Stearing linkages

I've ridden a Vanguard for 11 or 12 years and it's bullet proof. Don't worry about it just ride it.
I have no knowledge of the Burley.

In the event of a low speed accident where the wheel gets forced to the right it will cause the
steering rod to get jammed against the head tube, this can cause the rod end bearing to bend at the
threaded part of it where it threads into the steering rod. The result can be a crack that's not
obvious and can cause it to break in use. We had this happen on two bikes that I know of. One was a
case of the owner letting a friend ride the bike who had a minor accident and didn't tell the owner.
We also had a case where the bike shop that assembled the bike adjusted the steering by backing the
rod end bearing out so far that there was only 1 or 2 threads holding it in place, it tore out of
the steering rod the first time the customer rode the bike. I had designed a fix for this problem
but never got around to implementing it before I sold the company. The rod end bearings should last
for a long time, we have bikes out there with 100,000 miles on them.

company (after) you sold your company? I have bent a few rods in my day and I do worry sometimes
about a loss of steering. Perhaps (IF) other companies have not yet addressed this problem, you
could sell your "Fix" idea?

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
end bearings.

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.

Under what circumstances did the linkage break and where did the break occur? this appears to very
serious if it happened while you were riding! If it was my bike I'd get in touh with Burley.

Mike Automobiles, airplanes, boats all have some sort of linkage that make the steering work, so
that a bicycle has a linkage doesn't necessarily mean it is a soft spot in the design. Ryan's have
been running well for years so no need to worry there. Burley needs, and probably wants, to know
about this right away. Be sure to give all the facts as to what happened. Your actions may save
someone's life. Speedy

It's a spot in the design, but I don't think it is any softer than any other spot.

I rode a cable-linked Infinity for about 8 years.

Due to my own negligence during maintenance, one cable once came loose. I just applied the rear
brakes, stopped easily and then securely installed the retaining clip I had previously overlooked.

Not a big deal, but it could have been nasty on a hill or in heavy traffic. But I could have also
overlooked many other parts on the bike and endangered myself.

I strongly suspect that steering linkages are more troublefree than many other components on
recumbents.

Another problem that should be mentioned! On a few older bikes we had a problem with the stainless
steel standoff that the aluminum steering assembly pivots on seizing up. This caused the assembly to
then rotate around the bolt and in at least one case caused the bolt to fail. If anyone should
experience the steering showing signs of binding you should dissasemble it and take out the pivot,
find some one with a lathe and relieve the center of the standoff, leave about 1/2" of contact area
on either end. Make sure the inside of the aluminum part is clean (scotchbrite works as good as
anything) and grease.

They did a really nice job on it!
