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. | |
 These bars are so good I gave them a halo - really well behaved. |

From this angle the steerer clamp is visible. Note that these bars have no rearward sweep but do have some upwards sweep. |

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