Bought a set of 55mm 'Fast and Light"…
Bought a set of 55mm 'Fast and Light" clinchers with 350 DT swiss hubs as training/racing wheels for the upcoming Tri season. Easy to order, faster than expected shipping. I put Conti GP 4000s on them- 23mm on the front, 25mm on the back, and there was lots of room in the rear wheel cavity of my Cervelo S2. These rims are extra wide, so I had to adjust my FSA calipers to their max to accept these wheels. These rims are a VERY tight fit with the conti's- I'd suggest going with another brand. I had to warm up my tires in the dryer before fitting them, and even after that, it still took 30 minutes per tire. I'm hoping the tires will wear and stretch so replacing a flat will get easier- right now, if I have a flat in a race, there is no chance I'm getting the tire back on. Wheels were true when I got them, and still are after 500 km. Really enjoy the DT Swiss hubs- very quiet when freewheeling, unlike just about any other carbons I've seen/heard at races. I've put two centuries into these wheels, and they definitely make the bike faster, as climbing is noticeably easier than on my stock shimanos. With that said, I'm not sure how much benefit is from the carbon, and how much is from the upgraded hubs (likely a combination of both). One note of caution- I could have maybe gone with the 50mm, as I find I'm getting blown around in the wind a lot more than before. This certainly isn't a result of ican's production, though, just deeper rims being deeper rims. Overall, love the feel, the benefits, the look, and the quality. I'm not sure how long they'll stand up, but they have a two-year warranty, and certainly didn't hurt the pocket book like any North-american wheels I looked at. Would easily give 5/5 if not for the super tight fit on the tire.
