If you run the tyre at low pressure check that the brake caliper doesn't
rub against the tyre. This is particularly a problem if the caliper is
in the original low position. Even when it is visually clear,
compression on landing and tight turns whilst taxying can cause the
caliper to rub against the sidewall. Look for a circular mark on the
sidewall during walkrounds. Rotating the caliper rearwards to be at
least the in line with the trailing arm is a good idea.

Frank,
Congratulations on your starting on grass. Smart move.
I'll research the block with the company. Do you have the dual shock
absorbers installed? Refer to the new manual Chapter 29M
What is your main tire pressure? Many prefer to run a low tire pressure
to preclude bounce. If you've got it firm, you're landing on a beach
ball. Sounds like you've got the pressure up.
We inflated the only mono I have been in at 18 pounds on a 7 inch tire
and found it more comfortable with the pressure at 14-15 psi. The owner
prefers it at this pressure. The plane squats in on landing.
Love to hear other comments from you experience mono pilots on tire
pressure and concrete runways to get a feel for what works for each of
you.

Subject: Europa-List: Bouncing Mono Classic
Dear all,
I am slowly gaining experience with my monowheel, but today I did a few
patterns on a concrete runway (before I mainly used grass strips as a
beginning) and experienced hefty "bouncings" on landing, causing me to
go around twice-although touchdown was quite smooth it threw me back up
in the air like a rubber ball (I tried touchdown speeds between 45 and
60 kts with steep and shallow approaches, with and without flaring). The
mono is one of the first from 1996-1998 with the red rubberblock as a
shock absorber- since the a/c has now around 600 hrs/700 landings, could
it be the case that it needs to be replaced? Or could it be something
else? I know that the mono tends to bounce if not landed "on the point",
but I never experienced it in my past 25 landings so badly. Did anyone
have a similar experience? I use the large 8.00 tire on it.
Thank you for your help
