Sunday Soundwave V3 Frame

Incredibly strong, lightweight & high-tech.

The third version of the Sunday Soundwave frame, is the most advanced frame design that Sunday offers. It's loaded w/ features like proven hollow dropouts, integrated chain tensioners, Wave down tube & top tube, cable channel guide, angled removable brake mounts, "Director" style wishbone, post-weld machining of the BB & HT, & full 41-Thermal post-weld heat-treating throughout.

The Soundwave v3 is backed by the unparalleled 41-Thermal Lifetime Warranty against bending, cracking & breaking.

Key Features:

• 100% 4130 Chromoly Frame
• 41-Thermal Processed (Lifetime Warranty):
  Sunday is the only company to use Odyssey's proven & trusted 41 Thermal heat treating. This formula has been refined & improved since the late 90's. The proven 41 Thermal process allows the products to be lightweight & strong. It is also backed by a legendary lifetime warranty against bending, cracking, & 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 w/ 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 & whatever else happens to get thrown at it.
• Tapered Chain & Seat Stays:
  Both chain & seat stays taper to provide a refined & clean look to the frame while still providing strength. The are both angled on the inside for improved chain clearance & weight savings.
• Miter Cut Top Tube:
  A miter-cut top tube creates a precise joint w/ 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 w/out 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 w/out sacrificing strength & durability. The machining happens after welding for a precision bearing fit.
• Hollow Dropouts w/ 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 & significantly stronger than previous versions.
• Removable Brake Hardware:
  Refined removable brake mounts and cable channel improvements that provides benefits w/ or w/out a brake setup.
• Rust Proof Coating:
  All Sunday frames are rust-proofed w/ "Black Magic" coating before the final finish is applied. It is lightweight & the best anti-corrosion processing that's offered today.
