The Williams frame is Nathan Williams’ first signature frame from Kink and features modern street geometry while retaining a classic look.
But still the frame features several subtle details that should not be overlooked. The steeper 75.5° headtube is responsive, and the short 12.75” chainstay length makes the frame nimble without compromising on tyre clearance; fitting up to 2.5” tires.
The double butted toptube and downtube with gussets on both ensure plenty of strength in the front end while the chainstay and seatstay bridge designs allot for generous tyre clearance while adding as much stiffness as possible.
Nathan’s frame of course comes standard with integrated seat post clamp, integrated chain tensioners to keep the wheel in place and removable brake mounts.
Additional details like the custom seat stay bridge badge inlay and interior dropout knurling round out both the good looks and serious functionality of the Williams frame.

NEED SOME HELP UNDERSTANDING FRAME GEOMETRY?
bmx frame geometry can look daunting but thanks to our handy guide below you will have it figured out in no time, and remember we're all bmxers here, so if you have any questions just ask.
Keep reading to find your perfect frame, or click below to watch the buyers guide video.
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 - 4ft - best suited to a 16" or 18" wheeled 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
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 and check out our sizing chart below!
HEADTUBE ANGLE (HT)
Headtube Angle (HT)
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 highspeed!
SEAT TUBE ANGLE (ST)
Seat Tube Angle (ST)
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.
CHAIN STAY LENGTH (CS)
Chain Stay Length (CS)
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 (SO)
Stand Over Height (SO)
Standover 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.
