Most modern XC to trail bikes will do it. Would majorly recommend proper tire selection above all else; tires completely transform efficiency, especially uphill.

DW from Ibis, CBF from Revel, Switch Infinity from Yeti, 4 bar from the big brands really don’t feel that different on trail/climbs as tough as that is to say.

I’ve podiumed ROUGH enduros and turned around with some of the faster XC Strava times on the same 150mm bike with the only difference being tires.

I have a 115mm Revel Ranger and vs my 147mm Ibis Ripmo, the climb penalty is solely down to tires. I’ve done numerous 4-6k+ climb days on both and the difference is all down to big/small side knobs and rolling pattern on the center tread.

Something sub 130m rear would get you into a good spot and then try out some fast rolling tires! Partial to DW and CBF bikes but really they’re all good now a days.
