Description

The 3rd version of the Sunday Soundwave frame, is the most advanced frame design that Sunday offers. It's 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 and Brett Silva.

Features
  • 41-Thermal heat treated for life. Sunday's post weld heat treating keeps the frame light and strong, backed by a lifetime warranty against bending, cracking and breaking.
  • Wave top and down tubes. Double-butted 1.375" and 1.45" tubes use proven Wave shaping to fight the dents that shorten a front end's life.
  • Boxed chainstays clear big tyres. The boxed shape fights denting and allows a shorter rear end while still clearing 2.35" to 2.40" rear tyres.
  • Machined and finished throughout. Post-weld machining of the bottom bracket and head tube, a cable channel guide and a Director style wishbone tidy the whole frame.
  • Angled removable brake mounts. Hollow dropouts with integrated chain tensioners and removable mounts let you run a u-brake or strip it right back.

20 inch BMX frame sizing

Frames are sized by top tube length. Start with your height, then let riding style decide where in the range you land.

Rider heightTop tube
147 to 157cm19.75 to 20.25"
157 to 168cm20 to 20.5"
168 to 175cm20.25 to 20.75"
175 to 183cm20.5 to 21"
183 to 190cm and up20.75 to 21.5"

The height bands overlap on purpose. If you land in two of them, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park. Plenty of riders, pros included, deliberately ride longer than a chart suggests.

How to measure

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the length of the tube you can see. Measure your current frame that way and compare.

  • Size up for stability through trails and transitions.
  • Size down if you want the bike quick and twitchy for spins and grinds.
  • Top tube is fixed once you buy, but chainstay length, stem length, fork offset and bar position all change how the built bike feels.

Not sure? Tell us your height and how you ride, and we will tell you what we would put you on.
