no experience with the purefix wheel set but my bike came with a pair of deep v rims stock. personally not a fan of the aesthetics and they were heavy, swapped them out for other wheels i had and sold those boat anchors asap. i'm sure they're ok for puttin around as long as your not riding gravel and jumping curbs, but i don't think the design would afford you any more in durability then a lighter wheel set.

*edit: buying the purefix wheels with the intent on swapping hubs down the road is a terrible idea. i doubt the rims and spokes are worth the effort to relace to new hubs.
