Any tips on how to perform tricks like an infinity roll on a unicycle.
I always find that my knees get in the way which is painful if the devil stick is on fire
Thanks,
I think it would be rare to find another unicyclist that does devil sticks while on a unicycle. I think I did it once at circus school except the devil sticks were not on fire. It’s just keeping your balance really so you can perform the devil stick tricks. As for the problem of them hitting your legs when it’s on fire I can’t really help unless you wear thick clothing? 
EDIT: If the devil stick is not on fire and it is hitting your legs, maybe try raising the height of your seat post so you can avoid your knees being too close to the sticks.
