Hi, I just ordered a pro 2 and rhyno lite (24") rim from work, it should be here on tuesday-ish now I can build a wheel but of course first I will need to know the spoke length I need to do this I was going to use the DT swiss spoke calculator. Thing is Iv encountered a few problems... Basically I have no idea of the measurments that I need, the rim is already on there although there is a measurment it hasnt given.. My question is could some kind knowledgable person tell me what it all stands for, also does anyone know the measurments I will need for a pro 2 trials? Its quite a long shot but I would like to order spokes on monday for it (again probably through work, trade price for the win) that way I can have it built by mid-week and hopefully ride by about thursday-ish. cheers, O and heres the calculator...
