- Straight pull or J pull?
Dont know what you mean by time saving?
Only difference I found is its harder to build/true your wheel as the spokes tend to just spin. Also a more complicated – machined hub is required rather than just a simple flanged affair. I have a set but wouldn’t bother again.Posted 4 years agondthorntonMember
A set of straight pull – Yes I suppose they have been very good wheels once built – haven’t snapped a single spoke.
But they did take a lot longer to build into a wheel as tightening the nipple just resulted in spinning the spoke once tension was introduced – I ended up having to use mole grips to keep the spoke from spinning – and this made marks.
A J-spoke cant spin like this although is does build up tension instead – so you need to stress relieve but that’s easy.
Perhaps there is a special tool you can get for gripping the straight spokes – or perhaps it was because I was reusing spokes which had previously been thread locked (forgot about that)
For me though a flanged and drilled hub (J spoke) is a simpler design than a machined hub (straight pull)…..and my experience of simpler normally means stronger, cheaper, lighter etc.Posted 4 years agoPimpmaster JazzMember

For some reason the rim I was building (Stan’s) over-tensioned incredibly easily too. I too wouldn’t bother again. Spokes can be a pig to replace too, depending where they sit on the hub (the getting the nipple past other spokes to the spoke seat can be incredibly fiddley).Posted 4 years agomrmonkfingerMember
Straight pull offers nothing over regular elbowed spokes IMO, and are trickier to build (spinning).
Hubs to suit straight pull are weaker, more complex, and often more expensive.
Elbowed spokes every time.
I’ve heard J pull can be more subject to breakage due to tolerances of the “J”
Broken spokes are usually a sign of a crap wheel build with low tensions. Or a damaged wheel that has not been repaired.Posted 4 years agocynic-alMember

I’ve heard J pull can be more subject to breakage due to tolerances of the “J” and the hole in the hub – ie they move/are weak?
Been doing it that way for decades – SP has not been found to be significantly better.
joolsburger – Member Straight pull seems a solution for a problem that just doesn’t exist.
^ that – looks different/fancier, put a price premium on it and market it as “better”. plenty will buy it.Posted 4 years agomessiahMember
If the straight-pull was the norm and someone came up with a circular flange design that allows spokes with a J-bend at one end to be placed further out from the hub centre (hence building a stronger wheel) and doing away with those week and difficult to machine spoke holding turrets they would be onto a winning design…Posted 4 years agoshortcutSubscriber
J Bend is my prefered option. Easier to re-build or repair as spares are easier to source.
J Bend spokes break for the same reasons any spoke breaks. It was cheap, it was over tensioned, it was old and tired, it was poorly built or has been abused in some other way.Posted 4 years ago
