ok, so i literally have 10 pairs of assos bibs in my drawer. pretty sure my wife has no idea how much these things cost, because if she did, there might be a discussion. in any event, the cento was the first of the s7 line i purchased. at first, i liked it. it felt good; the penthouse was comfortable, etc. at that point, i was riding for a couple hours. then i started training for longer rides/races. i was riding for 5 hours plus. about the same time, i bought a couple pair of the campionissimo bibs. i continued to rotate the new bibs (most of my assos is the s5 line), and when i got to the cento for a long ride, i was always irritated down there. this never happened with the old s5 bibs unless i was wearing my old xlg sized bibs. for better or worse, all this long distance caused me to lose some pounds. anyway, i put the old xlgs aside but always preferred the s7 line, which was all straight xl. but they don't fit that way. the centos fit like a larger size. there's too much fabric between the legs; it bunches up and causes irritation. it's a problem and a bummer . . .
also, someone asked if there is a bib replacement program. i crashed in a pair of s5 bibs last year. tore up the bibs pretty good. i sent them to assos and they sent me a new pair. now that's customer service. that's why i love assos, but i can't say i love the cento bibs.
