Thanks for the info everyone, very helpful.
My rims are Mavic 729 and aren’t tubeless compatible :/ I plan to change to Stans Flow sooner or later and save another 200+ on rim weight.
I currently ride Thetford forest, the trails are dry and water drains easily. I want to move onto bigger things like Chicksands and Phoenix, but breaking my arm 3 weeks ago has pushed that back a little.
I’m going to try the Ralph and the Rock Razor. I’m keen to learn the real world differences between tyres.
