I run a 36T oval against a 10-40 at the back (XT 10-36 with superstar components 40 XPR). I get up everything except loose rocks or boulders like some bridal ways in the lake district. Started my 1×10 with a 32T but wanted more ummmff
I chose a 36T for the power and speed, when you hit that sweet spot on a smooth climb, you can just push it hard and drop everyone. Control is fantastic on climbs too when you’re inching along and I dont spin out on roads. I recently bikepacked 100miles in the lakes but had a 25mile road ride first and clocked 16mph fully loaded. They say, the 36T oval gives you 38T power..
Schurter runs the 38t as he loves to drop everyone, the power he’s got is immense and unless he’s tired Absalon, who runs 32-34, can’t chase. Remember Albstadt last year, absalon is spinning like crazy to the line, but Schurter inches past him grinding the bigger cog=win.
