Nextie 36" carbon rim

Straight spokes from UDC is as far as I know still the only option, unless you want to fulfil a minimum order with Berd.

I do wonder whether some of the larger spoke manufacturers would do longer double butted spokes for a reasonable minimum order. Ideally they’d probably be as long as a 36" rim could ever require, then UDC (or others) could cut and roll them shorter to the length required.
