The DM’s are generally not light (unless you look at the new off road one that
has the new hub). It is incredibly rigid which gives better response to control
movements. It is machine that will out last any other. Remember this is not a
bike and lightness is not everything, rigidity also affects controllability.

Simple, the Sem is a beautiful unicycle, but it is not as durable as the DM by
half and anyway cannot be used for muni effectively as there is not enough
clearance in the frame to fit a sensible tyre.
Here is my comparison by components. DM very rigid/bombproof being made from
CrMo, Sem not DM has machined bearing holders (essential for bearing life, with
abuse), Sem used std. pressed steel ones. DM has flat topped frame for foot
control, Sem hasn’t. Sem’s have a narrow crown (good for not catching knees, but
not good for foot control) DM has bombproof hub, Sem does not - expect a new hub
every year at least if you do any serious riding. DM has a 40 spoke wheel, Sem
has a 36. DM had BMX style hollow cranks (Superb), Sem has standard uni ones.
Basically these 2 unicycles should not be compared together, they are made for
different jobs. If you want to do Muni, get a Muni.

I only sell the frame. If you build it with the same hub as Dave’s DM you will
look at over $1200. I don’t know if you consider it a good recommendation since
I build the CF uni but I believe that the new DM muni is a really good machine
and is definitely value for money. It will last and perform.
