Buying spokes?

[Neil]

Used an online spoke calculator here to get the length of spokes I'd need to build up a Sun / Avenir Duro 17 32h rim to a rear Deore DX hub, and it spits out:-

left spoke length: 266.1
right spoke length: 264.4

With those lengths do you round up or down when buying spokes?

i would buy 266 & 265 spokes. But i'm just a beginner

Well where I've seen them online, they've been in 264 or 266 lengths (others too, just those are the closest to the lengths I need).

I used that very same calculator, but noticed it had Mavic 230 rims as 546ERD when they say 559ERD on the rim :?

I had that problem so went for longer

I buy bulk spokes @ 300mm and cut and thread them myself, but if you go longer it might not be to bad. problem with longer is they may stick out the top of the nipple.

what did you use to calculate the lengths? Try an Excel file called spocalc.xls it has a list or rims and hubs and the numbers needed to do the calc. spoke pattern will also dictate the length.

230s are 546 ERD. 559 is the wheel size. I really can't think of any kind way of suggesting why Mavic put the wheel size there instead of the ERD, which would actually be helpful.

People often suggest rounding up rather than down, but since odd lengths are harder to get hold of, I doubt whether rounding down by 0.4mm is going to do any harm.

Thanks for that, should have realised, but ive only ever seen erd's printed there so assumed the same with these rims.
