Hi Gavin,thanks for your reply.
i need two
the designs of interest;
the fixed back vios for passenger, and either
the recliner gias or stradia.
(both available in "sport" type.)
what's the difference between them, and between "sport" and normal?
weight is the key factor here
i will also require frames i guess, preferably fixed and lightweight
i'd like to sit higher, so perhaps the lower leg version, to give clearance under the steering wheel?
many thanks
gavin
