Gravel bike go Brrrrrrrrr!
As said, SO easy to install. Makes you feel at least 30% faster, and 70% cooler. Let's be honest, that's why you're buying it.

Angry swarm of bees following you when you ride.
Easy to install. Search YouTube for process. Do not over grease the ratchets, just a thorough thin coating will do.This changes the engagement of the ratchet making climbing a lot smoother.It is quite expensive for what you get.

Instant Power Transfer, Transformed Rides (Plus Super Easy Install!)
This DT Swiss 54-tooth upgrade kit is a game-changer! The moment you install it (which is incredibly easy), you'll feel the difference. Engagement is lightning-fast – the slightest pedal input translates directly into forward momentum. No more lag, no more wasted energy. Technical climbs become a breeze, and powering out of corners feels incredibly snappy. If you want a more responsive and exhilarating ride, this upgrade is an absolute must-have.

A needed upgrade, just expensive
This is an expensive upgrade to the 18t ratchet that comes standard with most DTSwiss OEM wheels. The 18t is probably fine for road applications, but for gravel and MTB, the 54t is much better. The ratchets are genuine DTSwiss, and came with the special red grease and the springs needed to upgrade from the 18t. It’s easy to pry the old hub off (in my case, a Shimano 11 speed hub) to get to the internals to swap out. You only need a little grease on the ratchets and springs, it doesn’t need to be coated excessively. Once installed, the 54t sounds like music to your ears. It offers super quiet, super quick engagement that is perfect for gravel bikes. This is my 3rd set of DTSwiss wheels to upgrade to 54t, and it is one that works and lasts. I have almost 7k miles on my hardtail, and outside of yearly maintenance to re-grease the ratchets, I’ve never had a problem. The only reason for 4 stars is the price.

Easy, impactful change to your bike
Not an inexpensive change, but definitely an easy one (takes just minutes from starts to finish) and you can feel and hear the difference afterward!
