Hand-built in Southern California, Box Three™ Wheels are made with Box One™ front rims and 36-hole, Box Three 10mm Rear Hub laced 3-cross front with 14-gauge stainless steel spokes and brass nipples. Our Box Three Pro Rear hub has a super-fast 120 Tooth Engagement system, precision sealed bearings, and a steel 10mm axle. This creates a great hub with fast engagement at a wallet-friendly price! Box One™ Alloy Hoops have a no-nonsense low-profile design that eliminates excess material, making them some of the lightest weight double-wall rims available. Featuring single eyelets to help prevent spoke pull-through, higher spoke tensions are possible. Box One™ Pro Spokes feature a double-butted 14 gauge spoke (2.0/1.8/2.0mm). Our Pro Spoke Kit is lighter AND stronger than traditional straight 14 gauge spokes. This is possible by using a spoke that is 14g at the ends but 15g in the middle; this combination makes for an exceptional strength to weight ratio. Additionally included are Lightweight Black Anodized Aluminum Nipples to reduce rotational weight further.
