Maybe a stupid question but…

I have been given a set of 7700 shimano wheels, but one has a broken spoke, and needs a new nipple. The spoke that needs replaceing is the drive side (right) rear wheel, but the only 7700 nipples I can find are left hand nipples – does this refer to the thread direction and can I use it on the RHS?

Also anyone know where I can get hold of some drive side aero spokes for this wheel?

I think the nips are the same both sides so that should be fine. I think the spoke is a 4AM 9803 – nowt else will fit, you may struggle. Mister P is your man.

Cheers Njee, I’ll get that nipple ordered then, who is Mister P sorry?
