Thick Stemless Rebars

A PA flatlander named Jeff came to me with a drawing (at bottom) showing his design for a handle bar that clamps directly to the steerer tube and eliminates the need for a stem. The only design change I made was to use a curved cross bar with the same type of reinforcing gussets that are used in the Thick Rebars. I felt that this would make the bar stronger and stiffer. Like the Rebar design this custom one-off has plenty of knee clearance and grip/lever room.
Six and a half Inch rise
These bars are so good I gave them a halo - really well behaved.

You don't have to be an artist to know what you want. This simple sketch started it all.
