From ages 15-18 I did a lot of road biking. I "retired" due to college and dabbled with a few xmart mountain bikes over the years. Back in February I did the last of many ankle sprains (they could hear the pop 100 yds away) while doing some wind sprints--it still swells up and gets black and blue if I try to run any more than 20 yards--guess at 31 I don't recover like I used to. Anyway, went to a nearby shop and bought and entry level KHS--which I've done some upgrading on--and got in to MTB riding. I also picked up a used Bridgestone RB-4 for commuting, rainy weather riding and to get that occasional distance fix in. I'm glad I'm back.
