Rear wheel built w/ 262/264 Spokes - rebuild with single lengthfor both sides?

I'm replacing all the spokes on my rear mtb wheel - Sun SoS rim on a Specialized Enduro(if that sheds any light). The factory build used 262mm on the drive side and 264mm on the non-drive side. Is there a single length spoke I could use for both sides?

If you could find them then that would obviously be 263mm spokes. But you then risk not having enough engagement on the non drive side and suffering from longevity issues or you risk having too much engagement on the drive side and the nipples running into the ends of the threading and having durability issues due to not being able to achieve the correct tension.

It's not a big deal to buy the correct sizes and do the job right.

Proper length spoke comes right up to the slot in the head of the spoke nipple..
now if you have a longer axle on the left side + dropout spread..
so as the hub shell re-centers itself flanges equally distant from the center line ,
then you can have equal length, and balanced tension ..

Then again , that is part of the durability Of Internal gear hubs and single speed hub wheels ..
I think Phil Wood made some rear hubs larger left flange to use same spoke length
for both sides of rear and the 2 on the front.


then again, ''//,,
My wheel build on a [limited production] Campag Hi/Lo rear hub accentuated the differences , laced the small flange left with a 4 cross pattern
High flange right is a 3 cross, still holds it's true 20 years later..

Always use as close to the correct length spokes as possible. In my experience, it makes dishing easier. Besides that, it reduces the risk of getting a spoke too long or too short.

uses 262mm spokes, but use 14mm nipple for the long side and 12mm nipples for the short side.

This is a cool idea.

Thanks for the replies all.

Got my wheel rebuilt this evening using 262mm and 264mm Wheelsmith 2.0mm/1.7mm butted spokes and the regular 12mm nipples. Hit up an LBS for this. Used boiled linseed oil for the prep. Went with silver for both the spokes and nipples but kinda miss the black spokes on there... not that that affects the ride anyways. While I was truing this wheel, I kept chasing the same few wiggles and realized the rim has a few minor flat spots. Not sure when I 'put' those there. Will have to replace this rim eventually with something a bit beefier but for now it's not noticeable.

Made me think about my past bikes and how long I rode those without putting those wheels in a truing stand to note any issues. Ignorance is bliss I guess.

Thanks again for the replies.

I thought this was frowned upon by wheelbuilders since it leaves the thin section of the nipple un-supported where it passes through the rim? Brass nipples aren't as strong as the SS spoke, so unless there is a spoke threading through this thin section, the nipple may fail after some time at that spot.

It sounds like a "nifty" idea, but realize that you're probably not going to be doing it the "right" way.

Why did you replace the original spokes? The ones you used are top notch.
