Schlumpf Tips & Advice

I’m pretty sure they’re empty on mine but I’d have to pull off the disc to find out for sure.

Shift gears. One side carries all the load in high gear - that’s where the small pin comes in to play. I wonder if that’s what you’re describing.

I’m aware of the pin on the bearing holder — I drilled a hole for it, and it’s securely in place. But in my case, this is what’s happening, and it clearly shouldn’t be rotating like that. I most likely lost the three small screws.

You’re definitely missing the 3 screws. I don’t know their specs though :frowning:
You should drop an email to Florian. He may help you.

Is that a Flansberrium V-frame? :face_with_monocle:
I mean: That is a Flansberrium V-frame!

Maybe I can remove the disc of my Schlumpf to check the screw dimensions tomorrow or the day after tomorrow. I should shim the disc anyway, so I can use it in different frames.

How much force should it take to shift the gears? I don’t know if I got a dud, or I’m just at the “it can’t be me, it’s the equipment” phase of learning, but it seems unreasonable high, especially the upshift. I measured 26 shifts up and down with a postal scale, and upshifting averaged 4.2 kg, and the downshifts averaged 3.6 kg. The maximum shift forces were 4.4 kg up and 4.1 down. Is that typical?

Edit: lol it was me, not the equipment. Ankle shifting ftw. For future Schlumpf strugglers, here’s what worked for me. I dropped my seat 1 cm, and adjusted each button so the bottom edge was flush with the crank surface. To make ankle shifting work with my low top 5.10 freeriders, I wore ankle guards ($10 from Amazon) secured firmly in place with duct tape.

Recently, I had the opportunity to borrow a G29 from a friend for a few weeks. My only experience with a geared unicycle was with a G26, which I borrowed several times during Unicon21, but I didn’t try the gear shifting then.
Before trying the G29 for the first time, I read discussions, including this thread, and watched videos, which made me feel a bit anxious, particularly about the gear shifting.

In practice, I first held onto the railings at the roller rink to get used to it. After that, I rode in circles, went back and forth, practiced shifting gears, and eventually rode along a bike trail for about 7km. I found that shifting gears at low speeds wasn’t as tricky as I had feared. By intentionally pushing my heels inward while pedaling, I could easily engage the button and shift gears successfully. However, downshifting at certain speeds was a bit intimidating. As for riding at higher speeds, I struggled because I was still unfamiliar with the high gears. Furthermore, the 150mm crank length felt too long, making it difficult for me to pedal quickly, so I ended up going slower than when I rode a regular 36er. ![20250521_204953|500x500](upload://x3LAhJVu54TKneKIJlmSaOoRfPp.jpeg)

I just swapped my old ragged fiveten freeriders for a pair of the Leatt Flat 1.0 Hi shoes and the difference is night and day. I’m hitting my shifts on the first try 9 times out of ten, and they look way cooler than the freeriders. I wish they were a little stiffer, but that aside, I can’t recommend them enough

I wish we had a roller ring. It is great for learning to ride UW
