The Heckler’s boundaries aren’t defined by distance, laps, or time. The boundaries in our head that say, “Don’t bother”, “Turn back”, “Impossible.” Smashing these boundaries is what got us hooked on riding in the first place. Heckler’s not about taking things easy, it’s about making things possible.

• Chain options

  10, 11 or 12spd chain for geared bike or 6-8 spd for SS. If used in 1x9 drivetrain - 10spd chain must be used to obtain the performance. (yes - 10spd chain will work great on 9spd cassette)

• Chainguide needed?

  No. But if you want one then chain guide should have 2 teeth more capacity than nominal oval ring size.
