Halfords fobbing me off?

Hi all,

Yesterday I purchased my first road bike, unfortunately I bought it from halfords. I asked them not to touch it! An hat I'd set the bike up.

All went well shimano 105 rear dérailleur changing like a dream but the front. I limited the stop screw for the small chainring and and the biggest cog on the cassette. Changed down to the smallest cog and it rubs horrendously. Adjust it with the tensioner and it rubs on the inside when I change back to the biggest cog?

Think halfords were fobbing me off when I called them and said it was to be expected? I should only have access to the top half of the cassette in the smaller chainring and the lower half in the larger?

As this is my first roadie I couldn't tell him that I thought it was a pack of cods wallop!

Have I got a duff dérailleur? Or is what halfords correct?

Any help is very appreciated

Dave

Why would you expect help from them when you First told them "Not to touch it"?

Chain rub can be expected in the cross chaining positions. Small chain ring in front and smallest cog in back as well as large chain ring in front and largest cog in back

^ This, it is very common. Also note that just because one person doesn't get chain rub on their bike when cross chaining doesn't mean you shouldn't. It can be dependent on the chainstay length, chainline, front derrailleur cage geometry, blah blah blah...

Look at it this way, the rubbing will remind you not to cross chain! :-)

Bollocks to both of you!!! While many of these mechanics can be tossbags, you should at least make sure you're more competent than them. What did you expect for taking a pop at them?

No, you don't have a buggered derailleur, it's just not installed and adjusted right. Follow this Park Tool - front derailleur adjustment guide.

And they're partly correct, you don't want to use all of the cassette in each chainring. I typically avoid the two extreme gears in each chainring since they're duplicated anyway. So in the big-chainring, I'll avoid the two largest cassette cogs. And when in the small-chainring, I'll not use the two smallest cassette cogs. Aside from limiting the excess-friction and wear from cross-chaining, it also limits the amount of chain-sweep the front-deraileur cage has to deal with. No rubbing.

Thanks for the posts people, just never had any experience with a roadie setup. I've now set the bike with a slight cross chaining. Never come across it with any hybrid or mountain bike I've had in the last 30 years!

Veloglock I am indeed from the uk a little outside of London

Thanks again Dave

Not some region, but some decade, say the 1950's

For the OP, as you didn't want them to set the bike up, it's your problem if there are any issues, most bikes from the box will need an initial adjustment, if you go to a good LBS, this will cost you at best £40 for a basic service, if not more, which you could have got for free if you had let Halfords do it.

According to Shimano it should be possible to adjust the FD so either chainring can be used with any rear sprocket. That said, you'd want to limit the use of crossed combinations to the occasional, situational use like topping a hill that you could on the outer ring and finding yourself one or two gears too high. Like wise you might want to ride crossed over for a short wall you're taking at high speed, and wanting to step the gears down in small bites.

105 has a trim (double click) feature for the outer position that allows you to re-trim the cage a few mm when the chain is coming from an inboard angle. As I said crossed-chain shouldn't be a regular thing, it's less efficient, and increases both chain and sprocket wear, but is should be possible without rub. (not allways possible in the extreme big/big, though usually is, often not possible small/small because the chain touches the larger sprocket on the ay to the smallest, something that cannot be adjusted out via the FD).

That's the technical end, now for the other.

I don't know why you told the shop not to touch the bike, but having done so, I can see that they'd be less than interested in cleaning up your work. If I were you, I'd buy a couple of beers, put on your best sheepish grin and go back saying you were wrong to think you could do it yourself, and asking them to complete and check the assembly and adjustments as they would have in the first place.

Wow sorry some of you are of the understanding I was rude to the guy from halfords? I just stated I'll set the bike up myself.

Due to my lack of experience with a road bike I asked the advice from you guys

I didn't think you were rude, but also don't understand why, especially lacking experience, you didn't let them deliver it assembled and adjusted in the first place.

There are a number of decent tutorials available on setting up the FD, and you should have no probelm if you pay attention to cable tension and the double click trim feature. You may not get all rear positions not to rub, but you should have no problem getting all but the most crossed to be fine.

The problem is, that it came across that you were Halfords bashing, in the UK that's a sport common on Singletrackworld. You asked them not to perform a service, and then were unhappy when you found you couldn't do it yourself. Lesson learned.

Maybe I could have chose my words slightly better appoligies. Them not setting up the bike was a time issue as well as my local branch being notorious bad at setups. First hand experience to be fair.

Anyways no disrespect to halfords or their employees. Just needed a bit of confirmation that what I was told was correct! Now I know there is a slight amount of cross chaining. Bike is now setup and running like a dream!

Thanks again Dave

Glad to hear you got it sorted. Having competent help in shops is a common problem in the U.S. as well. Due to the nature of small mom & pop operations, it's not possible to hire mechanical-engineers to set up bikes. It's mostly state-school and university students that do the bike-assembly and they typically have rushed deadline. The result is there's often non-optimal set-up of bikes and many are returned for tune-up fixes; causing the common LBS bashing seen here.

I went through a not dissimilliar issue setting up the 105 on my wife's bike. Couldn't for the life of me get the trim function to work in combination with no chain rub in the cross chain combos.

Read the Shimano set up instructions! Small chainring/small cog chain rub is to be expected on the two smallest cogs. They mention it in the instructions.

The large chain ring trim should eliminate any chain rub in the large/large combo. If the trim function isn't working smoothly, look at decreasing your cable tension.

Just a thought as I have a compact frame I presume the cross chaining factor is compounded!

A compact frame has nothing to do with chainstay length the compact refers to the front triangle, looking at the current range of bikes that Halfords sell, none have compact frames, the Carrera and Boardman bikes they currently have are semi-compact which is now the almost standard design for modern road bikes.
