Chainring rattling and left shifter.

Schecter01

I know I'm doing something wrong, it's not the bike itself, I know not to have the chain cross from he large chainring to the lower gears on the Cassette, but as soon as I change from 11 gear up to the large chain ring it rattles automaticly until I change the rear derraileur, also the front derraileur has a couple of setting, 3 or 4 clicks each Way? Is this just to stop the chain rubbing in certain gears?

Sounds like the front dérailleur may need adjustment

I've been riding the smallest cog on the smallest chainring could that have thrown it off? As I've read your not supposed to ride the smaller cogs on the small chainring and vice versa, so when I want to change to the large chain ring I should change when I'm on a middlish cog?

So you've a triple (3 rings up front?). Small ring front and small ring back would be a no no (cross chaining).

You can adjust the front dérailleur so you can run small back and middle front without rubbing.

No just 2 rings up front, I meant if I change to the large chain ring when I'm in say the 5th or 6th cog of the cassette would that be standard procedure? Crosschaining that was the term I was looking for

If it's an 11 speed 105 5800 double front chainset then the lever has 4 clicks resulting in 4 positions for the front dérailleur. Basically it's to allow an amount of cross chaining. It's a trim function and can be a ba$tard to adjust (for me anyway ).

Once you click the paddle 4 times it's at the lower stop with the chain on the inner ring. As you select higher gears on the cassette the chain will start to rub the front dérailleur. Shift the left lever to the first click. The front dérailleur will move slightly to stop the chain rub (but won't shift to the big ring). The next click of the lever will shift the chain to the big ring with the final click allowing the dérailleur to move out another bit avoiding chain rub as you shift to higher gears on the rear cassette while on the big ring. By then you'll be up to 60km/h and hopefully won't be able to hear a thing with the wind in your ears

I hope that makes sense.

Thanks crosstownk that makes perfect sense!
