The Sunday Dark Wave frame is Broc Raiford's signature chassis and built for abuse. With Sunday's dent-resistant Wave downtube, integrated seat clamp, tapered stays, and integrated chain tensioners, it's super dialed. Broc's preferred 21" top tube, 75.2 degree HT angle, slammed 13.25” chainstay and tall 9.25” standover give this big boy the perfect balance of response and stability.

All this makes the Darkwave an affordable and versatile signature frame that's designed to handle Broc's 4 foot high bunnyhops, massive drops, and all the tech combos in between.

Wave Down Tube:
Down tube dents are common with the competitor's frames and they significantly weaken the front end of your bike. The double-butted, 1.45" diameter down-tube feature Sunday's proven Wave shaping to fight denting against contact made from a rail, ledge, coping and whatever else happens to get thrown at it.
Tapered Chain & Seat Stays:
Both chain and seat stays taper to provide a refined and clean look to the frame while still providing strength. They are both angled on the inside for improved chain clearance and weight savings.
Hollow Dropouts With Chain Tensioners:
Hollow 8mm wide dropouts are as light as a solid 5mm dropout, but over twice as strong. There is a small internal chain tensioner to hold the wheel in position and to simplify wheel removal.
