Just wanted to post my thoughts on my newest unicycle. I managed to acquire a KH36" with a Schlumpf hub and I’ve been riding it for about a month. I also own a normal ungeared KH36" on 110mm cranks which I can ride comfortably at 18km/hr or push it to about 25.
So far with the KH36" Guni I’m slowly learning how to change gears but it does take me a few revolutions sometimes to click the gear in for both up and downshifting. Sometimes I change gears and immediately UPD too. It’s strange going from riding relatively UPD free to having several in the course of a ride. Currently I’m much faster on my ungeared uni then my geared one.
I can get it to about 20km/hr on a ride in high gear but if I try to go faster I usually UPD and it’s hard to keep practicing at that speed as UPD’s going that fast can be hazardous but so far I’ve landed on my feet every time. I’m hoping I just need more time to fully get used to using this unicycle but the learning curve is pretty hard compared to other unicycles I’ve ridden. I think this is an earlier hub as it’s marked M122 on the hub.
Some positives I’ve noticed is downhill is surprisingly smooth and not sketchy as my ungeared uni as my legs are not spinning as fast. Not to mention with long cranks I can hop/idle to a degree and I’m so much more manoeuvrable with long cranks. Steep hills are easier with the longer cranks but smaller hills including most of the ones around my area I can ride up them faster with 110 cranks. At least mounting is so much easier with long cranks.
