So, with Covid related spare time and boredom I've thought about Welding a Frame up. Has to have been about 20 years since I've TIG welded, but given I'm currently out of work for the forseeable future (Massage Therapist) it seems like a good time have a crack at doing something I've wanted to do forever (my Trade School Teacher used to fabricate Road Bikes and it looked pretty cool). I'm thinking a 29er Hardtail (130mm fork) for simplicty, and its something different than my Trail 27.5 Duallie. Looking for something to ride up and down Red Hills trails like Fall Line and Pins and Needles (I'm a conservative rider, keep the wheels pretty much on the ground, don't take on the bigger tracks down Eatons.) This is my first crack at the Geometry and would appreciate any feedback and opinions if anything looks like its out. I'm 170cm tall, and generally fit either a Small or Medium Frame, but I've only had a handful of bikes and don't really know what feels best re. Reach, Stack and Top Tube numbers.
