Overview
This is a carbon fiber frameset built around a 451 rim, 20 inch wheel platform for disc brake, thru axle builds. It ships as frame, fork, carbon seatpost and axle levers only, aimed at riders building or upgrading a small wheel road or BMX-style bike.
Despite BMX and road bike both appearing in the listing, the specs point to a small wheel disc brake frameset rather than a stunt BMX frame: thru axle hubs, a threaded 73mm bottom bracket and internal routing are road and gravel conventions scaled down to a 451 rim. Buyers need disc brake, thru axle wheels already in hand, since this frame will not accept rim brakes or quick release hubs.
- 451 rim frameset sized for 20x1-3/8 tires
- Thru axle 12x100mm front, 12x142mm rear
- Disc brake mounts, F70mm/R34mm
- Carbon fiber frame, fork and seatpost
Who it's for
Riders assembling a custom small wheel, 20 inch, 451 rim disc brake bike who already own or are sourcing thru axle wheels, a matching headset and disc brake calipers. Not a fit for anyone wanting a complete, ready to ride bike out of the box.
Strengths and trade-offs
Drawn from this product's published specifications.
- Full internal routing keeps cables protected and tidy
- Thru axle front and rear for wheel stiffness
- Carbon seatpost and integrated locker included in the package
- Bottle cage mounts for longer rides
- Frame only, no wheels, drivetrain or brakes included
- Requires disc brake and thru axle wheels only
- No fitment guidance beyond stated dimensions
Performance notes
The carbon fiber construction keeps the claimed frame weight near 1413 grams with the fork adding roughly 476 grams, so the appeal here is a lighter build than a stock steel frameset. Internal routing and a direct mount front derailleur point to a build meant for clean cable runs rather than easy field repairs.
