My new Chicago winter ride! and that means ready for ANYTHING the sky,lake and planitary orbit/axial tilt can muster.
The first drawing is of the overall design. You will notice a Paragon machine works sliding drop at the rear of the SS/CS's. this was an excersize in machining but really not useable. Reason is that there is no reason to use unless I plan to run rear disk brakes... and for this one.. no. Gonna be fixed with a really low gear ratio.. something like 32/18 front/rear cog. The second image is the fillet braze forward drop I designed for the task.
The slider design+ crown weighs in at 15 oz.. almost a pound. I also plan to use a SON28 disk brake friendly dyno hub= 1.5 lbs. all by itself.
Sooo, thats 2.5lbs of frame weight before I even grab a tube for the front triangle. The front tri will be of .028" wall strait gauge Cro Mo hand bent by my buddy Steve. The rear triangle is of deda 's' bend cs's and telescopic .625"/.5" strait gauge tube in wishbone shape.
About incorperating the SON28 hub.. the fork blades nest in a custom crown cut by yours truly.. see previous posts....
25.4mm x .9/1.3mm round blades. strait to hub. running a front and rear light powered off the dyno. Both have capacitor powered stand light power.
