Trialtech 16T Freewheel

108 Click
36 Click
72 Click

Sold out

  • Available with 36, 72 or 108 engagement points!
- 16 tooth freewheel from Trialtech, as featured on full-build Inspired bikes!
- Three (36 version), Six (72 version) or nine (108 version) high quality heat treated steel pawls are offset into groups of three into a tough 36 tooth ratchet, giving either 36, 72 or 108 engagement points per revolution.
- The bearing locking is also situated against the crank arm to keep it from coming loose - a nifty little feature!
- 72 & 108 versions use 4 large removal pockets that are also set into the other side of the freewheel: these do not stick out like tabs, which allows shorter bottom brackets to be run, and therefore better chain lines and increased chain life.
- 36 click version requires a 20 spline Shimano style bottom bracket tool for removal.
- 1.37" x 24tpi thread fits almost all hubs and cranks.
- 16T size only.
- 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: 165g

Overall Thickness: 17.56mm

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. If you wish to speed up this process, you can thin the grease down with light oil like GT85 or WD40, by spraying it between the centre and outer teeth of the freewheel and rotating it. Failure to bed the freewheel in correctly will void the warranty.

Hi, I'm looking to replace my ACS Claws 16t (approx 2004) freewheel and am unsure if this would be suitable - the hub is DMR Revolver on a 26". Also, which one do you recommend? Thanks

Hi Jonathan!
Most 16t freewheels tend to be a standard freewheel thread, with the 'micro drive' thread standard only really being used for 14t or smaller freewheels. As a result of that, the Trialtech freewheel should fit on there fine.
If you wanted to double check, you can measure the diameter of the threaded section for the freewheel. If your hub is 1.37" (just under 35mm) then this freewheel will fit. If it measures in at 30mm then you'll require the smaller micro drive sized freewheels.
If the Trialtech freewheel is compatible, then any of the 3 models we stock would work well! The more engagement points you have the more responsive it is, but it also tends to introduce a little more drag into the system due to the stronger springs inside the freewheel. For most applications this isn't a problem, but we have heard of some disciplines (e.g. cycle speedway and BMX race) to prefer a lower drag freewheel.
If you're looking to keep things on a budget the 36 Click freewheel is by no means a bad option. If you'd prefer a slightly higher engagement freewheel with minimal drag, the 72 Click option is ideal. Lastly, if you want the most responsive option, the 108 Click option would be the way to go.
All three are made with trials in mind, so they're nice and strong whichever model you choose.

Is this freewheel a good choice for race bmx?

Hi Erik!
These freewheels have relatively low drag compared to some of our other models, so should cause you to lose less speed when you're not pedaling.
They're nice and responsive and are built to handle the stresses trials places through them so for racing you shouldn't have any issues.
The only thing to check is your rear hub has a standard thread for the freewheel, but if your current freewheel is 16t or above then you should be fine.
If you have any more questions, please ask!

So I have this Haro Objekt 28" singlespeed in addition to my Onza Genesis and oh dudes this freewheel just kills every other fixie-singlespeeder in my town(little town in estonia). So loud and this special sound from 6 pawls comes as a bonus. On par with my CK ISO HD or a tiny bit louder. Of course if a friend of mine from work buys it too I must upgrade to 108p Ti one or something :)
