Building a wheel for a friend ( echo rim (26") onto t-rpo hub...does anyone know the spoke sizes for it, or just the diameter of a t-pro hub ...... Going to be using this spoke calculator: http://www.wheelpro.co.uk/spokecalc/ i know the erd of the echo rim (543mm), and i know i dont want it dished to either side ( so both sides will be uniform length spokes, therefore making the build easier ) Can anybody help?
