Evening all need some advice

Bike has just been for service had gear cables and chain replaced and brake pads

Have a shinamo 105 gearset

So was changing through the gears in first gear was still rattling

I thought I’ve got this and watched some you tube videos on indexing , stupidly I though let’s just go through the full tutorial on derailer placement etc

So I moved the derailer etc with the 2-3mm gap and then went to re attach the cable

The mechanic has cut it to length and god knows how to get the cable back on seems to short

How can I release some slack to get the cable back on should I even try or just bite the bullet and tell the mechanic I messed up

If you're new please join in and if you have questions pop them below and the forum regulars will answer as best we can.

Make sure the shifter is in the lowest gear (small paddle clicked twice), that any inline cable adjusters are adjusted to be as short as possible and that the end of the outer cable is properly seated. That should give you enough inner cable to clamp.

Cheers I'll give that a try in the day light 

under the shifter there's a black screw type thing does that twist or pull down to loosen the cable

Inline adjusters twist. Sometimes you need to lightly grip the narrower part to stop it twisting too. Turn it one way and the adjuster will extend; turn it the other and it will shorten. Be aware that turning to full extension can result in the two halves separating. No great problem but be aware. Have a look here: https://youtu.be/2zUhwdXj7wc

You may also have a barrel adjuster on the frame; again adjust this so that it is not fully extended. Screw it all the way in, and then back out 1 to 1.5 turns to give you some cable adjustment either way once the inner is secured.

Good luck.

It was a brand new cable only got it out of service today 

my plan was too move the derailer slightly up and then do the indexing 

so I detached the cable and moved it , but then was like 1cm short from getting the cable back on then moved the derailer back to the original position and still can't get the cable back on

Really tricky job on brifters - probably not within the OP's capabilities (sorry OP)

In my experience gear cables are easier to do on brifters than brake cables, as long as your outers have been finished cleanly and it's a brand new cable. Oddly enough I have bigger issues doing gear cables on the old style straight-through style where your outers aren't under the bar tape.

Just use a brand new cable and follow Shimano's instructions. Same goes for front mech, don't be intimidated by it.
