I need a new seat bag for my road bike...picked up a few different ones and had to take them back...the problem is with leg rub. I had one I got in Belgie, a no name thing with no velcro or post strap that worked great...just a bag you could tie up tight. But after duct taping it together for the last 4 years it finally **** the bed. So I need a medium sized bag with no thigh rub. Anyone else out there gone thru this and found a good bag? thanks...
