I bought this 29er single speed rigid bike awhile back because the LBS talked me into it as my first MTB. I do not like the aggressive geometry since I feel like I am hunched over all the time. Its a great bike for what its built for but I would like something of a more relaxed geometry that I can ride for 3 to 4 hours. I have been thinking of putting on a nice suspension fork but I am not sure if that will do the trick. People keep telling me to buy a full suspension rig with all the gears instead of upgrading this bike. I test rode a Felt Redemption and immediately fell in love. I then went to another LBS and they tried to sell my a Gary Fisher HIFI Plus which felt great also. Other bikes I tried were a GIANT TRANCE X 2. My riding will mostly be light trails long distance but I like aggressive riding sometimes. My main concern is comfortable geometry. Ive even thought of buying a Diamond Back 29er for the price. I am 6' 175 lbs 38 years old. Any suggestions?
