DT Swiss Upgrade Kit 240S 54T SL

Makes a big difference compared to the standard 16t Very easy to fit

Pros & Cons

Switched from an 18T ratchet to this 54T. The better engagement is definitely noticeable and a lot more pleasant than 18T. The sound is very loud, definitely bold but sometimes a tad irritating.

Pros & Cons

Easy upgrade for faster engagement when pedalling and navigating technical terrain. Much louder buzz when freewheeling gets peoples attention.

Pros & Cons

Pricey, but worth of an upgrade, the sound is pure joy. Great engagement. Fast delivery to the UK, no extra import fees.

Pros & Cons

good product , picks up well easy to fit.....makes a lot of noise....a little too much for me I took it out again and went back to my original gears

Pros & Cons

Big difference from the original. Definitely buying mode if you have fewer intervention points now. Should be standard you might think ...

Fast delivery on a quality product

Pros & Cons

These pulleys have been my dream for years, now I got them, the delivery was very short, even though the pulleys are sold out everywhere else! Mounting the pulleys couldn't be easier, and the sound is simply a dream. By the way, you can adjust the volume very easily via the amount of special grease, from whisper-quiet to really loud, simply brilliant!

Pros & Cons

Meets expectations

Pros & Cons

I replaced the original 36-tooth kit with this 54-tooth kit. The sound has improved, now more audible, and the response of the pedals and the vacuum as soon as you start pedalling again has also improved, although the change is not as marked. I have some doubts about the durability of the kit.

Pros & Cons

Goods as described, fast delivery.. Recommended ++

It does what it’s supposed to do, great upgrade from the standard 18t ratchet, shame the cost is so high for two small aluminium rings, two springs and a tube of grease. Great service from Mantel and delivered safely to the UK.

Pros & Cons

It's as easy as pie to fit this kit to replace the 18-tooth mm kit that came with the original wheel on my bike. The improvement in pedalling efficiency was immediately noticeable. The louder noise of the freewheel compared to the 18-tooth is not as annoying as I had imagined.

Pros & Cons

Makes an immediate difference

Pros & Cons

An upgrade that improved the engagement feeling, it feels quicker and more premium

Pros & Cons

Works top . Nice sound . And no more play at crank engagement .

Pros & Cons

First purchase on Mantel! Very satisfied because the price is great and the shipping service equally great. Material arrived well packaged and on time.

Pros & Cons

This is one if those small upgrades that makes a big difference but is often over looked. It's one if those components that most riders never think about, just hear as they coast down a trail as it buzzes away. But it's an important part and depending on your riding style can make a big difference. Most noticable is how quickly the rachet engages delivering power to the rear wheel particularly on trails with sections that need the the odd pedal stoke here and there. The quicker engagement also makes pedal strikes more predictable when climbing technical rocky ascents and therefore easier to avoid them as there is less turn of the crank before power it delivered. My recent trip to the Peak District really highlighted this as valuable upgrade and I very pleased. I mostly maintain my own bike and all the components on it so I'm probably someone that notices the slightest difference with the smallest adjustment but I would say this particular upgrade is something most riders would benefit from even if they didn't notice it.

Pros & Cons

Difference. No more noticeable backlash, instant engagement. Recommended.

Pros & Cons

The improvement over the standard bushing is very noticeable, it engages much faster. It is very, very easy to fit and also sounds better.

Pros & Cons

Makes technical climbing much easier but for 2 small pieces of aluminium, it's far too expensive. Not only that, but when putting down high torque, it tends to skip.

I went from 18T to 54T and the difference is like night and day. Highly recommended!!!
