«It is so responsive it doesn't feel too different to a deep rim and of course it is the fastest there is.»

«All you hear is your breath and the satisfying sound of whoosh-whoosh. It gives you a sense of being one with the road. Especially in Ironman racing where you are set back from your competitor and all you hear is your breath and the satisfying woosh-woosh-woosh of the disc. It allows you to settle in, to feel how smooth your equipment is and also push to your maximum ability to the end of the bike split!»

«For me, the disc was and is THE sign of a real time trial and gave me the pure, mental motivation to pedal full speed. It was the last bit of difference in material to complete a perfect time trial.»

«The nature of the bike course is important when it comes to choice of setup. What’s great about the quality and weight of the new ARC 1100 DICUT DISC is that I now only have to change the front wheel. The disc is light enough for hilly courses and fast in all conditions. At the same time I can run a tubeless setup with wider tires which is both the fastest and most comfortable solution.»


«With the growing popularity of high-volume tyres, both for ride quality and potential rolling resistance gains, DT Swiss has shaped the ARC 1100 DICUT DISC with an internal rim width of 20mm. Recommended tyre width is rated between 25-32mm, making it easier to mix and match with contemporary options from the best road bike tyres.»

«On paper, it ticks just about all of the boxes I’d look for, if I had to choose one disc-brake-disc. I like the 20mm internal rim width, the lack of tire restrictions, the weight, the brake compatibility (Center Lock), and DT’s typically very high build quality. If that’s what you’re looking for, I think it would be hard to find something better.»
