For those that are running CFR bars on their sleds, what are you using for a mtn strap? I want to put one on mine but don't want to use the CFR mtn strap and would prefer to use the Doo strap if at all possible. Anyone know what size the handlebars are on a 2021 SP? Also, has anyone managed to seperate the thumb warmer from the hand warmers, I prefer to run my thumb warmer cooler that my hand warmers.
