2013 model. Not sure on the sizing I require. Can I go 142×12 or no bigger than 135×12? Hope pro 4 or Shimano XT hubs?

Standard 135×10.

Nothing to add but hello Martin.
You going to SSUK this year?

Pardon my ignorance but is bolt through not a step down from QR? Are you recommending it because it can give a stiffer wheel build?

standard rear hub that has been used for years. 135mm qr! (that means 10mm)

I was looking at Hope hubs and they only seem available in 10mm as a bolt through option? Will 135×12 do?

It won’t do if the frame is designed for a standard 135×10 hub.

I was looking at Hope hubs and they only seem available in 10mm as a bolt through option?

They’re available as qr

You sure you’ve bought the right frame?
You seem a bit confused about things.

Yup pretty confused. My old rear hub cracked and I just want to replace it. Myriad of options to choose from and I don’t know what I need as the said wheel was from another bike that just fitted. No idea what size it was etc. From the posts I need a 135x10qr?

Yes, thats the one.

Hi Stu, Being a lazy bastard and staying at home this. I must be getting old.

From the posts I need a 135x10qr?

Yep.

Fantastic cheers. Now I know what hub I require. What rim width do I need? Looking at Arc+ 45 or WTB Scraper 45 rim. Be running 2.4/2.5 tyres. Do I need to go narrower?

I have a 35mm rim on mine which is great for tyrss such as an Ikon 2.35 or Ardent 2.4

Do I need to go narrower?

Not really, I’d go wide as you can, the bike suits it. I have P35 / 30mm internal width rims and would go wider on my next wheelset. 30-35mm is good though, tyre looks bigger but still has a normal profile. Mud clearance at the back with 2.4 Ardents on P35s is ok but not huge.

Got 50mm rims on mine have run both 2.35 Ikon and 2.4 Ardent.
