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. Each wheelset is built with Wheelsmith Spoke Prep and inspected using a DT Swiss tension meter for quality control. Includes both front and rear wheels.
