Frame Geometry
A: Top Tube Length: 21″ – 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: 13.2″ – 13.5″ – 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° – 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: 11.5″
F: Stand over height: 9″
This is a tall standover.

G: Rise: 9.5″
Riding a tall rise, will give you more leverage on the bike. Making it easier to pull back and lift the front wheel up.
H: Width: 29″
This is a wide width.
Narrow bars make barspins easier.
Wide bars give you more control and stability when steering.
I: Backsweep: 11º
What does backsweep do?
As far as I know, there is a sweet spot for backsweep. Too much will make the bike feel weird, and too little will make the bike unstable. It seems like the sweet spot is around 11º to 12º. If you need something a little more aggressive and straight feeling, go for 10º, but only do this if 11º is uncomfortable.
J: Upsweep: 1º
This is a normal upsweep!
What does upsweep do?
There is a lot of discussion about 1º upsweep vs. 4º upsweep. Some people are running experiments and testing if the greater upsweep will make drops feel better. It seems like a lot of street riders run 4º to 5º upsweep. This helps for wrist pain and lessens the impact of big drops.
Price
This is the most expensive bike in Sunday’s 2021 line. The Sunday Soundwave special comes with the signature Sunday Soundwave frame and a ton of aftermarket parts. It costs a little over $1000 which is so so so expensive for a complete bike. However, the people that end up with this bike are generally really happy because they love the quality and the smooth ride that it provides.
Quality
It would just be easier to list the things on this bike that are low quality. Unfortunately, there’s nothing low quality about this bike. My favorite thing about it is that the frame Forks bars and cranks come with a lifetime warranty because they are such high-quality aftermarket parts. Obviously this bike includes double-wall rims heat-treated parts and sealed bearings. This is the same quality that riders like myself ride. It will withstand very high-level tricks and high-level crashes.
Buy if you are learning:
- 360
- bar spins
- Grinding handrails
- high-level street
- high airs
- 540
- grind combos
- tail whips
Don’t buy if you are learning:
- Good for any trick
Conclusion
So basically if you have the kind of budget to afford this bike, you could get away with buying a fully custom bike. Or at least pretty close to it. You’ll get the same quality but you’d be able to customize the parts to exactly what you want. With that being said, this is a really good bike with really good quality. It’s perfect for a rider who’s writing at a mid to high level and who needs a bike to withstand some abuse.
This bike is very well-rounded meaning that you will be just fine riding it on park, dirt, or street. Just make sure that this is the right top tube size for you because it would really suck to spend this much money on a bike that doesn’t necessarily fit.
