"I am builing a wheelset for an on-topic bicycle and am unsure of how to calculate spoke length. I tried the DT calculator online, but the rim I have selected is not an option there. Perhaps a list member has built a similar wheelset and can direct me to the proper length? Campagnolo low flange record hubs, 32 hole, 3-cross laced to 700c Torelli Master clincher rims. Any thoughts, gang?

hi Matthew,
I've got an old copy of Spocalc that says that the Torelli Master has an ERD of 606mm. SpoCalc says that the number came from Sutherlands. With the dimensions from your hubs, you should be able to run the numbers and get the correct spoke length.
For instance, the basic Record front hub will need 297mm spokes, per SpoCalc. The length of the rear spokes depends on whether the rear hub is set up for 120mm or 126mm OLD.
