  • 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.

Questions

Harry Nicholls

Will this fit on the base model inspired flow 24?

Posted by Harry Nicholls

Reply from TartyBikes

Hi Harry - This should fit the Flow 24" bike fine. It's almost a like-for-like replacement. Thanks, Mark

Adam

Does this have 4 pawls with the 72 engagement points?.

Posted by Adam

Reply from TartyBikes

Hi Adam - The 72-click freewheel uses 6 pawls. The 108-click uses 9. Thanks, Mark

Oded

Hey, cool guys of tarty. You guys rock! Q: would the freewheel with the 108 engagements, fits to ozonys v4 (isis bb). What makes the 108 better than the 72? Thanks again, Cheers! Oded

Reply from TartyBikes

Hello - The 108-click freewheel has 36 more engagement points than the 72-click model, so it offers a higher level of performance by being more responsive. That said, we don't recommend them for use as part of a front freewheel setup. 16t freewheels have a reduced diameter compared to 18t freewheels, so it makes them much more prone to snapping. For this reason we suggest using an 18t at a minimum. Thanks, Mark

Scott

Hi guys I was wondering what the reliability of the 108ep version is like? I know a few guys who run the 72ep version and are really happy with it, I know the 18t 108ep has had some issues and wanted to know if the 16t is as reliable as the 72ep version.

Reply from TartyBikes

Hi Scott - This version of the freewheel uses upgraded springs so they have quite 'positive' engagement. We haven't heard any long term reviews yet but the improvement to the engagement should bode well for them. Thanks, Mark

Tomas

hello is compatible with the onza rip ?

Posted by Tomas

Reply from TartyBikes

Hi Tomas - yes, this would fit your bike just fine. Thanks, Flipp.

Yevgen Nabokov

Hello! I've got this freewheel from Tarty few days ago for using on my hub. I know that it requires to be carefully bedded in so I tried to ride it smoothly. It started skipping even on small load and I desided to stop before I'll damage it's internals. I'm trying to disassemble it to remove grease and see if it is ok. But it's cap holds very tight. Tell me please am I right that this cap unscrews in anticlockwise direction?

Posted by Yevgen Nabokov

Reply from TartyBikes

Hi Yevgen - thanks for your question. Yes, that is correct - the lockring unscrews anti-clockwise. Thanks, Flipp.

bruce

Hello, is this for 1/8 or 3/32 chains?

Posted by bruce

Reply from TartyBikes

Hi Bruce - thanks for your question. This will work with both widths of chain with absolutely no problems. Thanks, Flipp.

Sean Jenkins

Hello, I'm new this game and was wondering would unit do as a replacement for a Long YIH LY-18T8, if not what would recommend. Thanks

Posted by Sean Jenkins

Reply from TartyBikes

Hi Sean - thanks for your question. This will fit on your hub/cranks, yes, though it is worth pointing out that this is a 16 tooth freewheel, where the Long YIH is an 18 tooth. This means it will affect your gear ratio. We stock many models of 18 tooth freewheels if it is one of those that you are after (it will say in the product descriptions how many teeth each model has). Hope that helps. Thanks, Flipp.

Christian Jones

Hello Tarty, First off,thanks for the amazing customer service on my last order,cheers! Will this work on my Inspired Element 24"? Are there other options any stronger as I have a reputation of thrashing my parts. Thanks!

Posted by Christian Jones

Reply from TartyBikes

Hi Christian - that's no problem, thanks for the feedback! This will work absolutely fine on your Element, since it's the same as the one it came with! These are good freewheels, and so are probably your best bet. Hope that helps. Thanks, Flipp.

Zoster

Hi! what does " by 'full sized' " mean?

Posted by Zoster

Reply from TartyBikes

Hi Zoster - thanks for pointing that out. It should have read "by 'full sized' riders", meaning it's Ok for small riders/children to use on the crank. We've fixed this now. Thanks, Flipp.

Andrew

will this work on my hope pro 2 hub?

Posted by Andrew

Reply from TartyBikes

Hi Andrew - You don't need a freewheel and a freehub as they are different options for doing the same job. You only need one or the other. If you have a Pro2, you just need a sprocket on the front and rear. Thanks, Flipp.

single speed commuter epic transformation...

Posted by Indrek

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 :)

Reply from TartyBikes

Hello - Thanks for the detailed review, it's nice to hear you're happy with your new freewheel!
