Hi, I realise that this is a bit anal but does anyone know if Superstar and Uberbike colours match? I’m mainly looking at red...

Cheers

I don't know about that, but I do know uber bikes green does not match the green from the ' made in the UK' range they have. I got jockey wheels and chain ring bolts both in green and they are fairly different.

Not gonna lie I didnt realise there were different thread pitches! I've just shot commencal an email to check which one I need (Their customer service is amazing btw) I'll do some googling for the mrp ones, cheers for your help

Based on my experience I believe there are 2 broad standards.

Syntace uses a finer pitch thread (I think 1mm) and has a cone shaped collet at the head end. I have only come across these in one length (Our Cubes use this types).

Shimano/Maxle uses a courser thread (1.75mm) and the head end is flat. These come in different lengths for the main axle and the thread. It needs to be long enough for the thread to be in the nut part but not on the wheel bearing. This fits my Ibis Mojo but the overall length matches yours. He does a range of different sizes.

Im also planning on doing a caliper service on my Sram brakes, Ive got some old dot fluid to clean the pistons with but its been sitting around for so long its probably taken on a tonne of water. Will this cause any issues even though I'll just be scrubbing the pistons with a tiny bit of it?

Have you got a link to their website with a spec list and that?

Can I upgrade the star ratchets on dt swiss 370 hubs? Funny the lack of engagement never bothered my on climbs but did a fast xc ride today and was out of the saddle hammering on and off and it was driving me nuts.

iirc 370s use a 3 pawl system. can be upgraded to use star ratchet, but not stock.

So is it as easy as dropping in the spacer two star ratchets with a spring on either side or is there modifications required?

no. You will need a new drive ring, the star ratchets, and a new freehub body. Best of you have a donor 350 or 240 hub to steal parts from.
