if thats true.... I got A LOT AND I MEAN A LOT of donutes coming out of my body.
I thought I wouldnt hurt as much as I do since I do ride (road bike) all the time and can do a lot of miles on it a week (just riding on road bike I average 350 miles/ a month in summer... 250 in winter so far). Guess I was wrong!
Do you think using a mtn bike uses different parts of the legs versus road bike?
