I’d like to open a thread to record all the things I think worth sharing when riding my newly built G26, from the perspective of someone new to the Schlumpf hub.
Mods: please let me know if this is too much fragmentation.
I know there are several threads/megathreads about the Schlumpf hub, I’d be happy to move my posts to one of the general discussion threads.
I started unicycling from July, 2022. I’m a slow learner, it took me about 15 hours to be able to ride unassisted; but I ride a lot. Currently (February 2023) I commute daily on a KH26 (/w Schlumpf hub), and occasionally ride longer distance on an Oracle 36.
I had the opportunity to get a Gen4 (M08xx) Schlumpf hub, so I decided to build a wheel around it. See this post for details.
I read many topics about the Schlumpf hub in our forum, grabbed the impression that it’s a sophisticated device that’s quite difficult to master.
The wheel is built, I got it set up on my KH26. An instant fit, not much trouble.
Tried to ride on low gear: same as fixed mode, no problem at all.
Tried to freemount on high gear: NO WAY… at all. Not today.
Tried to ride on high gear, with assisted mount: it feels very hard in the beginning. When I push the pedal, the wheel does not respond instantly as in fixed mode, instead there is a slight delay. This is rather counter-intuitive, took me several attempts to finally get it running. The delay effect is more significant when accelerating (or decelerating), but when riding in a constant speed, it’s less bothering.
Riding on high gear is quite funky. I got many of the old terrifying feelings back, dated back to when I started to learn unicycling. Legs are stressed, I couldn’t have my butt sit tight. I was too afraid to grab the handle bar. The speed is like a 36er, but the wheel feels much heavier, and it’s way less stable than a 36er. When dismounting the wheel has so much inertia that it almost fly away from my hand. After several UPDs, the ride is slowly becoming more manageable.
Riding on low gear after that is funny: I just can’t ride it. Not after a few attempts. My legs are used to the high gear, now they put too much force on the pedals, which leads to an instant UPD. This is also a thing that I have to overcome before I can actually shift from high gear to low gear on the fly.
Shifting seems difficult. I can’t ride one footer, and my studded pedals are very grippy, it’s hard to move my feet. That being said, I had an accidental shift which ended up with a UPD. Will try this another day.
Rode back home on high gear, got 15.2km/h on average. Not very fast by my standard, as I can ride as fast in fixed mode (with crazy cadence tho), but surely I’ll get better.
Oops, I haven’t realized my pedals are still on the 127mm holes until I got home. Guess the 150mm holes will give me a smoother learning curve. Will change them next time.
That’s all for day 1! I’ll get back if I have more progress.
