I've done quite a few centuries (4 this summer alone), and I'm riding on a Ruby 155...which is a tad bit firmer than the Jett. Today I did an 88 mile ride, which is the longest I've done in about a month...I was experiencing that "bruised" feeling at about 70 miles today. Sometimes I can go the full 100 miles without any problems, and sometimes I can't. So (for me), I think it comes down to the shorts I'm wearing. Today, I was wearing a fairly old pair of Pearl Izumi, so it could have been that the padding was just worn down or bunching up on me. I might shoot for 100 miles tomorrow, so I will wear a different pair of shorts and see if I get that soreness again.
