Hi,

I am having to upgrade my commuter/winter bike's wheelset (the wheels got stolen!), and was wondering what tyre width the frame can take. I googled around but can't seem to find any reference to clearance!

B'twin sold these up until 2016/17, as the "Mach 740" then as the "Mach 720" and they always came with 23mm as standard. Since they are fairly recent frames I assume they will take 25mm, but does anyone know if I could go even bigger? I have 23mm on my "main" road bike - and have always gone for 23mm, and wouldn't mind trying out what the fuss is with the wider tyres.

Would greatly appreciate any help or advice!
