Fit Heartbreaker Frame (2023) - Chris Harti Signature



The new Fit Heartbreaker frame is here!

Rolling long and strong is the 2023 version of Chris Harti's signature Fit Heartbreaker frame is here!

Built with the same badass specs as his first version Fit Hartbreaker frame, the 2023 Fit Heartbreaker adds some new graphics, new looks and new colours, as well as an 'E' added to the name.

Forever stoked to see Back Bone BMX team rider Chris Harti rolling on his own signature frame!

"If you like travelling at high speeds and pulling back as hard as you possibly can while being in control, then the Fit 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

Super stoked with the heartbreaker frame, super flowy at the trails and fast and lofty in the bowls. Big ups!
