Having trouble with spoke lengths.

I'm building my first wheelset but my usual supplier doesn't stock suitable spokes in 299mm or 297mm for this build, only lengths in multiples of 2. What would my options be? I was recommended these sizes by the supplier:

32h 3x -

Front:

Left spoke length: 299

Right spoke length: 299

Rear:

Left spoke length: 298

Right spoke length: 296/297

EDIT: Apologies, here's the parts in question:

Spokes: DT Swiss Champion 2,0

Rims: Mavic Open Elite

Hubs: Shimano Tiagra RS400

I was considering rounding up 300 all round, and then 298 for the rear drive side but I'm not sure if that will work. Another idea was going 298 all round and then possibly 296 rear drive side. Very confused at the moment.

Any suggestions appreciated, thanks!

R

Who measured everything? We need to know if the measurements were 'generous' or 'tight' before deciding which way to go.

Why would you choose 298 for the drive side?

Which brand spoke are you seeking?

Some shops have spoke cutting machines and can cut to the exact length you want.

DansComp.com will cut to any length as well.

296 rear DS.
298 all others.

Do some more measuring.
Some spoke brands are on the short side.
Don't take my word for anything.

What hub & rim?
What spoke length calculator?

Many of us use our favorite calculator and then round up/down, based on previous experience.

If a double wall rim, I tend to favor long. If a single wall, I don't favor long.

Word.




And I agree with davidad - if you're going to both building decent wheels, pop for butted spokes. You'll just feel like a cheapskate later if you don't, and they will ride better and possibly last longer.

There are E-Bay sellers that cut and thread spokes to length with reasonable prices.

How did you measure your ERD? To top of the nipple head? Are you using nipple washers? Measured?

Spokes can stretch slightly, so if your measurements are on the long size, I'd round down as above.

And, stocking just 2 spoke sizes will help if you carry spares on a tour or something.

I'm no wheel building guru, but I can't see that 1mm is going to matter.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

Cheers, that would actually be quite convenient as I have some 296mm around somewhere.
