Sunday Darkwave Frame
Sunday Darkwave Frame
Broc Raiford's signatue Darkwave frame from Sunday.
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.
