General Info
Been wanting to build my own frame for a long time. This was done over the month of March, after business hours in my work shop. I did a very basic jig build concurrently with this as well. Most of the geo is based off of a Santa Cruz long Jackal, but modified for a 120mm fork. I cleaned out my scrap bin to do the assembly, and this being my first frame, I was not going to bother with new parts. 4130 steel, Paragon sliding drops. 69° head angle, 418mm reach, 560mm stack. Chainstay length about 400mm. BikeCAD for the design work. Frame weight came in at 1860 grams.
