Old Manitou SX are totally shot. The bike currently has a 1" threaded head-set (Deore XT) with an old 136mm long Mech-Tool Stem. Local Shop can source Mazocchi Pro Lo with 1" steerer tube and 100mm of travel, new A Headset, shims and shorter stem as I wish. Any suggested alternatives on the forks or suggested -ves to this plan of attach to getting a much loved hardtail back up to scratch?
