Introducing Gary Young's signature Wavelength frame.
With a longer rear end and top-tube options, this frame is designed for riders who love to go fast and want a more stable ride for trails and transitions.
Features
- Gary Young Signature Geometry
- 100% 4130 chromoly frame
- Removable U-brake hardware and Gyro tabs
- 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.

Can’t be beat for the price
Size: XX-Large, Color: Blue
Can’t beat it for the price, I was at super fancy NYE party. Lots of guys in very expensive jackets asking me where I got mine, this jacket got tons of compliments and looked great in photos. Quality was higher than I figured it would be for this price point. Go one size up, I am normally an XL, I ordered XXL and fit perfect.

Good jacket for the price
Size: Small, Color: Gold, Size: Small, Color: Gold
My son had prom and the theme was, "Your Night to Shine," so he and his girlfriend decided they needed to SHINE. And when this boy picks for a theme, he picks!
He is 5'11 150 lbs, very thin, but also muscular and ordered a small. The sleeves were a bit short on him, but that's to no fault of the jacket, it's just been his life as a tall, lanky kid. Great quality, steamed the creases out easily, and stayed together the entire evening.
Excellent buy!

Great for the stage. A bit iffy up close.
Size: Medium, Color: Silver-3
Jacket is decent. It’s good for the stage. It looks a bit cheap up close. Probably good for prom but for an adult wearing it to a function I can’t say I would recommend it. But it’s great for the stage! We have worn them many times and they hold up well. I’ve even washed them in the washing machine on delicate cycle without any problems. Just hang it to dry and you’re good to go. It holds it shape and doesn’t wrinkle. A good value for the money. The sequences are this color as they are shown. The sizes are true to fit.
