Sunday Silvawave Frame

$409.99

New for 2024 - Brett Silva's signature SILVAWAVE frame.

Known for his upbeat energy, dipping a mean toboggan, dropping great video parts and winning Silver at X Games Real BMX Best Trick and more, it was only a matter of time before Brett got to call the shots. From colorway to dimensions, the Silvawave is the frame Brett wants.

The Silvawave is 100% 4130 chromoly, and features Sunday’s signature dent-resistant wave down tube to give riders a little extra peace of mind when sessions don’t go according to plan. Additional refined details like an integrated seat clamp, tapered stays, removable brake hardware, hollow dropouts and integrated chain tensioners can also be found on the Silvawave.

Brett's preference in geometry provides a stable 75° head tube angle, a longer 13.45-13.70” chainstay, and a tall 9.5” standover to give it the proper ride-feel that builds confidence at speed. All this makes the Silvawave an affordable and versatile signature frame that’s designed to handle Brett's burly riding style when he's ON A TEAR and much more.

Features

  • 100% 4130 chromoly frame
  • Brett Silva signature geometry.
  • Removable U-brake hardware and Gyro tabs
  • Integrated seat clamp
  • 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.
  • 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.
  • 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.

Just wrapped up a few days of touring around with @markmulville we hit as many local trail spots as possible in a 4 day period and unfortunately got rained on on our last day. We still had a blast. If you know Mark then you know he’s a beacon of light with endless positive energy. Keep an eye out for a @profile_racing / @circuit_bmx_shop Trails Edit in the near future.  Here’s a shot from an evening sesh at @wethersfield_woods Thanks to @high_sodium401 for opening up the place for us. #circuitbmx #dudesinthewoodz

If you spend a lot of time in the woods alone, you’re going to form some weird friendships with inanimate objects. The most durable dude in the woods has to be your “Barrow Buddy” I’ve been using mine for 15 plus years and he’s still going strong. Everyone needs a good push!! Thanks to Mr Zuppani for bringing my ideas to life. #circuitbmx #dudesinthewoods  We also have some @drop_in_coffee available with buddy to get you stoked for those morning sessions.
One way or another you know @codydiggs will be ripping lips!! Surfs up in the back woods of RI. #circuitbmx #endlessdeah #dudesinthewoods
