Legend to "Other Features"
Rnd = rounded crown
Flat = flat crown
Angl = angled crown
Vee = vee brake bosses
Mag = dedicated Magura mount
Disc = disc tabs
Pow = powder coated
Chrome = chrome plated
Water = water bottle mount
Frame weight includes bearing holders and bolts, but does not include seat post clamp.

Width to outside of frame is measured at base of crown. This is basically how much the frame sticks out toward your legs. 

Width between stanchions is measured at tread height 

Stanchion means fork leg.

Lateral tire clearance assumes Gazzaloddi 24x3/26x3 actual width of 2.75 inches 

Theoretical amount of flex is modeled as two parallel cantilever beams, and assumes 200 lbs being applied to leading pedal during climb. Pedal is assumed to be 6 inches offset to side of unicycle. Crown is assumed rigid.
