Thanks for looking. I realize there are as many threads on this topic as there are opinions, however, I did not think it would hurt to add another. I recently started riding my Ironhorse Sage hybrid again due to a foot injury that has curtailed my walking. I am 54, overweight but I like to think I was and still maybe somewhat athletic. I've dropped 60 lbs since May, halfway to my goal of 180. Anyway, The ironhorse works but I do not like the grip shifters and from talking to folks at work, a change in technology may be in order.
So basically my thoughts are to either invest in different shifters or buy a new bike. I ride on mostly pavement and hard packed dirt trails. I am leaning toward a mtb (Trek 4300d or Fisher Wahoo) and intend on putting slicks or combo tires on it initially. I have also been checking out the 29ers but have not actually put any saddle time on one. Any thoughts would be appreciated.
