I have a question about the front suspension on mountain and hybrid bikes. Let me give you a little background first,so maybe my question will make sense ! When I bought my first mountain bike in 2006 , I allowed the owner of the bike shop to assist me in getting the right size frame. That Mongoose was a pretty decent bike but after a couple thousand miles Kelly expressed an interest in riding ,so I gave it to her. Then I bought a Trek,but by this time I was a self-proclaimed "expert" and I determined the frame size all by myself (yes, I guessed). I have about 4600 miles on the Trek now (bought 8-9-09) and the front suspension is pretty harsh and stiff. I don't think the fork has deteriorated,I just think it has always been very stiff. When I go back to the Mongoose,I notice the ride is PLUSH compared to the Trek. Now my question : Do they put stiffer fork springs in larger frame sizes assuming that the larger rider weighs more ? How can I tell if this is the case ? Thanks for reading this inprobably long and boring post. Have a nice day !
