Sunday Darkwave Authentic BMX Bike Description:

The Darkwave Authentic BMX Bike is the authentic signature model of the incredible Broc Raiford and the bike is built up so high-end that it's virtually the same bike Broc actually rides. This beast of a bike features Broc Raifords signature aftermarket Sunday Darkwave frame, which is 100% 4130 chromoly and features Sunday's signature wave downtube, which not only looks cool, but is dent-resistant.  Everything else on this bike is aftermarket as well, including the Sunday Darkwave fork, Odyssey Thunderbolt Cranks, Odyssey Broc Bars, Odyssey Clutch V2 Freecoaster, and the list just goes on. As an added bonus, Sunday offers a lifetime warranty on their 41-thermal components on this bike, including the fork, cranks, and handlebars. This is a pro bike at a fraction of the cost!

The bike comes in this 21.25" toptube option that is left hand drive and is also available in a 21" toptube option that is right hand drive.

Super awesome bike! If you parted out this bike it would actually be over $2k. Solid deal for a basically custom complete. Someone at my skatepark actually asked if I built it custom. Just make sure you know the 21.25 TT is left hand drive! I’m left foot forward, so really I should’ve order the 21 TT right hand drive. But I don’t grind much anyways so I kept it.
