* ERD Calculate
ERD is short for effective rim diameter, it is the maximum distance that spokes bridge going from one end of the rim to another.
How do we calculate the ERD of our rims? Below are calculation equation and sketch for your reference:

650B MTB RIMS ERD calculate

ERD=Rim outer diameter-(rim depth)*2+(Rim nipple bed thickness)*2

For example：

ERD of AD730-XC rim=595mm-22mm*2+3.5mm*2=557mm
Most people prefer ERD including the length of the nipple head.
However, customers may use different nipples and components for building.
Please add the length of the nipple head (2.5mm~3mm generally) for your spoke calculation.
If the length of the nipple head is 3mm, then ERD of your AD730-XC rim is 557mm+3mm*2=563mm
A: Rim nipple bed thickness (=3mm)
B: Length of nipple head (2.5mm~3mm generally)

LightCarbon MTB rim has passed UCI 120J impact testing (double of UCI standard 60J !)

The falling mass weight is 17.5kg, and the testing height is 700mm (=overall height 1310mm-610mm initial height).

So the impact testing energy is 120J. (=17.5*9.8*0.7)
