I bought the Castelli CX 2.0 Speedsuit for cool to moderately cold weather layering. Despite its cyclocross branding, it’s perfectly acceptable for road use as well, with a sleek simple design and what so far seems to be a very nice chamois that will endure way longer than any pro CX race.
I got the blue/black/red design because I’m just such a sucker for blue. It’s a really beautiful color and the stripes down the sleeve are very sharp. All the material has a bit of a sheen to it, more so than some lycra you see, though it fades as the material stretches. The Castelli branding down the side panel of the legs is a bit much, but elsewhere it’s pretty minimal and tasteful. Print quality, stitching, and overall fit and finish is excellent. The fleece lined lycra upper body/sleeves are warmer than regular lycra but still breathable. It’s not a wind blocking fabric and it’s still kind of thin, so it’s not crazy warm. The lower body is regular non-fleece lycra but it’s a decent weight fabric. If you want a warmer suit with fleece lined bottoms get the Santini DirtShell. I can’t say the design/cut of the rear and the shape of the chamois is particularly flattering to those looking at your behind, but to each his own. There’s a nice lighter weight textured fabric under the armpits for better ventilation. It looks like the same fabric Cuore uses on many of their aero skinsuits and jersey sleeves, but you barely notice it.
The zipper seems fine, though it was a bit hard to manhandle the thing up with some belly trying to push through. Despite that, once zipped the cut of the shorts is high enough that you don’t feel like your gut is going to come pouring out between the top and bottom of the suit, and it’s still much much easier to take a nature break than in a traditional skinsuit. The leg grippers are like those on most other Castelli shorts, with a textured fabric, tight flatlock stitching, and no hem at the leg opening. The edge is very crisp, better than I’ve seen from most other clothing manufacturers, and doesn’t look like it will curl over time. The sleeves have 1 1/2” long hems/cuffs around the wrist, giving it a somewhat retro look, but it’s also very comfortable and stays in place. This suit technically has a mock turtleneck, but it’s just low enough that it doesn’t feel like it’s choking you, and even without a wind flap the zipper doesn’t dig into your neck. There’s two very deep pockets in the back, great for storing anything, and they stay tight and aero when not used too.
The chamois, after the first one-hour ride, feels awesome. It’s dense and supportive and shaped just right. Even without chamois cream it felt like nothing was there. Time will tell how it does on longer rides, but first impressions are good. Usually if a chamois isn’t too great, I’ll know within about a half hour. Sizing is typical for Castelli, which is pretty small/Euro. I’m 6’-3” 275 lbs (it’s not all muscle sadly), and even 3XL is a bit tight. The way the jersey top opens all the way, as I mentioned above, makes zipping up difficult. The fabric also lightens noticeably when stretched, a common problem with Castelli gear. Sleek shiny jet black fabric turns to matte charcoal if it’s stretched at all. That said, the leg grippers, sleeves, and waist all feel evenly form-fitting, so there’s nothing pinching or uncomfortably tight, so it still fits pretty well.
The Castelli CX 2.0 Speedsuit is a very good skinsuit for cyclocross or other cool weather layering. At full price, yeah it’s rather expensive. If it’s on sale for less than $200 then I’d say go for it.
