You will find listings for ALL wheels, numbers next to technical illustrations will match with part numbers and listings on the right hand side. On the far right-hand side you will see what bike applications suit each part number, in short parts listings that match bike.
The parts list also gives spoke lengths and nipples to match. For example; some wheel applications both take 238mm and 243mm length spokes, (using front 17" wheels as an examle here!), but some use M3.5 nipples and some use M4 niples. So pick the correct part number for your bike application and you will have exact length and nipple size. The angle the nipple locates the spoke is dictated by the nipple holes pressed into your rim, correct spoke length means the nipples will locate correctly!
