Everyone who owns a Semcycle, please raise your hand.
Everyone who does NOT need to carry along a toolkit with you anytime
you ride more than a mile, put your hand down.
How many of you still have your hands up?
I'm more than a little frustrated over two mechanical problems I have
been having with my recently aquired 20" Semcycle. After having been
away from the sport for several years following the theft of my
Schwinn back around 1989 (who the hell steals a unicycle?!), I bought
the Semcycle in August from the Juggling Capitol in Washington, DC.
It was delightful to discover that I still knew how to ride, and
nostalgic to remind myself how much my crotch hates unicycle seats.
So what are the hardware problems I am having?
Number one is a slow leak. Over a two mile ride I can lose as much as
3 PSI in the tyre. It also loses air when I am not riding, but I do
not know at what rate. As much as 10psi over two days of not using it
has been observed. It basically means that I have to inflate the tyre
every single time I am going to use it, even for the return commute
home in the evening when I'd just ridden it in ten hours earlier.
The other problem, much more frustrating, is with the left crank. The
retainer nut loosens up, eventually enough so that the crank loosens
up on the axel and gets progressively worse, the point where it can
just be pulled off. I thought I had this problem***ed when I really
tightened down the nut so much that I was afraid of stripping the
threads. It was further down (ie, tighter) on the bolt than the right
crank. This worked fine for maybe a dozen miles, but just two nights
ago, in the middle of my commute, it went from rock solid to
completely off in less than half a mile. This was especially annoying
as I couldn't even put it back on and tighten it up because not only
had the dust/retainer cap fallen off, but the nut had also come
completely off the axel and was lost.
This weekend I intend to get to hardware store and find a new nut, and
probably thread lock it as a prophylactic against this happening
again. But still, even with such a solution at hand, it bothers me
that I have been having these problems. What are your opinions?
