How To Use The Dt Swiss Spoke Calculator?

[Carlperkins]

ok so i have an echo sl rear 24" 32h rim. (Weight : 565g. High : 23mm. Width : 38mm.) - info from the internet.

and im going to buy an echo tr non disc rear hub. http://www.tartybikes.co.uk/135mm_fixed_hubs/echo_tr_rear/c21p10708.html (Flange Diameters: 40mm

- Centre to Flanges: 35mm)

can someone please tell me how to use the spoke calculator? i'm having difficulties

much appreciated. carl.

ok so i was trying to measure the rim diameter and i wasnt sure whether to measure from the outer edge of the rim to the other edge (the rims absolute widest point)

or whether to measure from spoke hole to spoke hole. anyway i measured spoke hole to spoke hole and it came to 475mm (edge to edge is 521mm)

spoke hole to spoke hole example..

then i punched it all into dt swiss and this is what came out...

anyone think this is right?

According to this the ERD of the rears is 480mm, so you weren't far out

EDIT: Any reason for 4cross? Wouldn't bother with more than 3 to be honest, just a little simpler.
