Hello Dave climbs fine. It’ll never climb like an XC bike but for the type of bike it is it’s perfectly ok. You’ve just got to remember it’s a big,slack,long,heavy frame but an absolute riot when pointed downhill. The steep seat tube angle helps with the climbing ability because it puts your weight more central on the bike. For context I love Hardcore hardtails and over the last few years I’ve had 2 Chromag Rootdowns, a Nordest Bardino, A Dartmoor Hornet and my last 26 inch bike was an Evil Soverign. I wouldn’t say my current Helo Dave climbs worse than any of them.
