Description

Introducing the Fit Heartbreaker Frame (Chris Harti), a signature ride that's as rugged and ready as the Australian outback. This limited edition camo frame isn't just a looker; it's designed by Chris Harti himself with a focus on stability and speed for those who love to ride fast and go big on the trails.

Every aspect of the Heartbreaker is crafted for performance. Thanks to the cleverly routed cables through the seat tube, you'll never have to worry about a noisy straddle hanger. The long chain stays paired with the 14mm drop-out slot expand your options for rear hubs, making this frame both versatile and economical. The single bend chain stays, straight stay bridges, and the traditional absence of a welded-on seat clamp all add up to a frame that’s both functional and classically styled for BMX aficionados who appreciate a nod to the past with every pedal.

Here are some standout features that make the Heartbreaker a top pick:
- Crafted with Butted Supertherm Top Tube and Straight Gauge Supertherm Down Tube for durability.
- Double gussets for added frame strength.
- Designed for up to 2.4″ tire clearance to handle even the roughest terrain.
- Innovative thru-the-seat tube cable routing for a cleaner setup.
- Proudly American Made with an engraved Heartbreaker logo on the head tube for a custom touch.

Specifications to note:
- Adaptable rear end length from 13.8″ to 14.5″.
- A laid-back head tube angle of 74.5° and a seat tube angle of 71°.
- A comfortably low BB height of 11.35″ and a standover height of 9.15″.
- Features Integrated head tube, Mid bottom bracket, and 14mm dropouts.

Whether you're tearing up the trails or just cruising around, the Fit Hartbreaker Frame (Chris Harti) is sure to keep the adventure going with a blend of modern performance and classic BMX style.

Top Tube Length - 21.25

20 inch BMX frame sizing

Frames are sized by top tube length. Start with your height, then let riding style decide where in the range you land.

Rider heightTop tube
147 to 157cm19.75 to 20.25"
157 to 168cm20 to 20.5"
168 to 175cm20.25 to 20.75"
175 to 183cm20.5 to 21"
183 to 190cm and up20.75 to 21.5"

The height bands overlap on purpose. If you land in two of them, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park. Plenty of riders, pros included, deliberately ride longer than a chart suggests.

How to measure

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the length of the tube you can see. Measure your current frame that way and compare.

  • Size up for stability through trails and transitions.
  • Size down if you want the bike quick and twitchy for spins and grinds.
  • Top tube is fixed once you buy, but chainstay length, stem length, fork offset and bar position all change how the built bike feels.
