Why 80% of riders regret sticking with cable brakes — and how NUTT hydraulic changes everything.
Quick answers to the most common questions about NUTT hydraulic brake systems.
The NUTT A1 is constructed from high-strength aluminum alloy, making it significantly lighter than comparable cast-iron brakes. While the exact weight isn't listed, the focus on a lightweight design makes it a great choice for riders looking to shed weight for better performance, especially on e-bikes and mountain bikes.
Yes, the A1 is universally designed and compatible with both 160mm and 180mm rotors. This gives you the flexibility to use your preferred rotor size or match the one currently on your bike. Please check if your frame can accommodate the larger rotor.
Yes. The A1's hydraulic system is designed to provide a powerful and sensitive braking feel with a very light lever squeeze. This reduces hand fatigue on long rides, making it a comfortable and effective option for various cycling disciplines.
Yes, like most of our premium NUTT hydraulic brakes, the A1 comes pre-bled with mineral oil. This means you can install it right out of the box with minimal fuss. However, depending on your hose routing, you may need to trim the hose and re-bleed it for a perfect fit.
An aluminum alloy body, like that on the A1, offers vastly superior strength and durability compared to plastic. It won't deform under high braking forces or heat, ensuring consistent piston movement and a longer lifespan. It's also more resistant to damage from impacts or crashes.
