Luxe Wheelworks Tech Journal no.24

"OCR" stands for Off Center Rim. Velocity produces an OCR version of its Aerohead clincher rim to help wheelbuiders manufacture a stronger rear wheel.
This OCR helps improve the rear wheel's bracing angle
.
Some wheelbuilders with more experience than I have do not like building with OCR style rims. I look forward to learning for myself why they might think that way. 

OCR rims are used on rear wheel builds only. Front, rim-brake wheels are symmetrical. 

White Industries labels only their rear for-Campagnolo hubs "H3". Their front road hub and rear-Shimano hubs remain labeled "H2" being their first production model with this hub shell design.

This wheelset is for a light rider so I designed it with a 24/28 spoke count and alloy nipples throughout. 
Velocity does a fantastic job machining their braking surface as you can see here. Velocity pin their rims together. This joining process can result in the rim having a flat spot. This requires some extra work on my part to bring the wheel to round along the Y axis.  
I feel like I am hitting my stride as a wheelbuilder. These came out great.
