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.

So. Much. Engagement!

Grabbed a 54t for my 240s, and love how they feel now. Makes technical climbs a breeze, as the power to your wheel becomes almost instantaneous. Quieter than an I9 hub, but definitely louder than the other options!

54 tooth "Upgrade"...?

  • Familiarity: I've used it several times

Well, the swap was easy, but as always with a DT 240, ...where does all the water come from?? Anyhow, after getting all the water and grit out of the freehub and hub shell, the old 18 tooth ratchets were in perfect shape, so i just threw them in the toolbox and put in the new 54s. Well, first, it is tough to really grease something with SOOO many little corners, and points. So, I went as light as possible with the DT grease, but felt like it was tricky to get all of it without over-greasing. Well, I put it back together, and it is pretty awesome. I was a little scared of it being "draggy" but I cannot feel a difference. Also, it is not incredibly-annoyingly-loud and abnoxious like I9(Awefully annoying) or CK(less annoying) hubs. It does make the 240 louder, but not much. It is slightly louder, but with a super high frequency "Buzz." If you want silent, stick with the 18 tooth. If you want wicked engagement, get the 54 tooth. Its that simple. I love the engagement, and will grease it constantly to keep the noise down. Good upgrade...As long as the EXTREMELY TINY teeth hold up!!!
