I'm having trouble with my semcycle XL.'s seat post. The back of the
post has been dented in pretty well by the improper clamp design. The
dumb clamp is welded/brazed on at the top and really only applies
clamping pressure at the edges of the slit cut in the downtube.
I'm planning on cutting off the clamp with a little cutting
disk. Then I will either bend the downtube round again or cut the out
of round part off and make a new slit. I'm also working on getting a
proper sized clamp that applies the force more uniformly around the
If anyone has had this problem please drop me an email
describing your solution if any.
