Half radial rear wheel

non-drive side makes more sense....0

http://spokeanwheel.110mb.com/lacingsr.htm#hrA properly built half radial rear wheel will be radially laced on the drive side. It would also be best to lace the drive side so the spoke heads are on the inside of the flange.0

I have read that before, and I have read Sheldon Brown's wheelbuilding article and he claims that it should be on the non-drive side.0 -
hmmm, Sheldon is completely contradictory to the link I posted. And having done some thinking over lunchtime, the spokeandwheel site contradicts itself between the half radial section and the 2x/3x lacing section below it where it saysA mixed lacing pattern I discovered that works very well for balancing rear wheel lateral strengths is the 2-cross/3-cross lacing. This pattern uses 2-cross lacing on the non drive side and 3-cross lacing on the drive side. The non drive side spokes end up being shorter than the drive side spokes, a condition that causes theoretical force vector triangles that counteracts the dish offset of the wheel. This theoretical triangle is comprised of the real force vectors of the spokes and a theoretical force vector across the hub.
In that example, the shorter (2x) spokes are NDS, so following this logic if you were to build a half radial/2x the radial should be NDS.
I've built a 3x/2x DS/NDS wheel and it's been fine but never tried half radial so have no practical experience.
Maybe the wheelbuilding guru that is Roger Musson can comment on this? I know he posts on here sometimes.0 -
Well my Mavic Aksium is radial on the non drive side yet my Mavic Ksyrium is radial on the drive side!
Kind of suggests it doesn't really matter (so long as it's not both!)0 -
Non drive side.Commute: Langster -Singlecross - Brompton S2-LX
Road: 95 Trek 5500 -Look 695 Aerolight eTap - Boardman TTe eTap
Offroad: Pace RC200 - Dawes Kickback 2 tandem - Tricross - Boardman CXR9.8 - Ridley x-fire0 -
i think the theory for drive side radial is to use the less tensioned spokes on the non drive side to do the driving force thus the higher tensioned dish side doesnt have additional strain. the drive is transmitted equally to both hub flanges so the fact the chain is on the radial side doesnt really matter. also the dished side benefits from greated latter stifness being radial which is lower that side.0
