The Tub 26" is a new trike with 26" wheels all around. The steering geometry (caster camber) is the same as the Beach Raider and Storm. The track is slightly narrower at 28", 30" overall. The rims are 26", 36 spoke aero double wall. I used 20mm. hubs up front with stainless steel spokes. I have 1.50 slicks up front with 1.90 on the rear.
The frame is a twin rail design like one I made over 6 years ago. It is all round tubing with 1" x 1/16" wall lower and 3/4" x 1/116" wall for the seat frame. The mast is 1.50" x 1/16" wall and 1.25" x 1/16" wall. I used a section of plastic tube in the mast slide.
I had some concern about using 26" wheels due to the side loading. They haven't show any tendency to fold under heavy cornering. The wheels do make for a better ride.
The top pictures are from Win Del Park. A 250 metre ashfalt track in Windham Centre about 30kms. south of Brantford, Ontario, Canada.
