The Darkwave is not only 100% built out of 4130 chromoly, but it also features Sunday's signature dent-resistant wave down tube to give riders a little extra peace of mind when things don't go according to plan. It stays looking clean with refined details like an integrated seat clamp, tapered stays, and integrated chain tensioners. Removable brake hardware and gyro tabs are also available when you need them and disappear when you don't.

Broc’s preference in geometry gave the Darkwave a 75.25° head tube angle for keeping the front end responsive, and a slammed 13.25” chainstay combined with a 9.25” standover to give it the proper balance of pop 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 can significantly weaken the front end of your bike. The Wavelength's double-butted, 1.45" diameter down-tube features Sunday's proven Wave shaping to help fight against denting from rails, ledges, coping and whatever else happens to get thrown at it.
Miter Cut Top Tube:
A miter-cut top tube creates a precise joint with the seat stays during welding. This increases the strength substantially over frames that use a “sandwiched” top tube at this critical junction
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.
