that said, off the rack bikes with threadless forks, especially a full carbon fork, often are limited in steerer length and/or how many spacers you can install and stay in the safe zone.
The Carbonomas (Carbonnomore?) fork that Riv sells would be the ticket. But I think, for 200$ and the other money I would have to spend to get a headset and then have a shop install it, I would rather save the dough towards my next Rivbike.
UPDATE:I commuted with the roadie today.
UPDATE:Got the hub back. Flipped bike. Put it on the bike. Pedalled a turn or two. Went to the bathroom to wash my hands. When I returned, the wheel was still moving. Now thats what I call a freed up hub.
