-
With younger BMX riders continuing to progress at a rapid pace, having a strong and agile frame for them is needed more than ever. Enter Sunday's Ranger 18" Frame.
Built with many of the legendary features found on Sunday’s aftermarket designs, this full chromoly frame offers a short chainstay for maneuverability and pro-level frame geometry that rides like a scaled down 20" bike. The Ranger 18" is the perfect frame for any serious rider in this size range.
Features
- 100% 4130 Chromoly Frame
- Proven pro-level geometry adjusted for 18” wheels.
- Integrated seat clampButted Seat Tube & 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.
Removable Brake Hardware: - Proven, removable, brake mounts and cable guides/stops work flawlessly when installed and allow for a sleek overall look when they’re not.

FRAME SIZE CHART
Frame sizing is very much a personal preference: some riders like them longer, others shorter. Here's a rough guide - if you have any questions remember we are here to help!3ft - 3ft 8" - best suited to a 16" BMX bike
3ft 8" - 4ft - best suited an 18" BMX bike
4ft - 5ft - 18" to 20" top tube
5ft - 5ft 4" - 20" to 20.25" top tube
5ft 4" - 5ft 8" - 20.25" to 21" top tube
5ft 8" - 6ft - 21" to 21.25" top tube
6ft plus - 21" top tube or longer
| Rider Height (in) | Rider Height (cm) | Top Tube Length |
|---|---|---|
| 5' | 152 | 20" |
| 5'3" | 160 | 20.5" |
| 5'6" | 167 | 20.75" |
| 5'9" | 175 | 21" |
| 6' | 182 | 21.25" |
| 6'6" | 200 | 21.5" |
FRAME GEOMETRY
Frame geometry can take a bit of understanding - but here at SourceBMX we are here to help! The first thing to understand is that BMX frame sizing is best measured by the length of the top tube - shown here as TT. Keep reading on to understand how the angles change how your frame will feel!
Head tube angle determines the angle of your forks. A steeper HT (i.e 75°and higher) will make the bike turn quicker than a mellower angle (i.e 74.5 and lower°). The more responsive the frame, the more twitchy it will feel, especially at high speed!
Seat tube angles don’t vary too much (around 71°) and affect the centre of gravity. The steeper the angle, the shorter your bike will feel. Some frames have a mellower seat tube angle (example 69˚) which makes for a longer frame without actually being longer and reduces how fast your frame turns.
The chain stay is essentially the length of the rear end of the bike. A shorter CS length will make the bike more responsive and a longer one more stable. As a rough guide a 13.5" long chain stay is about average.
Stand over height is essentially how high your frame is. A frame with a low standover height is more responsive and easier to 'throw around' whilst a high SO height is more stable; particularly useful when going fast.
