Chaffing?

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?

I also end up getting blurred patches on my shorts but that's usually my really old shorts.

It could be that the fabric isn't very high quality (high priced shorts do last longer as the fabric is better).

Another thing to look for is do you have a saddle bag on your bike? Does it attach with velcro? If so is there anyway the velcro is catching your shorts?

If the rubbing is on the outside of your shorts, then +1 on the saddlebag. That's a very common issue. It doesn't even really have to be catching on the velcro, just the edge of the webbing. A small piece of matching electrical tape on the strap will solve the problem.

Another possibility is the saddle clamp, if you have your saddle set very far back on the seatpost. To fix that you'd need a different seatpost with more setback (assuming the saddle is in the position you want it). Last possibility is the saddle itself, especially if it's a tensioned leather saddle. Check the outer lower edges for burrs that you can gently file off.

Thanks to all...it was the Velcro on my saddle bag...who would have "thunk"?! ;-)
