Spoke Calculator

Instructions:

• • Check out the new Berd Spoke Calculator for Android.
• • Berd spoke lengths are different than metal spoke lengths. The methods for measuring ERD in the table below must be used to calculate correct spoke lengths.
• • Berd spokes are compatible with all J-bend hubs, all tangential straight pull hubs, and some radial straight pull hubs.
• • If unfamiliar with measuring hubs, using 2:1 lacing, or lacing non-standard components, contact Berd for more information.
