Well, I talked to my regular mechanic, and he will build me a set of Ultegra/Dyads for about $40 more than Universal, so the price would be very close considering I won't have to pay shipping. He can get the silver rims, so I am good to go. I have heard conflicting information on whether the lack of machined rims on the Synergys would be an issue, so I went with my mechanic's advice. He thought I should get the Dyads since they are machined. His reasoning is that 99% of the quality bike rims these days have machined rims for bikes with caliper or canti brakes, so they must do it for a reason. I tend to agree. The Dyads are also lighter than the Synergys but considered stronger.
I am going to put Continental GP 4 Season 28s on the rims. I am trying to keep the wheels as light as possible since it is very hilly where I ride.
