Comas 135.9 Sealed

  • Sealed bearings for ultimate outer shell stability!
  • 135 engagement points makes it super responsive.

- Sealed bearing 135 engagement point freewheel from Dani Comas' own trials brand Comas.
- 135 engagement points are achieved by using 3 offset groups of 3 pawls into a 45 tooth ratchet.
- Each pawl is actuated with an individual spring, giving precise, reliable engagement.
- Dual sealed bearing design gives great driveshell stability, as well as allowing a unique design that requires no lockring (the bearings are held in place using an external circlip), helping to save weight. Please note that this produces more 'drag' than a regular single speed freewheel.
- The freewheel width is kept to a minimum to by using BB-style removal tabs - this means the freewheel can be removed with a Shimano-style 20 spline bottom bracket tool.
- Please note: You must use a freewheel spacer between the freewheel and the bashring (or crank arm if you aren't using a bashring), unless you are using a bashring with a wider section/lip at the base.
- 1.37" x 24tpi thread fits almost all hubs and cranks.
- Available in 18t only.
- Weight: 175g

Freewheel width: 18.90mm

This freewheel must be bedded in before trials use, to ensure any excess grease used when assembling the freewheel works away from the mechanism. You can do this by riding the freewheel around 'normally' for a few hours, both freewheeling and engaging the mechanism gently. If the freewheel is subjected to trials use without having been bedded in, the pawls will not engage correctly and this causes the freewheel to skip, damaging the pawls and ratchet. Failure to bed the freewheel in correctly will void the warranty.

Additional Information

Please note that this freewheel MUST be bedded in with 'normal' riding before trials use. We also recommend thinning out the grease inside this freewheel after the bedding in period, since the sealed bearings will expel any excess grease when new and this will enter the pawl mechanism.

Freewheel sound level:

All freewheels tested under similar conditions. Please note that the sound level of a freewheel may change after bedding in. A 10 dB increase in sound level is approximately equivalent to double the perceived volume.
