Got off work tonight, road home and relaxed for awhile. Decided to take a ride and wound up riding for almost 2 1/2 hours on my new single speed MTB. I didn't know that one gear could be so fun, after getting my chain problem fixed. My legs are burning, my lungs are screaming for air, man I feel good. My new saying "get one and be done". Oh, this is my first bike I have had since around 1997. One question, are there hills that I might just never be able to climb, or are they all doable ? Thanks for this S/S forum, you guys gave me the inspiration to try something different, I will never go back.
