My concern about how much is too much grease, come with the 54+ tooth and more with third party suppliers. The fact is that a thicker film of grease between the two ratchets can avoid them to be fully engaged together that leads to a major failure, definitely roundind the edges of our precious ratchet. Yes, its a ring, after all... As long as I appreciate the noise of the hub that is pretty convenient to prevent pedestrians that something is coming from their back (lol) I have tested simple oil whithout any issue and as you mention, préventive maintainance is so easy to do that you can keep an eye on how things are going inside. I only use grease to be sure to guaranty the best sealing against mud or dust just between parts that are not so waterproof. Be aware that vicosity of thick grease especialy under cold conditions are prompt to gelify. For experimentation, I have also tryed WD40, product that I dont recommend at all but for other reason. The point is that, as long as you keep the all thing clean, you're good to go. My guess is that the cleaning is more important than the lub. If you end up with a grain of salt in your 60 tooth ratchet, the height of the engagement will surely be compromise ! Keep a paire of 17 tooth in your pocket, just in case...
I've only used the DT Swiss grease based on the DT Swiss recommendation. Though it is the same as the dumonde. I've been running the 54 tooth ratchets since DT Swiss released them and love them to this day. They really hit it out of the ballpark with it, which I honestly can't say about i9 or other hubs. I have/had them on multiple bikes with tens of thousands of miles combined. They've been bulletproof in all weather conditions, from the 90s down to the -20s with the fatty. For years, I've put extra grease in them, but not to the point where they're jam packed. To this day, I haven't had an issue.. But, as you mentioned, I do regularly maintain them. I'm so in tune with the 54 ratchet that I can tell by the sound alone when they need service. If only I was that in tune with my girlfriend 😁
I sent an email to ask. Too much is almost impossible ,this special grease is expensive, also the Swiss design has clearance to support the grease. But less grease only results in less dust hindering capability. In addition, the greater the noise, the greater the wear (simple energy conservation theorem, and the sound comes from vibration)
I do it based of sound. I'm so used to the 54 tooth ratchets that I can literally hear when they need the grease refreshed. The hub gets significantly louder when the grease gets broken down over time. Considering how small the teeth are on the 54 tooth ratchets and how easy they are to service, I would do it often. On my 29er, which I ride the most, I refresh the grease minimum 2 times a season, sometimes 3. I'd say that equals out to about every 50 - 70 hours. It's easy, cheap and keeps the hub quite and protected. 👍
Thanks for doing this video. I have the DT Swiss 350 hub and now I know how to do some simple preventive maintenance. I especially appreciate the comments on the amount of grease - I built my bike and had a nagging concern that I used too much. Do you a recommended grease?
I've experimented over the years and never came across an issue with to much grease. Not to say I've ever completely packed the hub (now that I think about it, it would be interesting to see what would happen if I tried that) but I've come to the conclusion that "reasonably" more is way better than less. As for greases, I've only used the DT swiss and Dumonde tech, which I believe are identical.
hi. i just got a new one and the cassette is engaging when in freewheel. if i pedal backwards it start to engage the cassette instead of freewheel, which it does if i hold the wheel. do you know if this is "normal" on new hub or could be an issue? thanks
Apologies' for the delayed response. if I'm understanding this correctly, this is definitely not normal. No matter how the ratchets are placed, they should always engage when pressure is applying when pedaling. once peddling stop, they should freewheel, reverse pedaling should freewheel as well. I would have the hub checked and/or replaced
Dumonte TEch pro x is the same grease. you can use slick honey or slickoleum but it won't won't last as long and the ratchets will be louder. I would buy either the dt swiss or dumonte tech pro x. Either bottle will last a very long time.
Either one of the products in the links below will work. I'd look around for the with the best price. no matter which one you buy, it'll last you a while. let me know if you have any other questions DT Swiss hub Grease www.universalcycles.com/shopping/product_details.php?id=7784&attribute=263681 Dumonde hub grease www.amazon.com/Dumonde-Tech-Pro-X-Freehub-Grease/dp/B01N4WWH4B/ref=asc_df_B01N4WWH4B/?tag=hyprod-20&linkCode=df0&hvadid=309849426425&hvpos=&hvnetw=g&hvrand=8507966520746489615&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9016979&hvtargid=pla-569946966448&psc=1

The 370 hub are the same inside.
pretty much all DT swiss ratchet hubs are very similar inside. love DT hubs 👍
You may have mentioned this in the video, sorry in advance if you do! For the 54 teeth ratchets whats the service interval roughly?

@@zoubtube thanks for that. That’s not that bad

Are the two ratchets identical?
Yup! As are the springs.
Congratulation for video. Can you recomendation a alternative grease?
