One of the best instructional videos I have seen. Outstanding work. Thanks very much. 👍

[WowRixter]

I love my 240EXPs, and no need for a bell on my bike 😉 Another fantastic video Tobias! Thank you

[indusrtial]

bro is singlehandedly the best PR machine for DT Swiss without commission

[gearmonger]

Again, the most logical presentation of irrational content that I love.

[cmarnold]

Thanks, I just about crapped myself changing my cassette when the whole thing came right off!

i upgraded from 36 to 54T and initially the ratchet sound was very quiet (but not ALL the time, just suddenly it lost almost all sound lol.) i removed the grease from one ratchet and left the other one with a LITTLE lube, that made the sound way louder.
its not THAT big of a difference to upgrade from 36T to 54T but its definately worth it imo. its 9° less crankmovement required for a click! :) 54T is especially AWESOME for technical climbing

So nice to see somebody else using my favourite Scott shop towels!

Super clear and neat, not to mention super quality! Thanks a lot for clear steps, as well as all the extra details!

Wonderful. I was feeling like a dinosaur with my longing for the simple cup & bearings of 1960s and 1970s before sealed bearings. I'd do them twice a year even though it wasn't absolutely necessary

[MegaRobboz]

woo new rides of japan. Turn up the volume, full screen and normal speed. Noice

Gem of a video however I found these adjustments helpful:
1. I couldn’t get the non-drive side bearing out using the hammer so I switched focus to the drive side.
2. I used the dtswiss lock ring tool with the axel still in place. This helped make the torquing motion super secure. I used a visegrip wrench to really lock onto the lock ring tool and a 2ft pipe extension on the wrench. The lock ring broke loose immediately after never being loosened for six years.
3. Bearings were still very stuck so I used a pick to peel away the seals and move the balls to one side. This reduced the strength of the bearing and helped free it with a gentle hammer blow to non-drive side then drive side.


DTSwiss brand lock ring tool is a good investment at $80.

eBay sellutions hub bearing shapes were a good investment at $25. Tool was not perfect but very helpful.

Very good video, thank you! Also solved my issue to go for the 350 or 240 because now I saw the internal construction

Recently bought this hub, I am happy I bumped in to your video :D This will help me keep out from abusive bike mechanics (not all of course) changing the parts of the actual hub.

[brandonamos]

This is a great video which a number of months ago helped me change my ratchets.

I now have an issue which I think it bearing related and your video gave me the confidence to hammer out the non drive side bearing.

One bit of advice I would add is getting a larger adjustable spanner. I bought an 18” one and this made unscrewing the ratchet and also removing the brake disc very easy as leverage meant I didn’t have to put much effort into it.

Perfect !!!. Thank you. New DT Swiss wheels/hubs are in the garage, awaiting a new tubeless valve stem. I bought them for the ease of replacing the bearings, as you've shown. Glad to see I wont need to buy a bearing press :-)

[willarnot]

Well done amigo. Great info & demo. Exactly what I was after. Cheers

[moxerl]

It's a no-brainer to buy once there is a maintenance video by RoJ! Recently received my 240 EXP wheelset by LIghtBicycle and love it so far. Thanks for the great content, as always.

[dancumberland]

Man what a great tutorial video!! Even includes the fuck ups we all make. I love this guy.

[stijndeklerk]

I never managed to get that bearing underneath the ratchet. Now I know. Thx.

[clarkritchie]

Awesome video, thanks for the tutorial! 🔧
