I ride a Longbikes' built and Ryan designed Vanguard with 25,000 miles in five years (this is the
beginning of my sixth year). I have had no problems with my steering linkage. I do attend to it as I
attend to all potential single failure catastrophes.
I noticed somebody's Vanguard with a kink evident in the end of the steering tube from an excursion
as described by Mr. Ryan.
A friend that rides a Ryan Vanguard complained once of losing the forward rod end nut/bolt. We
discussed pinning the bolt. I have and will continue to use a ny-lock nut and aircraft grade rod
I change the two bearings in the steering/handlebar mount assemble at each annual inspection. I
changed the 5/16" steering assy bolt from the common grade bolt to Grade-8 (marked not tested) in my
first year. This bolt takes bending stresses from the barend extensions and the original common
grade bolt failed under controlled conditions due to bending fatigue.
I recently upgraded to Longbikes' hornless & hip-jointed seat frame. I have an essentially new
seat-mesh and a used/repairable mesh for the horn-ed style seat frame available in the name of good
fellowship for the cost of shipping.
