I got this singlet for the cool morning rides (60-70 deg), but I've continued to wear it in temps up to the low-80s. Gore's sizing chart worked perfectly for me. I'm 6'0", 183 lb. In most brands I'm a Medium, but in Castelli and Gore I'm a Large. The fit of the Large is perfect for me: snug without grabbing anywhere. It's so light that I don't even notice it once I'm on the bike.
This is my third pair of Castelli bibs. I took a chance on a size Large, even though with Castelli I sometimes need an XL. I'm 6' 180lb, and a bit longer in the torso than in the legs. The Agnels are a perfect fit, including the leg length. (I recently bought a pair of Castelli Neros, and find them shorter in the leg than I prefer.) The Large are a tight fit, but I like that. They're definitely designed for hot weather, with narrower bib straps and a lower cut waist. On the bike they're insanely comfortable, and the Kiss3 chamois is perfect for me, less bulky than some competing brands. These will be my go-to shorts through the summer.
I've been wearing wool for more than 30 years, and have watched it fall out of fashion, and lately, become quite trendy. Different weights give you different amounts of warmth, and the weave determines how well it vents when you get too warm and sweaty. Wool has 2 great properties: it keeps you warm even when damp (more warm than synthetics, anyway), and it resists smells. I've got different base layers and jerseys for different temperatures. For this jersey, there's not enough information to tell the exact temperature range, but if it's like other long-sleeve wool jerseys, it would probably work in the 40s with a base layer and a top wind layer, the 50s with either a base layer or a wind layer, and the 60s and low 70s on its own. The other important information that's left out of the description is whether its made of merino wool. Merino isn't itchy or scratchy.
I can't figure out why, but despite the bulk of these gloves, they don't keep my fingers warm once the temperature drops below freezing. At 28 deg. F., fingers on both hands get quite cold, even with heavy exertion. I've had to cover them up with nylon lobster wind covers to keep my fingers warm at 25 deg. F. Just not up to the job for me.
I've ridden my Atom tubeless tires for +1500 miles. The front tire is still pristine, but the rear tire was showing wear on the center of the tread after 1400 miles. Recently, at mile 90 of a century ride, an aggressive shift jumped the chain into the rear spokes, locking up the rear wheel, and putting me into a brief slide. The slide wore a patch of tire almost through the casing. After fixing the chain I kept going, and made it within 500 yards of the 102 mile finish before the rear tire blew. I can report that the ads are true -- you can ride a tubeless tire flat for short distances (gingerly) without damaging the rim.
I have problems with my toes going numb after a few hours in the saddle. The R310 felt amazing even before the custom heat molding. I rode in them for 100 miles before getting the molding done, and they're even better now.
The tightness of the straps is easy to adjust in the saddle. The extra wide main strap spreads the tension, and I've thrown myself at steep climbs without any perceivable stretching of the straps.
The mesh and sole vents provide lots of cooling, even through the worst of this summer's hot, humid days in Jersey.
I would never have chosen the bright silver color if there were other choices, but my wife likes the touch of bling.
I've been riding tubulars for more than 20 years. I recently upgraded my "classic" (i.e. old) road bike from first generation Dura Ace SIS to Dura Ace 7700 equipment. The final step in the upgrade was new wheels and tires: Dura Ace 7850s with Hutchinson Atom tubeless tires. I've always loved the feel and the low profile of tubulars, especially on cornering.
I got the Atom tubeless for the very similar profile to the Vittoria Corsa CXs I've used for a long time. The feel is, to me, pretty much identical. Feels the same cornering, descending, climbing. My riding and descending speeds haven't changed at all.
Mounting the Atom on the rim the first time was difficult. I found a video that showed the technique that worked perfectly on the second wheel with no tire levers. The trick is that you start the second bead opposite the valve and finish at the valve. Counter-intuitive, but it works.
I've put 400 miles on the new tires. So far, no problems and no visible wear. And the upgraded bike is a delight to ride.
The size information you've posted is for headgear. I'm wondering whether this is more of a race fit or a relaxed fit.
