I started commuting (30km/day) in February and during the year I switched from a rigid bike to a MTB with suspension. Considering the state of the roads I take (and off road bits) and the distance, the MTB (poor suspension and all) is far more comfortable than my old bike. I may not be the fastest but I no longer feel pain in my hands and wrists, like with my old bike.

So yay for front suspension bikes!
