Hello

Can someone tell me how you adjust the front derailer on my bike please? The chain slightly catches and so I can hear it rattling along as I’m peddling. My issue is I cannot see a high or low screw anywhere on this derailer. It’s a Shimano 105 group set on my specialised Roubaix 2018 bike. 
 

Your advice would be much appreciated

Are you aware of the trim

Are you aware of the trim function on the 105 shifters? There are actually 4 clicks in the front mech shift lever designed to minimise the noise. Does it only happen in the biggest and smallest cogs?

Also a general word of advice on fiddling with it – start with quarter turns on the screws, tolerances are pretty tight on 11sp. A torch helps with eyeballing clearance between the chain and the cage.

Thank you, Tom.

You adjust it with a hex wrench, so if you were looking for screws you might have missed them.
