Monty Pro Race 135


Sold out

- Sealed bearing 135 engagement point freewheel from Monty.
- 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.
- Monty Pro Race graphics on the drive shell look great.
- 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 16t or 18t only.
- 16T is only for use on rear hubs by 'full sized' riders (weighing over 45kg) - use on crank arms by riders over this weight may cause the outer to break and this isn't covered by the warranty. This is the same for all 16T freewheels and it is due to the reduction in diameter of the outer ring. For kids' bikes, these can be used on the cranks no problem.
- Weight: 175g (18t)

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.



Can this freewheel be srcewed on the rear trialtech hub of my inspired fourplay pro 2015? If so, do I need any spacer?

Hello - This would fit (and you wouldn't need any spacer), but it would make your gear ratio feel lighter as the Fourplay would usually have a 16t freewheel fitted on the rear. Thanks, Mark

Hi! I use an old-style echo urban crank, urban rockring and a WI eno trials freewheel. Can I replace the FW to this kind of Monty, using a spacer, considering the thickness? Thank, Tamas

Reply from TartyBikes on 10/06/2016

Hi Tamas - This should work fine. You should be able to use the Monty freewheel without a spacer too due to the design of the Urban bashring featuring an integrated lip/spacer near the base. Thanks, Mark


Hi, I have a Onza Vox with the cranks that came with the bike. Think itís t-pro cranks would this free wheel fit my cranks? Thanks for your help

Hi Matt - This freewheel should fit your Vox fine. It can be tricky getting freewheels off, but we have a video on removing freewheels in our 'Media' section if you need any help! Thanks, Mark
