I can't tell, is this frame raw alu or painted in some way? I love the darker grey and am not sure if its due to the lighting or some paint.

That frame was painted. I sold it raw, and he had it painted on his own. The color is very nice! I'd like to see in person to know what it really looks like!

Just got my 27.5 built up! Currently at 4.42kg/9.76lbs but I have a couple of bolts and small pieces to swap out that will drop it to around 4.35!

Looks Pretty Bad!

Those cranks are nuts. How many holes are drilled in there? Do you think they will hold up? I've seen ventures snap without being drilled.

Wennn · 2017-09-28, 03:18 AM

Heh, those cranks were drilled about half a year ago and they seem to be holding up fine for now. The holes aren't really for weight savings, they are tapped so I can change my pedal length anywhere from 30 to 150mm!

I don't own a drill press so those cranks were drilled by eye and some holes are a little tilted. I'm still looking around for one so I can get my new set of cranks drilled the same way.

Riding Muni with 30mm crank length is impressive

UniDreamerFR · 2017-09-28, 08:55 AM

I don't even know if it's possible to ride it with 30mm cranks, but let's say it's ok.
There is something that sounds like an issue to me with this huge 30-150mm range: the seatpost/frame neck.

let's imagine the pedals are on the 150mm position, the seatpost touching the bottom of the frame (best scenario for what's following).

now you want to movet the pedals on the 30mm position, if you want to keep the same knee degree at the low pedal position you have to raise the saddle up 4" to 5" higher, but then there is just a bit of the seatpost left inside the frame, which makes it weak.

Now let's imagine you barely move the saddle's height when changing from 30 to 150, then you'll have the legs straight on the muni/trial mode (150s) and the legs flexed on the fast spinning/cruising mode (30s), which is also weird cause you rather want the contrary of that.

Do you have several sets of saddle+seatpost depending on which crank hole you want to use?
maybe I am completely wrong.

Definitely going to experiment with this on the G29 for the next road race

Wennn · 2017-10-01, 07:03 AM

The seatpost adjustment range means I can use the it within the 70-150 range (accounting for the straighter legs wanted at 70). I typically use the 90s for road, 110 on cross country and 150 for offroad. It looked weird in the sketches with those holes drilled so I decided to drill the rest anyway.

Edit: To be clear, I have never actually rode with the 30 holes, only for spinning the wheel fast to bed in the disc brake. I've tried 50 just for the fun of it on my nimbus road 29 and while it was rideable in a sense, it was much slower than the 70s which were slower than the 90s (for my skill level at that point of time) even on a flat level track. 70s could climb surprisingly decent hills, but at an immense energy cost.

Sharing some photos of my new gravel unicycle: Flansberrium 700C. Thanks Jakob for an awesome job with the frame and handlebar!

That skinny 700c frame looks SWEET!

Is that a carbon wheel too? And what tyre width?

That looks amazing! Thank you soo much for sharing!

Those machined cutaway areas on the frame are pretty cool, is that something new?

They probably don't save much weight but the bling factor is super high!
