Chain rubbing on front derailleur in highest gear since new

[DuncanM]

Hello,

I bought a Specialized Allez in May, and it has always had a slight bit of chain rub in the highest gear, only on the right pedal downstroke if that makes sense.

Hanging the bike up and watching it closely as I slowly pedal, I can see that the chain gets closer to the derailleur as the right pedal is at the top of its travel, and then lightly touches it for a bit on the way down.

I'm a little disappointed with this tbh, and it didn't get picked up in the free 6 week service - bought from Evans-. I have emailed them saying I want it sorted properly.


Question is, how bad is this? Should I still be riding it whilst waiting to book it in?

Checking again the chain moves considerably from on side of thr derailleur to the other in any gear, surely something ain't right there?

Around 3mm.

As above reply from your description it sounds like the front ring is bent, causing chain rub only at certain crank positions ?? Straight back to Evans would hope they'll sort this out.

A quick update.

Evans were okay but not great as they didn't want to contact Specialized for me.

I ended up sending Specialized an email and they agreed to pay for a repair, an upgrade to a 105 chainset.

So super service from Specialized, mixed feelings about Evans if I'm honest.
