Can anyone tell me of spoke suppliers for the the Crown / TC motor bought to length? I haven't found anywhere that supplies for 28" wheels, Crystalyte only have 26" and smaller.
The Crown / TC motor spokes?

TC motors are not so happy in a large wheel. That is probably the reason why they don't supply spoke length for larger than 26". Then, if your bike frame can clear big tires, you can achieve a 28" OD wheel with a 26" rim, using tires 2.5 and up.

how about using straight pull spokes..
& making your own spoke bends at custom angle as needed..

I had vaguely thought of this but haven't seen straight bike spokes. I'll have a look, I've got some spokes to try the bend but the bend is very close to the mushroom end so may not be too easy to bend accurately.
Thanks!

Straight pull spokes are not entirely uncommon for bicycles. Second most popular to 90deg J-bend, but it just happens to be an extremely distant second in popularity. The big guns for premium spokes Sapim and DT both make them in 14G and thinner:

For thick motorbike/dirtbike/pitbike/scooter end of things, bends other than 90deg or straight pull are also common:

The trouble is, they're generally too thick for getting adequate tension in bicycle rims, manufactured too short for a big bicycle wheel and not likely to be found in Crystalyte's specific 26deg bend.
Making your own bend might work out OK but might not. The way the Crown's spoke slots are set up, the wheelbuild has to be done carefully and everything must line up exactly or spokes will start popping back out of the hub shell when you least want them to!

Actually I think it would help if they go with a larger diameter rim. I had mine in 26 inch and the bend on those cause a few spoke to break. It was probably due to the chinese quality, but then again I don't think it was helping having them on such small diameter rims. With larger rims, or at least rims with proper angles on the nipples, you can actually do fine.

Aren't the spokes smaller gauge on the TC than those used on the 5300, 5400 etc. favoured by Crystalyte? Would this be a factor?mvly said:

ok, I just tried with a few 'normal' spokes that I'd replaced a week ago where they had snapped on the bend and it was really easy when gripped in a one of those small hobby vices even with the fairly short length to grip. So all I'd need to do is drill small countersinks at the position of the retaining flange thing so it doesn't get squashed in the vice, it's not much of a bend so it shouldn't need any heat treatment - I doubt it will be much more brittle through cold working it but that will be seen pretty quickly if it is a problem and can be easily sorted.
