custom polo frame

got finished with this frame recently.
Jason was looking for a frame with as short of a wheelbase as possible and the ability to use large diameter 26" slick tires with disc brakes.
we decided to go with paragon slider disc dropouts in the rear because he is running a single speed setup. the disc mounts are attached to the sliding dropout so that once they are adjusted, they do not need to be messed with if you need to adjust the chain tension. the other nice thing is that they drop out vertically, so once you have your tension set, removing the wheel becomes very easy.
the tubing for the frame is straight gage most of the way around. the frame is a bit heavier due to this but it also creates a very strong frame.
i pondered putting gussets at the top head tube area, but the head tube is so short already, i felt it would do more harm than good.
the fork uses a pacenti moutain crown that looks a lot like the original Ritchey fork crowns.
i used a willits disc mount on the fork to increase the stiffness of the blade. it works to distribute the braking load along a large area of the fork blade to reduce twisting.
as far as the geometry. the seat tube is quite steep at 76 degrees and the head tube is also moderately steep at 74 degrees. Jason wanted the fork rake to be the same as the Fleet Velo Joust, but this frame is designed for smaller diameter 26" tires. so i decided to make the fork rake 37mm in order to get a similar Trail.
