The apparently humble Hope Universal Disc, while super simple is actually one of the best mountain bike disc rotors you can buy. Laser cut from a 2.3mm thick sheet of custom steel, the wider diameter helps to handle high temperatures, resist warping and increases lifespan.
Available in a wide range of sizes, it's compatible with all Hope brakes (and most others) and best of all, the Universal Disc is not even expensive.
FAQ
Can I use one of these with my existing brake system?
Probably! Most brakes will see a performance benefit from moving to a wider 2.3mm disc, with pads engaging earlier and less dead stroke at the lever. You’ll get a more solid lever feel, better rotor life and improved heat management compared to thinner options.
What size rotor should I pick?
It depends on what you want. Bigger rotors add noticeable power and cooling to your brake and Hope manufactures a mount for almost every size combination, so if you are pairing this rotor with one of their brakes, you are free to choose any disc size you like. If you are overheating or struggling for power with your current brakes, then go bigger. If you’re looking to take the edge off a powerful brake or save weight then smaller. We’re always happy to try and advise in the shop so give us a call if you’re not sure.
How extra much do bigger rotors weigh?
Not a whole lot. 180mm is 140g, 200mm is 172g and 220 is 210g. Pick by power and heat rather than weight.
