so ive been reading tons of reviews and stuff, and i see a lot of singlespeed 29ers, most of which have regular front forks not shocks. so my question is, besides low maintenance, why would u get a single speed mtb with a stiff fork? i dont understand theres climbing and decending, so thats what gears are for, and rocks and bumps and stuff which is what shocks are for! also they are usually more expensive, when they come with less parts! can someone please alleviate my confusion.
