Wheel Spokes For each wheel build, different spoke lengths are required. This is to match the many different sizes of rim and hub, as well as the varying hole numbers and combinations that rims and hubs are manufactured in. Correct Spoke Lengths We stock a whole collection of spokes from Sapim, mainly in their race range which our wheel builders have found to be the best and toughest to build with. It is vital that the hubs and rim are built with the correct length of spokes, so if you are in any doubt contact us and let our expert mechanics advise you on the correct length. Alternatively you can select the rim and hub that you require and then let our mechanics do the complicated part and work out the correct length as well as building it for you.
