Good idea, I hadn't thought of that.
Crossed spoke lengths are quite sensitive to skipping holes; radial spokes are less sensitive.
On your 32 hole hub, crossing the 8 left spokes might be easier to calculate, given the even spacing. Then radial on the right side. You'd want a stout shell to transfer the torque. Right side heads in or out? I guess it depends on the flange location, to clear the RD. Might be interesting whether heads in would clear - it might, given many (not all) hub flanges must also work with a spoke protector...

Not much radical, but De Rosa trying something funny with their new Metamorphosis http://www.derosanews.com/en/2018/06/27/metamorphosis/

Well, I was going to say some iterations of beam bike frame, then I found this:
It's art, literally.

That is awesome, but the cross wind must be a nightmare

Yes it is awesome, but I notice it looks like a track bike.
Maybe only ride it on indoor velodromes?

Curious if the fully enclosed rear wheel doesn’t have a negative effect linked to the air trapped around the wheel. On race cars the turbulences in the wheel arches are a serious problem the engineers try to overcome for decades.DamonRinard wrote:Yes it is awesome, but I notice it looks like a track bike.

Indeed, the geometry is absolutely extreme to be as close as possible from the derny then use the aspiration as much as possible, explains the small wheel, the fork geometry and the weird reinforcement to support a position such much “in front”Dan512 wrote:Or this, no clue if there is an english name. We call them « Steher ». It’s a type of track race behing a motorbike.
The speeds they ride at are incredible (just check out the gearing)

I just googled it. Speeds above 100 km/h. The races can last up to 24 hours.
