First Bike Frame - This is the first frame I built. All design and fabrication occurred at the Lemelson Center of Hampshire College. Used BikeCAD Pro for frame dimensions and design. Built to my body measurements.

This frame was built to be a durable, highly maneuverable, singlespeed with capabilities for both urban and off-road terrain. The geometry is similar to a mountain bike. The sloping top tube:
1.) Allows for considerable stand over space and therefore increases rider mobility, which contributes to overall maneuverability.
2.) Reduces the dimensions of each triangle, resulting in a stiffer frame and less material.
3.) Shortens the wheelbase, decreasing the turning radius and bike profile.

The rear triangle was built for a 700c wheel and has enough space to fit a 2.5" tire. This provides the option of using a slim racing tire for urban environments or a thicker off-road tire for increased traction during mountain use.

Specifications:

- Columbus Steel tubing
(0.034" wall thickness)
- Double-butted seat tube (1.125")
- Top tube (1.125")
- Down tube (1.25")
- Head tube (1.125)
- Seat stays & Chain stays (0.75")
- 68mm BB
- Surly horizontal dropouts


Used Anvil BikeWorks frame fixture and seat stay mitering fixture. Bridgeport mill. Miller TIG welder. Frame was sandblasted and clear coated.

Chain Stay Drafting 'Tool' - This is a SolidWorks part file that models the geometry of the chain stays. The sketch dimensions provide information needed to calculate tube lengths, bend angles, and mitering locations. The model takes into consideration dropout placement and size. A sketch for tire placement and sizing was also incorporated so the triangle could be built to wheel specifications.
The builder can reuse the model with new initial geometry, effectively making it a tool for designing part of the rear triangle.
