Normal suspension forks (e.g. Spinner Grind and Meks/Saso) often interfere with the chain lines on short wheelbase recumbents. I've been looking into the feasibility of adding a suspension fork to my Metathesis. Recumbentparts.com have some "headshock" style forks but they seem to have tight clearances. Have come across airwings-systems.de Revolution fork, http://www.airwings-systems.de/revolution.html and am making enquiries as to availability and price. Might be a good option for Fuego owners too.
