The best gets better.

If you're looking for quicker engagement on your pedal stroke, DT Swiss offers a Star Ratchet Upgrade Kit to make its stock 18t hubs more responsive. The kit comes with a set of two of DT's signature ratchet rings, along with a pot of the grease that the manufacturer recommends for installation. Upgrade a set of 190 ceramic, 240, 350, or 440 freeride hubs with the kit to take advantage of quicker engagement for covering attacks on the road or popping across obstacles on the trail.

Will these work on DT Swiss 370 Hubs that come on the 1900 spline wheel set?

Charlie - can't confirm 100%, but you may want to pull your rear wheel off and then gently pry the cassette away the from hub. This will tell you if you have the pawl (3 prongs) or the ratchet. If you have the pawl, which I believe you do in a a 370, you will need more than just the above kit.

Clifton M what else would I need in top of the kit?

Charlie and Leo: I have these exact rims and found this video that explains it perfectly:

I've priced out the conversion and with the tools you're looking at $250+ to do the conversion and many of the removal tools you will need to do your wheel hub bearing replacement anyway. So having the tools might be nice, with that said I'm going to check with my LBS to see how much they'd charge to do the conversion. hope that helps.

How's durability and maintenance on 54T vs 36T? I heard maintenance goes up as teeth go up. True?

Hey Josh,

Thanks for the question. The maintenance is the same as standard maintenance which is little to none and easy. My co-worker has had the 54T star ratchet kit installed in his rear hubs and hasn't had any issues for over a year and a half and I have haven't heard of any longevity issues.


DT Swiss 54 T star ratchet upgrade

  • Familiarity: I've put it through the wringer

awesome and well worth upgrade. engagement is instantanous...specially on chunky uphill climb


  • Familiarity: I've used it several times

Almost no slack and instant gratification when pedaling in the technical rock gardens of Colorado.

Thank you so much for the great review Kris. I'm super stoked you love the new gear!

get it if you have dt swiss hubs

  • Familiarity: I've used it several times

great upgrade to a great hub that had below par engagement. I added to dt swiss 240 hubs on a road and mtb and don't know why I didn't years ago.

More Power

  • Familiarity: I gave it as a gift but have feedback to share

Upgraded after trying the stock ratchet on the dt swiss 350, made the hub almost as good as my i9 hub. Highly recommend to upgrade if you do technical climbs and want instant power to the wheel. The noise level after the upgrade is more noticeable, hikers seem to hear me coming without using my bell as often. I will always make this upgrade to any dt swiss hub that I own.

Get the engagement!

  • Familiarity: I've used it several times

Ever wonder ... "how long do I have to pedal for my hubs to engage?".... well if you upgrade with this kit you won't have time to wonder that anymore!

Upgrade your ratchets!

Faster Engagement

    This kit does exactly what it's meant to. Pushes you up to near instant engagement on your rear hub. I got this for a change over to single speed and I'm glad I did.

    54t Upgrade is Awesome

    • Familiarity: I've put it through the wringer

    Upgraded from the 18t version. It was super simple and I love the way DT hubs are easy to service. Took maybe 5 minutes. The engagement is really fast and of course it also sounds awesome.

    Gotta Have

      Swapped these out on my Enves for both my Blur 3 and Hightower. Really nice to have some extra engagement out on the trail.

      So Much Engagement!

      • Familiarity: I've put it through the wringer

      You don't know what your missing until you try out a hub with high engagement. It is so worth it. This guy is easy to install, bomb proof, and pretty noisy. Highly recommended if you have DT wheels with the other star ratchets

      Check what you have before ordering.

      • Familiarity: I've put it through the wringer

      Didn't have engagement issues with my 5010 but though the 36t upgrade may be worthwhile. Got the existing ratchet rings off and low and behold the 5010 already had 36t installed instead of 18t rings. As for how much better the 36t is over the 18t I can't say. I can say 36t engagement is really good. Guess I already have a replacement set if ever needed. Lastly, installation is a breeze, clean you drivetrain then go watch a video on you-tube on how to do it. You can do the job without tools in 15 minutes.

      Easy and Makes a Difference

      • Familiarity: I've put it through the wringer

      I swapped an 18T on my Yeti SB5,5 for a 54T and am mega happy with the faster engagement.

      This is super easy to install. No tools required if you have a quick release axle.

      Just make sure to go easy on the grease. Too much grease is a bad thing. And with the finer teeth on the 54T, too much grease can cause the teeth to wear out faster.

      For applying grease, try finding a small/fine paint brush to get an even coating of it in the hard to get to parts.

      highly recommend it!

      • Familiarity: I've put it through the wringer

      if you are struggling to ride over technical terrain because you have too much play in your pedal stroke... Buy the upgrade. its something that takes two mins to install and will make life much easier.

      Upgraded Response

      • Familiarity: I've put it through the wringer

      If you ride a DT Swiss hub, I would recommend purchasing this upgrade kit for better freehub engagement. It will really help for a better riding experience through the techy stuff.

      Easy Upgrade

      • Familiarity: I've put it through the wringer

      Really easy to install and increases your pedaling engagement. It's very evident once you install it but you really feel the benefits it on uneven rocky climbing sections. Much easier to just but this part than upgrade an entire hub.

      Must Have

      • Familiarity: I've put it through the wringer

      A very quick and easy upgrade for much quicker engagement. No brainer upgrade.

      Go for it!

      • Familiarity: I've used it several times

      This upgrade kit is awesome you can definitely feel the difference in the hud. And much cheaper than buying a new one.

      Easy upgrade that is well worth it.

      • Familiarity: I've put it through the wringer

      This is an easy, affordable upgrade that is well worth it. The upgrade to 54T makes the engagement a lot quicker and makes climbing a lot more sure. Stop thinking about it and do it!

      Easy Upgrade

      • Familiarity: I've put it through the wringer

      DT Swiss makes it really easy to improve freehub engagement with this kit. It only takes a few minutes to install, and the quicker engagement will improve your riding experience.
