Description

Direct mount Oval BB30 chainrings are designed for Sram Short BB30 spindle cranks (9.1mm axle spacer on drive side) Oval chainrings work because a rider does not produce power evenly through a pedal stroke; they maximize the part of the stroke where power is produced and minimize resistance where it isn't. Oval rings make the spin cycle a lot smoother and are easier on legs while climbing. Believe it (or not), but a round chainring doesn't transfer torque to your rear wheel as smoothly as an Oval one. You will actually feel your stroke to be more "round" with an Oval shape than with a round chainring.
Why it matters ? Traction, Traction and Traction. With oval rings, rear tire traction improves greatly on loose and slippery terrain. Your legs will be less tired and your speed improved. Climbing will become easier then ever before. It is world's best oval chainring.

  • Chain options : 10, 11 or 12 spd 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 for very aggressive enduro riding it is recommended to use an upper chain guide or at minimum bashguard.)
  • Oval chainring does not affect the work of rear dérailleur cage at all (video here). Such a ring can be used therefore in 1x9/10/11 combination as well as Singlespeed and fixie bikes
  • Chain Length : Bypassing the rear derailleur, run the chain around front chainring/largest cog combination. (For the full suspension frame, position the rear suspension for the greatest chain length required. It's usually a normal position where rear shock if fully extended) Add 2 to 4 segments of the chain to this length for proper chain length.
