Tech Talk: Cannondale Bad Habit

Cannondale Bad Habit
Plus bikes are hot, not just because they are the new, shiny bikes on the display window but because they really work for a lot of riders. The extra traction and cushioning of the big tires at low pressure helps riders ride safer, go faster and have more fun. The all-new Bad Habit Carbon takes the spot-on trail manners of the Habit and supercharges them with 27+ wheels to create the ultimate technical trail bike. The Ai offset drivetrain delivers super short chainstays for superior traction and tons of clearance for full 3.0 tires.

Swallow 3.0 tyre
The Bad Habit Carbon gets the latest Cannondale racing tech featuring lightweight BallisTec carbon, SmartForm C1 swingarm, Boost 148 rear axle and a super light carbon link. A 68 degree head angle and 74 degree seat angle are spec’d here. Chainstay is 17.4 inches and that is pretty good for a bike that can take a full 3.0 tire. Bottom bracket height is a low 13.1 inches so this will carve up terrain nicely. Putting a smaller 2.8 tire will improve handling but will put the bottom bracket at 12.9 making tech climbs more difficult.

No pivot here
Key to the new frame design is its aluminium flex-stays. Instead of having pivots at the dropouts, the seatstays are tuned to bend vertically, which allows the 120mm-travel suspension to cycle without binding. This ‘Zero Pivot’ design also adds rigidity and saves weight. Up front, the Habit frame uses a straight oversized head tube to accommodate the 1.5in steerer of the one-legged Lefty fork. Internally, the latest generation has updated Trail+ damping and revised controls, including a lock-out button for climbing. This Lefty uses a single 44mm upper leg and 32mm slider, and requires a dedicated hub.




Highlight:
  • Updated Lefty fork
  • 3.0 tyres
  • Carbon frame with aluminium swingarm
  • Quick release
  • Boost 148 rear axle



Glossary:

Bottom Bracket: The bottom bracket on a bicycle connects the crankset (chainset) to the bicycle and allows the crankset to rotate freely. It contains a spindle that the crankset attaches to, and the bearings that allow the spindle and cranks to rotate. The chainrings and pedals attach to the cranks. The bottom bracket fits inside the bottom bracket shell, which connects the seat tube, down tube and chain stays as part of the bicycle frame.

Chainstay: Tube connect BB housing with rear end

To provide the extra clearance needed for fatter tyres, the frame uses a . Oversized BB30 and expanding collet hardware on the main pivot and shock linkages increase frame stiffness too. Rather
