Hi forum!
So - I've bought my first Triban. The 520. :-) I love the bike but I've noticed the gears are a little noisy and clunky (particularly the front derailleur which really rattles while changing and takes an age to settle into the gear).
My question is: Is this normal for a derailleur gear set at this price point? Or should front and rear shifts be smooth as butter? Should I take the bike back to decathlon for a tune up? (I don't live close, so this would be a trek!) Any home tips for tuning the gear changes?
Also, is it ok to use the full range of rear gears on the middle front gear? Or is that doing it wrong! So far I am tending to stay on middle front gear except on hills.
Sorry for the newbie questions - this is the first derailleur gear bike I've had in a decade!

Sorry for the newbie questions - this is the first derailleur gear bike I've had in a decade! hi, welcome to the forum and Triban secret society It is not normal and can be made work correctly. I'm not sure what the 'smooth' is, but it should and can be fast, precise and accurate. It is just matter of proper set up. Sure you can take it to the Decathlon or LBS, but I'm always proponent of learning and doing such stuff yourself. It is a task that needs to be revisited occasionally and spending time and money so that somebody else does it every time is not very effective or rewarding. Besides, think what happens when you chain slips due to miss-adjusted FD and you are nowhere near home or LBS. Internet is full of 'how to' videos, here is the first one that comes out and GCN is generally very good: www.youtube.com/watch?v=Ea03ChN-7VgJust stick with trying, it is unlikely that you'd make it worse and with time you'll become as good as most bike mechanics.

+1 for above advice. I would add, it won't go right first time. Make a cup of tea, take your time and stay patient. Rest assured that neither fiddling with limit screws or tension will do any damage.
As to using full range in the middle cog ain't best practice. (Without checking I'm assuming that the 520 has a triple). Avoid crossing will give better feel, avoid rubbing and make components last longer. Use granny ring (the small one on front) for low gears, big ring for high gears, and middle ring for middle. There is a lot of redundancy on a triple - you don't really have 3 x 10 gears. Sorry. I've had a beer, and may not be making best sends.

As above, but the front change won't be as good as the rear unless you get the knack.
The rear mech is pulling the chain on the bottom run which is only under the tension of the mech.
The front mech is trying to move the top run which is under tension from you pedalling, to get a smooth shift you must ease off the pressure as you change, if you don't it may be slow and noisy or not change at all.
