I switched over to 559's on my XStream and haven't looked back...I'm very pleased with them. If your Xstream is like mine, the brake pad mounts have slotted holes in them so they'll work with either a 559 or a 650 wheel. The rolling diameters are much the same between the two sizes - the 559 rim is a little smaller in diameter, which allows for more tire section height. I used a Velocity Synergy Offset rim with 32 spokes for the back wheel. On the front I used regular Velocity Synergy rim, also with 32 spokes. My normal setup is 85 psi rear and 70 psi front for a nice comfy ride. If I want to go as fast as I can go, I up the pressure to 100 psi in both tires. If my new setup is any heavier than the factory 650's, I can't tell it (I never did weight either wheel). They sure do ride smooth. I've been running these wheels since last September, and they still run incredibly true and smooth. If I were a weight weenie, I might have done something different...like choose a lighter wheelset, and diet 35 lbs off of the pilot. I have an aero belly, so I should be faster than Jay... but I'm not. What's up with that? PS...If anybody wants the 650 wheels that came on my XStream, I'll make them a very good price.
