Hi, I can confirm the rocky road will happily take 2.6 on the rear, might even push to 2.8 if low tread profile. The front is massive, 2.8 to 3″ no bother. I’m running 2.8/2.6 on the original rims. Seems OK for my xc riding.

I bought a rocky road bike. Size medium, with 2.1 tyres and carbon bar. 10.3kg on the scales.
Sadly I’m adding to the weight by adding a 2.8 rekon on the front (tubeless of course), 2.6 ikon on the back and changing the bars to alkpit confusus. It’s to be an all out packing rig.

So far really impressed, though brakes really need an uplift.
