oldbloke's mutterings

You're a bit stuck without a socket set for this unicycle, coz of attaching the cranks. I had one though.
It doesn't look as cheap as it was. The only weak point might be the clamps holding the ballraces onto the forks. If that goes, I'll find a workshop that can machine up some solid blocks to replace the pressed steel (unless it's aluminium).
Tell you what, though - you need an inside leg of at least 31", I reckon, unless you want to take a hacksaw to the seatpost.
In theory I can't get on it for a while - Excel's last estimate was May 20th, and the estimate has been slowly creeping later into the year. It can probably take a little bit over its nominal maximum load though...
