20H 12-8 lacing

[WinterRider]

Torsional stiffness is not affected by hub flange to centre spacing. It is affected by how close to the tangent of the hub flange the spokes are. Spoke count and spoke guage are relevant. Flange pcd is too.

Doing heads in lacing will not improve torque transfer. The bends in the spokes are severe too and are a potential weakness hense why ergott used CX rays as that minimises the risk.

I imagine ergott did 1x ds heads in to improve lateral wheel stiffness and nds spoke tension on an oddball wheel where this was the least worst option, possibly with a rim that could not take much tension.

Figuring length's for crossing 12-8's can be done.. just not by me.

12-8 does nicely increase NDS tension w the lousy tension ratio's of many hubs.

Fact remains.. the wheel is very stiff. Crow's foot DS would give less consternation... might outlast many 12-12's.

It's just a matter of time before that hub breaks I think. But if you don't ride it it will last forever.

How did you measure that? What values did you get? How does that measurement compare with a control wheel of known durability?

Radial DS is a clown's game.

The hub body wasn't designed to take drive torque, and having only 4 spokes pulling on that small flange is crazy =0

If you can, calculate the forces a 1000w effort in a low gear will put on the drive spokes.

The rims look fantastic. What are they?

Another thing is that the spoke spacing is irregular. Won't it make the wheel very tricky to true? Just a matter of inconvenience so it's nothing major. But it could mean that truing the wheel is very time consuming and spoke tension is irregular even within each side. Every 3rd ds spoke is alone, or every second nds spoke has two neighboring ds spokes instead of one.

NDS: 3,5,8,10,13,15,18,20
DS: 1,2,4,6,7,9,11,12,14,16,17,19

Again.. LMAO. Laughter sure works... great way to start the day. Ah the keyboard queens...

Now does one measure wheel durability.. objectively? One rider's 10,000 miles are easier on on wheel than another's 1000K of climbing and sprinting... IE: relative rider strength vs load/riding style.

'Parlor games' wheel measuring... setting wts on stationary wheels et al.. more nonsense. The fella that made the floppy wheel spokes a few yrs back surely proved that.

IF one wanted to refine this 'available parts on hand' lacing.. going clockwise from the valve.. DS's1-4, 5-8, 9-12 cross. Move either radial spoke one inside.

Maybe then the hysterics could forgo their valium.

You are making claims that you call facts.

I say you don't know what you're talking about.

Ball's in your court.
