FS: Powertap SL - SOLD

Is it built up to a wheel or just the hub? If built into a wheel, what wheel?

Thanks.

It was built into a cheap Alexrims wheel, but I’ve sinced removed it; so the price is only for the hub.

How many miles on the hub?

There’s about 150 miles on the hub and they were all on the trainer.
