Sunday Darkwave Frame Review

Sunday's Darkwave frame is pro rider Broc Raiford's signature frame. Designed with the dent-resistant downtube, strong gussets, and more. This frame is a strong and stable machine for hefty street riding. Available in 2 colors and 3 toptube sizes. This frame weighs around 5lbs, but a specific weight is not released.


Frame Features
100% 4130 chromoly frame
Broc Raiford signature geometry.
Removable U-brake hardware and Gyro tabs
Integrated seat clamp
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.
Butted Seat Tube & Miter Cut Top Tube:
The seat tube is where all three triangles of the frame meet and it is crucial to keep this junction strong.
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.


New for 2020 is Broc Raiford's signature Darkwave in Matte Dusk Fade and Matte Raw. Both colorways also come with Broc's new signature decals.

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.

A: Top Tube Length: 20.75″, 21" or 21.25″ – Learn what size is right for you here.

Check the size guide to see if its right for you..

Getting a top tube that is taller than suggested will make the bike feel more controlled and less responsive

Getting a top tube size that is smaller than normal will make the bike feel a lot more snappy and responsive.

B: Chain Stay Length: 13.25″ SLAMMED – Learn About Chain Stays Here

This is a long chainstay.

A short chain stay makes the bike feel twitchy. Spins will be easy, but airing and jumping might feel hard to control.

A long chain stay will make the bike feel really controlled. Spins will feel sluggish, but manuals and air tricks will feel nice because it will be more stable.

C: Head Tube Angle: 75.25° – Learn About Head Tube Angles Here

Steep head tube angles make the bike “snappy” meaning more responsive to fast turns.

A less steep head tube gives you more control.

D: Seat Tube Angle: 71°

E: Bottom Bracket Height: 11.625″

F: Stand over height: 9.25″

This is a tall standover.

A tall standover makes your seat higher up and will allow you to pinch it easier when learning barspins.

While a Small Standover will make it harder to bar but easier to whip

Broc Raiford Signature


The Darkwave frame is just a little more than most frames. For $359, you get a frame that can be put on almost any bmx bike. Now this price is a little more expensive than most Sunday frames. And I think that the $20 difference is just due to the fact that it is Broc's signature bike.

I'm also a little sad that they do not have a weight listed. Especially since most people use that as a big deciding factor when buying a frame. I can promise you that it will be over 5 lbs.


Overall, the specs on the Sunday Darkwave are amazing. It has bigger geometry which will make it feel more comfortable and flowy. If you are a really technical park rider, get something different. Otherwise, this frame will kill any street obstacle put in front of it.

A lot of well thought out quality decisions go into making these frames. (see highlights for more.) I'm sure that it will last anyone a long time, and it will hold up to a lot of abuse.

The Dusk color is absolutely sick. Way cooler than the Kink Cloud's color.
