Also have an 04 Speedster with a Wound Up CF fork - but it is a disc fork now - as I upgraded a few years ago. When I purchased the bike - the Rolf wheels were a relatively inexpensive upgrade through Co-Mo so I went with a set. I've had my share of problems with spoke breakage and rims cracking and I'm on my second set as I bought a new set in 2010. After my last rim failure I purchased a set handmade of 32 spoke wheels w/ db Sapim round spokes and brass nipples laced to Kinlin 29 rims and WI6 disc hubs. They are only slightly heavier than the Rolfs and I like them SO much more. The hub to fork interface is better - as the WI6's have a larger axle caps which mate better with the fork in the front and dropouts in the rear. I'm able to run less psi in the tires - although only 5 psi less - the ride is more forgiving. Then on top of that they are stiffer laterally when climbing out of the saddle. Lastly - if a rim does crack - I don't have to send the hub back to Rolf and have them replace the spokes, nipples and rim at a cost of more than the new wheel would cost me to build.
