The BA30 is our most burly rim. With internal bracing and reinforced bead-wall, choose the BA if you're particularly hard on rims. Some people like to run a BA30 on the back and a Phase30 on the front.
If you're lacing your own wheels, all of the build specs are available on each page under the product images.
We've taken great care to design the R4 hub to be fully serviceable and all replacement parts and bearings are available to purchase.
