Fit Heartbreaker Frame

$509.99 $544.99

The Hartbreaker is Chris Harti’s long, low and laid back shred sled designed for going fast and big at the trails with stability. Cable routing thru the seat tube keeps your straddle hanger from slapping your down tube and works really well on this frame since the chain stays are pretty long. The 14mm drop out slot instead of the traditional 3/8” trail frame slot allow you a larger variety of affordable rear hubs to choose from. Single bend chain stays, straight stay bridges and lack of welded on seat clamp are all classic touches on this modern frame designed for timeless BMX riding.

“If you like travelling at high speeds and pulling back as hard as you possibly can while being in control, then the Hartbreaker might be the frame for you. It features a mellow 74.5° head tube, a low 11.35” BB height, and a nice 9.15” standover to match. Top it all off with a longer back-end you can trust and you got yourself a machine that’s ready for roasting, Oh! I had to make sure she was built like an ox too.” – Chris Harti

Just wrapped up a few days of touring around with @markmulville we hit as many local trail spots as possible in a 4 day period and unfortunately got rained on on our last day. We still had a blast. If you know Mark then you know he’s a beacon of light with endless positive energy. Keep an eye out for a @profile_racing / @circuit_bmx_shop Trails Edit in the near future. Here’s a shot from an evening sesh at @wethersfield_woods Thanks to @high_sodium401 for opening up the place for us. #circuitbmx #dudesinthewoodz
@elih401 getting loose on his new Rooster build. Keep an eye out for a pre book on another run of Circuit Frames this Fall/Winter. 📹 @houlesdoingthings #circuitbmx #walkerwoods #woodsman
If you spend a lot of time in the woods alone, you’re going to form some weird friendships with inanimate objects. The most durable dude in the woods has to be your “Barrow Buddy” I’ve been using mine for 15 plus years and he’s still going strong. Everyone needs a good push!! Thanks to Mr Zuppani for bringing my ideas to life. #circuitbmx #dudesinthewoods We also have some @drop_in_coffee available with buddy to get you stoked for those morning sessions.
