sales@light-bicycle.com My rear hub is a 32 hole 2010 Powertap Elite. They sent me 251mm spokes and I had to have them cut and rolled at a local shop so they would fit ($10). Nancy credited the full value of the spokes for the error. I would confirm with her that they can supply the lengths you need if you don't go with a pre-built wheel. Here are the specs from my order.
Front Wheel:
- 50mm, 20 spokes, clincher, external nipples, 3k, matte finish, with basalt braking surface
- 20 spokes,black
- 20 nipples,red
- Novatec hub, black
Rear Wheel (built by customer):
- 50mm, 32 holes, clincher, for external nipples, 544 ERD, 3k, matte finish, with basalt braking surface

- 18 spokes 248mm, black
- 36 nipples, red
- Novatec hub, black
