I just wanted to send you a quick note of 'Thanks!' for the incredibly helpful website and articles you have published on wheel building. I am currently building my first set of wheels (26" street trials bike) and I have to admit that I have been struggling with the concepts of 'correct' spoke tension. Your article published on June 21, 2019 is the BEST thing I've ever read or watched (youtube) on the subject - EVER! My new found understanding plus your excellent calculator is exactly what I needed to finish this project correctly.

Thank you so much for providing this wonderful spokecalc.io site! I am in the middle of building my first set of wheels. Found some great content on Youtube and Sheldon Browns' pages already, but especially the sections/calculations for the tension ratio on your site helped me understanding a lot and answered some open questions! Great calc and nicely written articles to learn on wheel building details! Thanks again
