Warning: Since the rim(s) or rims used have asymmetric specifications, it is important to pay attention to the location of the spoke holes when installing/assembling the wheelset. We recommend using the services of a competent wheelbuilder/mechanic who understands this. Mistakes in assembly can make the wheelset unstable and can endanger the safety of the rider.
