Here is the finished product (650B with Paragon stainless sliding dropouts). The finished filing without a vise was a bear, but everything cleaned up really nice. The paint was done by Class Act Powder here in Portland. As for the ride, it is very responsive and loves to climb hills, basically everything I could ask for. The total weight is 26 lbs. 4 oz. with suspension fork and pedals. I definitely learned a ton about both design and technique, which I will take forward with my next build. A big thanks to Ron and Gary.
