i have watched several videos of people riding front suspension bikes (1) very fast (15-18 mph easy) on flat trails (2) climb at a decent speed on big hills.
front suspension is tuned so there isn't much bobbing as they climb hills or sprint on flat ground. its very efficient and moves only when riders hit something. even when riders brake hard, there isn't much fork dive. this is nothing like how i hear in the forums. people say front suspension robs energy or that "it isn't fun to be bobbing up and down when climbing".
question: if hardtail with front suspension very efficient on a mountain, why can't it be just as efficient on the road? let's assume you change the tire to slicks like schwalbe big apples. to be clear, i'm comparing a hardtail mtb with only front suspension to another mtb or hybrid with a rigid fork. NOT comparing mtb to a road bike.
is it because the ht is efficient on road but a rigid is even more or is this another case of theoretical not translating to reality? i don't mind $65 / year maintenance and a little loss of efficiency for the freedom to take my only one bike (pre-ordered trek cobia 2011) wherever i please.
