The Heartbreaker Crankset is our take on a slim arm compact double. We drew from the classic Sugino Ritchey Logic cranksets to get the slim arm profile with a high offset. The high offset in the arms makes it so you can run a shorter bottom bracket than with most square taper cranks. This is nice when you're running it on a frame with wide chainstays like an Evasion or Wombat (set up 1x) as it keeps your chainline nice and tight which promotes good shifting and keeps drivetrain wear to a minimum. Aesthetically it'll give a smoother seamless look since you wont have to run a super long bottom bracket. The crank comes with a set of bolts and self extractor caps. Be sure to install the included plastic washer between your extractor cap and bolt.
Chainline with 110mm Bottom Bracket= 47.5mm
Q-Factor with 110mm Bottom Bracket in a 68mm BB Shell= ~155mm
