If you want a street frame that’s clean, modern, and built around real-world tech riding, the Kink Williams frame hits every mark.
Yes, you guessed it right, this is the very Nathan Williams’ first signature frame.
But it’s been around for a good minute, and we all know why.
Because it ROCKS!
The frame is dialed for modern street geometry with a 75.5° head tube angle, short 12.75” slammed chainstay, and a classic – but sharp – look.
But this frame goes way deeper than just good frame geometry.
It’s got details you won’t find on most frames:
- interior dropout knurling,
- chainstay/seatstay bridges designed for stiffness and tire clearance,
- and a CNC’d seatstay bridge with a brass badge inlay.
Made from 100% seamless Sanko 4130 chromoly, the Williams is all about strength, responsiveness, and epic detail.
Let’s investigate it further.
Kink Williams Frame Review
1. Key Features Of The Kink Williams Frame
Nathan didn’t just slap his name on this BMX street frame.
He wanted to build it with the same attention to detail he brings to his riding.
And we all know how much attention to detail that is.
A. LOT.
Every feature here reflects what real street riders ask for: strength where it counts, clean design, and geo that moves exactly how you want it to.
- Nathan Williams’ signature frame
- Adjustable 12.75” slammed chainstay for snappy response
- Steep 75.5° head tube for tech front-end control
- Double-butted top- and downtube gussets for strength
- Custom CNC’d seatstay bridge with brass badge inlay
- Interior dropout knurling to grip axles/guards better (handy detail!)
- Removable brake mounts (also drilled head tube for gyro tabs)
- Investment cast dropouts with integrated chain tensioners
- Tire clearance for up to 2.5” tires (hey, Nathan’s signature Cinema tires are 2.5″)

4. How The Kink Williams Frame Feels
This frame rides fast, snappy, and centered.
The steep head tube and short chainstay combo make nose tricks and hop tricks feel responsive without losing control.
Manuals feel balanced, spins feel tight, and the whole setup just responds how you want it to.
It’s stiff without being harsh, and the added detail, like the internal knurling and investment cast dropouts, makes a difference when you’re slamming your wheel back or grinding heavy.
Moreover, the slightly higher 11.7″ bottom bracket height ensures additional tweakiness and clearance for regular and opposite crooked grinds.
Whether you’re running 2.35″ or full 2.5” tires, this thing clears without rubbing.
And if you get the Kink Williams fork, you don’t have to worry about your tire rubbing in the front either.
It’s subtle where it should be and built tough everywhere else.
The only improvement I’d make to the next version of the Williams frame is to lengthen the standover height.
This doesn’t necessarily do much to the overall performance, but it does make the frame look MUCH better.

- No built-in seat clamp – though it has an integrated one, some still prefer the classic clamp – but I like the integrated one, though.
- Not designed for brakes out of the box (mounts are removable) – hey, Nathan rides brakeless, that’s why.
Not really a con, but would love to see this frame available in 21.5″ top tube length as well.
Some of us just like larger frames, even though we aren’t super tall.
6. Who The Kink Williams Frame Is Best For
- Street riders who ride hard, grind a lot, and want tech-focused geometry
- Riders who want premium details like investment cast ends, gussets, and tensioners
- Anyone looking for a snappy, clean, and modern street geometry frame that can take abuse
- Obviously, Nathan Williams fans!
