Stacked official word:
When your riding progresses, your frame needs to keep up. That’s exactly where the Sunday Soundwave Frame stands apart. Designed using advanced engineering and real rider feedback, this frame delivers next level durability, responsiveness, and confidence for modern BMX riding.
First, Sunday developed their exclusive Soundwave tubing technology to solve one of BMX’s biggest problems, frames breaking at stress points. As a result, riders get a frame that is stronger where it matters most without adding unnecessary weight.
Whether you ride street, park, or technical setups, the Soundwave frame provides a balanced geometry that feels stable during high speed lines yet responsive during manuals, spins, and grind combinations.
Additionally, reinforced tubing helps absorb repeated impacts, meaning you spend less time worrying about equipment and more time progressing your riding.
Unlike stock BMX frames built for entry level durability, the Sunday Soundwave Frame is engineered for riders who push limits every session.
👉 So if you’re ready to upgrade reliability, control, and long-term performance, the Sunday Soundwave Frame is built for you.
Available now at Stacked BMX, rider owned, rider tested, rider approved.
Sunday word:
Incredibly strong, lightweight and high-tech. The 3rd version of the Sunday Soundwave frame (v3), is the most advanced frame design that Sunday offers. Loaded with features like proven hollow dropouts, integrated chain tensioners, Wave down tube and top tube, cable channel guide, angled removable brake mounts, "Director" style wishbone, post-weld machining of the BB & HT, and full 41-Thermal post weld heat-treating throughout. The Soundwave v3 is backed by THE unparalleled 41-Thermal LIFETIME WARRANTY against bending, cracking and breaking. And it is the go-to frame for team riders like Gary Young, Chris Childs, and Brett Silva.
Key Features
• Sunday Soundwave tubing for increased frame strength
• Heat treated chromoly construction
• Modern street & park geometry
• Reinforced high stress areas
• Designed with professional BMX rider input
5 Reasons Stock BMX Frames Fail
• First, stock frames often use lower grade tubing to reduce production costs.
• Additionally, weld areas are rarely reinforced, leading to cracks over time.
• Because geometry is designed for general riders, stability suffers during advanced tricks.
• Stock frames typically lack heat treatment, reducing long term durability.
• Finally, repeated impacts from drops and grinds create stress fatigue much faster.
5 Reasons the Sunday Soundwave Frame is a Better Solution
• Soundwave tubing technology strengthens the frame at critical stress points.
• Heat treated chromoly increases lifespan under aggressive riding.
• Modern geometry improves balance, control, and trick consistency.
• Reinforced rear triangle handles grinding and hard landings better.
• Proven pro level design trusted by serious BMX riders worldwide.

41-Thermal Processed (Lifetime Replacement Warranty):
Sunday is the only company to use Odyssey's proven and trusted 41 Thermal heat treating. This formula has been refined and improved since the late 90's. The proven 41 Thermal process allows the products to be lightweight AND strong. It is also backed by a legendary lifetime replacement warranty against bending, cracking, and breaking.
Wave Top Tube:
Top tube dents will significantly weaken the front end of your bike, thus shortening it's life. The double-butted, 1.375" diameter top tube with proven Wave shaping helps fight denting.
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.
Tapered Chain & Seat Stays:
Both chain and seat stays taper to provide a refined and clean look to the frame while still providing strength. The are both angled on the inside for improved chain clearance and weight savings.
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.
Boxed Chainstays:
We've updated the chain stays with a "boxed" tube shape that helps fight denting. The new shape enables the frame to have a shorter rear end as well providing clearance for larger sized rear tires. It's not uncommon to see 2.35" - 2.40" tires in the rear on a Soundwave.
Post Weld Machining:
The Mid BB and Headtube is machined to its absolute minimum without sacrificing strength or durability. The machining happens after welding for a precision bearing fit.
Integrated Head Tube:
The integrated headtube is machined to its absolute minimum without sacrificing strength and durability. The machining happens after welding for a precision bearing fit.
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 place as well as simplify wheel removal.
Director Wishbone:
Slimmed-down Director style wishbone is lighter and significantly stronger than previous versions.
Removable Brake Hardware:
Refined removable brake mounts and cable channel improvements that provides benefits with or without a brake setup.
Rust Proof Coating:
All Sunday frames are rust-proofed with "Black Magic" coating before the final finish is applied. It is lightweight and the best anti-corrosion processing that's offered today.
