ratio that I was looking for.
So I guess what am wondering is how others have theirs setup. What position for what, and when do you need trim, etc. It would seem best to have it setup where I mainly use the 2 outer positions, and then the middle position is for trim when using the highest gear in the front, and then some of the lower gears in the back.
But yeah, something still isn't right with the fact that it takes too much force to get out of that position. Scared to even go back into it. Really need to google around and find a good site that shows how these work on how to set them up. So can just set it up myself.
