Choosing the right compound and casings
MoPo Compound - Softest compound 42a, has excellent damping characteristics and reaps traction in wet slimy conditions
Control - Balance of MoPo compound with more durability and efficiency, still excellent grip in the wet
Endurance Compound - Not as soft as the MoPo but does extend durability with a 50a/56a dual compound. If are killing your tyres in a few rides, the Endurance is probably the better choice.
Trail Casing - 72TPI single poly, tubeless insert with nylon breaker
Enduro Casing- Dual ply, 120TPI with full nylon break.
