Ok, now that I'm in the market for another bike, I decided on what I want. I am looking for a STRONG but very light frame or even a complete bike. I want a singlespeed for sure and I'm hoping for the bike to be in the sub 20 pound range. I have looked at tons of frames and bikes but can't deicide on which one is the best. My budget is around $2500 but preferably less. I am 5'11" and about 195 fully clothed and I ride very aggressively and for rather long amounts of time(my usual run is a little over 25 miles). I ride mostly street but I like the option of being able to ride trails. I just need some suggestions on bikes and frames that would suite my needs. Any help will be greatly appreciated. -Will
