    Hi, I am building a front wheel with a dura ace hub and a 20mm v shaped 32 hole matrix clincher rim.
    Want to build 3 cross. Could you please tell me the spoke length that I need? Thanx

    You will need to determine exactly which Matrix rim you are using by specific information on the lable or following the instructions included for measuring the RIM ERD (Effective Rim Diameter).
    Please be aware that different spoke calculators define ERD in their own way. Difference in methods can result in 6 mm differences in the ERD presented in the table.
    Sometimes data posted in tables isn't the same as what the "built-in" calculator expects.
    It is best to learn how to accurately measure ERD for yourself and know how the formula uses the data.
    Rinard's information on how to measure both the rim and hubs is on his site at URL:
    You will need to scroll down to see the information or click the link at the top to pop you down to that area.
