I have a pair of Canari Shorts. Its my first cycling shorts. I've worn them maybe 7 times for 1.5 hours at a time as I'm a newbie. I've already noticed I've developed wear marks (like chaffing) on the shorts between the legs. There's no shaffing of my skin, I'm very comfortable riding on my Specialized Milano saddle on my Specialized Sirrus. I'm wondering if the saddle is too wide & causing excessive wear or am I positioned wrong or a common problem with these brand of shorts. It looks like only a few more rides and i'll need another pair of shorts. Oh yeah, I've got big thighs too. Can anyone please advise me, thanks?
