Have run a 2.1 folding 60a tubed on the rear (35-40 psi) for 8 months and then converted to tubeless on flow rims with stans sealant for past 4 months (30 psi) …sizes up with reasonable volume but seems reasonably fast rolling and has been my general use tyre for everything except full on mud, when a 2.0 Bonty Mud-x comes out. Seems to be a good balance of roll and traction from dry through wet, and has worn reasonably well. I’m going to try a LUST crossmax 2.1 for hard packed trail and bridal way duties and lower rolling resistance though if summer ever arrives 🙄
On taking a closer look at the 60a, it actually says “maximum load 90kg” on the sidewall which I’ve never spotted before…..me + bike has been 100kg at least, but no problems with a years use.
Had the wired 70 version before that and that was a bit slippy on rocks/roots when things got wet…..but then again that was pre my tubeless conversion and I tended to default to 40 psi pressures….hard compound and higher pressures probably not optimal in the wet in hindsight! Tried running it reversed as suggested in various online places and it certainly grabbed and gripped more on braking, but wore faster also. Would recommend 60a over 70 to give more versatility from dry through to slippy wet/light mud.
