Why We Like The ASSOS Mille GTO C2 Long Bib Short

Assos' pinnacle piece, the Mille GT Bib Short GTO C2, is made with precision and innovation to offer the comfort and support we need for distance rides and races. Yes, we like the tapered, wrinkle-free leg panels that off improved muscle support, but we also appreciate their length, which gives us the coverage we want on our ride. And, a reshaped insert eliminates friction and relieves pressure on soft tissue areas so we can pedal on without distraction. Assos paid attention to the finer details when designing the Mille GT GTO C2 to offer everything we'd expect and more from a bib short for distance riding.

Perfect bibs--no more misery

I've put it through the wringer
Size Bought:

This is my third pair of Mille GTO C2 Longs. Prior to these bibs, almost every ride over 30 miles resulted in abrasion wounds in crotch area. This is despite trying several different high priced bibs, gobs of chamois creme, and a few different saddles. I know I have sensitive skin, but was depressing. Then I read an article about a rider who tried these bibs. He described a situation similar to mine and said these bibs took care of the problem. I tried them and I am a happy camper. I have never had an abrasion sore since, even on my century rides which I do every month. Not even the hottest days have been an issue. It probably has to do with the floating chamois changing the friction dynamics, but whatever it is I am happy to pay the extra $$ for them. I still use chamois creme, but these bibs have been a game changer for me. As a bonus, I am tall so the long version allows me to look a bit less goofy in bibs. 6'4", 182lbs.

Best bib shorts I've ever worn

I've used it several times

I have owned many brands of bib shorts over the years and Giordana FR-C Pro was my favorite for the last 3 years. The legs and straps were starting to lose elasticity so I splurged and bought the Assos Mille GTO C2 Long. I am 6'1"/138 lbs. and size L fits like a glove. I definitely appreciate the slightly longer legs. The chamois is hands down the most comfortable I've ever ridden with... perfect for long days on the bike. This is the most expensive piece of kit I've ever purchased but my undercarriage certainly appreciates it!

Prefect bib

I've put it through the wringer
Size Bought:
6' 4"

I’ve worn this just about every day for a couple of months. My rides are rarely more than 20 to 30 miles, but in the past I have started to notice and be bothered by other bibs in the past. These I completely forget I’m wearing. I’ve ridden with them in temperatures ranging from about 40 to 85 degF. If riding in cooler weather, I may put something on my knees, but I don’t think I’d feel the need to have a warmer bib unless it became severely cold and windy or wet. I know these are expensive and hesitated at first, but I have no regrets whatsoever. They probably saved me buying two or three other pairs I wouldn’t have liked as much.

Performance and comfort at a price.

I've put it through the wringer

Wearing these is like riding around with the best Swiss masseuses, all applying the right amount of compression to keep you riding longer. Top sheet of the chamois inspired enough confidence to ride sans butter. The flammeD?Or version look pretty rad to boot. Assos? size-finding tool was spot on for me. I?m 6-foot, 190-pounds and Large fits perfectly. As these were a late-season buy for me, I can only assume they?d do well in summer heat. Judging by the thin dusting of salt from sweat evaporated on their surface even in October, I?d say they perform well to get sweat away from your skin and out in the air. My only gripe is the thick, pillowy feeling of the chamois. It works exceptionally well; and externally, it doesn?t appear to be the thickness that it feels. I?ve grown accustomed to the thinner chamois of others.

Cento replacement!

Just what you would expect to get from Assos& Premium and attention to detail. These bib shorts are fantastic. I couldn't ask for more from a bib short that replaced the Cento.
