Need assistance with replacing ratchet ring on V2 Kickr

I have been riding my V2 Wahoo Kickr for about 3 years now and have recently found out that my ratchet ring is broken. For those of you that don’t know what that is, it is the ring that the paws of the hub uses to turn the wheel in a bike and the flywheel on these trainers.

So in saying that, I am looking for help in getting this repaired some how. Wahoo support says that due to the age of this trainer they don’t support servicing or repairing it. Other than that ratchet ring, this is a very healthy trainer. Only has about 3k KM on it.

Any help will be appreciated.



First step is to see if you can identify the specific ratchet ring installed. Get the freehub off, clean all the grease off and get a good look (and pic) of the ring. It might be one of the common styles, where you can order the ring tool and replacement. Below is a quick search result showing a range of possibilities. See if you can match yours and get the appropriate tool and ring to fix them.

Thank you for your reply,

I have been looking at these for about a week. I even looked at the wahoo site. They actually have the ring for a 2018 model and was looking at getting that one and seeing if it would work. The tech at kickr says that this ring is not replaceable but there are groves under the ring where it was screwed in. They don’t want to do anything but sell me a more modern one. I don’t have the money for it right now… will be cheaper to just get this one fixed. There is nothing wrong other that that ring.



Depending on what your local bike shop has, they may have the removal tool. Could be worth taking the trainer there (if that is possible for you) to see if they can do the work to remove the bad one. Then identify the exact right one to replace and order that.

I will do that tomorrow… I can’t move forward until that ring is out…

Hope you figure this out!

I’ve replaced the bearings in my Kickr Gen 1 twice now but haven’t replaced the one blocked by the ratchet ring since it didn’t look removable.

Haven’t had time to remove the broken ratchet ring. It is surely removable or it is sure broken up. And if it is not removable, I will have to replace the flywheel… @#$%!

I will get to it tomorrow…


Hey, I’ve got the same issue with my 2018 kickr. Any luck finding the right tool. So many to chose from and I can’t figure hue correct one!

What bearings are they, meaning size? And do you have any photos of the process?

Sorry just saw this. The bearings in the Kickr, at least in my gen1 are…

2x 6002-2rs

2x 6201-2rs

2x 6003-2rs

These are the only pics I took last time I swapped the bearings, I’ll take more next time as I think I’m really needing to replace the one behind the freewheel pawl now.

The ratchet ring may be replaceable, but you might break your tool and vise trying to get it out. I broke a harbor freight vise trying to remove a DT Swiss 370 ring.

If you do get the tools, get the “Polish” ones from ebay, not the CN ones. I’m not sure on the origin from of either, but one is better than the other. If you send the OD of the ring and the tooth count, the ebay seller should be able to get you the right tool.

I’d just source a whole new belt ring


Is the freewheel pawl where the ratchet ring is? That is what the problem I am having with my kickr2 and is causing me grief. My ring broke in 2 and I can’t remove it. I don’t have the correct tool to remove it and can’t find it.

Thinking about just selling the parts or for parts on ebay.


I have a 2017 kickr and the bearing behind the ratchet ring have failed after over 11,000 miles! Contacted Wahoo to enquire about a tool to remove the ring or even the maker of the ring so I can idenfiy a tool on the internet but after a few emails back and forth they refuse to discuss this any longer! Very poor customer service :frowning: The ring is quite unusual and despite endless searches on the internet I’ve so far been unable to source a suitable removal tool! I have even designed one and had a quote to get it made using specialists CNC machining and then hardening and it’s quite expensive (over £300) It’s very disappointing that Wahoo will not give the purchasers and users of their equipment the support that they ask for, many of us are quite capable of repairing things and with the tool or even knowledge of the maker of the ring from wahoo this frustration and annoyance could easily be avoided! My search continues and should I find a solution I’ll post it here! Good luck!

I’d take it to Facebook and Instagram. Tacx had the same problem with the Neo and eventually Garmin was shamed into a replacement housing that contains the bearings.

Hey folks, sorry to revive an old thread. I 3d printed a tool that works on the first gen KICKR, not sure if it’d work on others but it’s easy to tweak the design. It’s very difficult to remove, but I’ve had good luck removing the flywheel & plastic discs, then screwing the flywheel to a workbench while using a 2’ breaker bar & the tool.

Hello, can you make one that will work on the gen2 ratchetring?


I don’t have one to measure but it’s worth trying the first gen tool on since it just costs a few dollars in filament

How can I contact you to do this purchase… I would like to attempt this fix due to nothing else being wrong with this trainer…



Hey Leurch, I’m happy to print & ship one to you, but it might be easiest to have someone local with a 3D printer make one for you. I’ve shared the design here so anyone can download & print it: Wahoo KICKR 2014 Drive Ring Removal Tool by Kgreimel - Thingiverse

Awesome work!

I am curious though, you can remove the ring with a plastic tool? I once removed a ring from a DT hub and it was quite the effort!
