Fit - 2021 Hartbreaker Frame

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.”
