So some of you may remember the nonsense I had with my bike at the weekend.
After it being at another bike store to be fine tuned, the consensus is that it is flex on the chain ring, when being put under heavy load.
I was told that there always will be a bit of rub due to it being a slightly inferior chainset (fsa gossamer 46/36) and that if it continues to bug me then I should consider a better chainset that wouldn't have as much flex, a 105 or ultegra I was told.
Who agrees with this?

Thank you all for your suggestions

Yeh, I had been told about this but it didn't really do much.
I think I'm just going to have to wheel it along to the local (different) bike shop. If I look at it again, or hear that rubbing again, it's going under a bus, I may or may not be on it.

HAH

This is some salty popcorn

I think it to be something as simple as this. If it doesn't rub 3 gears down, then surely tilting the derailleur ever so slightly out the way, would sort it out?

This happens when the chain is not crossed.

This sort of thing is going beyond me now. I don't really know what I'm doing when it comes to front derailleurs. I just know that I've had it up to the shop I got it from 3 times, one of the mechanics is an old pal, and what they consensus is, it will always make a slight rub under pressure. I think I need to take it somewhere else for another opinion.

Ok cheers for the advice. Thanks @branwen too.

I'm beginning to think the mech isn't sitting high enough above the chain ring, after watching some YouTube videos.

That's the thing, there is no rub until the 2 hardest gears, and then its only when they are under pressure.

I know This is a single speed website but I need advice on the shimano ultegra 6800 11 speed I'm running on my cross bike. No matter how much adjusting has been done, limit screws, tension, there is still rubbing coming from the front mech when I'm in the hardest gear. The local mechanics have shown me that it's due to flex on the chain ring when under pressure and because the ultegra is set up so compact. Is there anything I can do or am I stuck with a new noisy cross bike?

Doesn't matter

One last question, for now, shimano pedals, or crank bros?

Is there a "hall of meat" thread? Accidents, crashes, injuries etc.

V nice

Please
Non tubular, folding or non

Need a replacement. Does anyone know of any out there? Preferably non drilled.

Does anyone take multi vitamins? If so, did you notice any benefits ?

What's wrong with red ink?

Pics please and this could possibly be coming back to Edinburgh

That was a great and very inciteful answer. Thanks very much for the time and effort.

I wish I had the money for the white industries pedals, they look great but alas, even if I did have the money I don't think I could justify them.

The mks urban platform look like the best bet.
