OK, I've been riding for 15 years on hardtails and bunny hopping was never an issue. I've always been able to clear obstacles up to a 12 inches high. This year I switched to a full suspension rig and I can't for the life of me clear obstacles half as high. There must be a different technique to bunny hoping a full sus rig! Seems to me that the suspension is absorbing the energy intended for the hop.
