I have a Specialized Rockhopper that I bought new about 4 years ago to get back into cycling after many years (since childhood). I enjoyed going on trails now and then but eventually lost interest (or got busy with life or both) until last spring when I started riding a lot on the road. After a few 20 mile rides I decided that I needed to switch the tires to slicks so I replaced the knobbies with Kenda slicks 26x1.95 . Also, I installed barends to help eliviate the numbness on my hands. I have since enjoyed very much riding from a few miles around the neighborhood on paved roads up to 45 miles that I once did.
I am interested in doing some charity rides this spring/summer. There are two in particular that my company participates in for donations etc. I have noticed that for the longer rides like the MS150 (two day road riding event, 75 miles each day) most folks use road bikes.
What do folks that have done longer rides on mtb think? Is it unecessarily hard, or even prohibitive? I am in fair shape for my age (45 yo) and I am planning on training before such a ride. Also, do you think I would be better off with getting narrower slick tires,like 26x1.3?
I wouldn't mind buying a road bike but at this point I am concerned that after a couple of months it will be collecting dust (maybe even both bikes). If after this summer I still feel as I do now about cycling I will buy a road bike then.
