Published on November 19th 2023


Today we`re attempting to answer the age-old question "Is bigger better?" Brakes are the most important part of your mountain bike when it comes to safety. The sooner you can stop, the less likely you are to fall off the edge of a mountain. So Anna Cipullo felt she needed to test which brake size offers the best braking performance. She tested the feel, stopping distance and heat dissipation of each size rotor to see which size outperforms the others in all of these aspects. ⏱️ Timestamps ⏱️ 00:00 - Intro 02:09 - 180mm Disc 05:36 - 203mm Disc 09:33 - 220mm Disc 13:57 - Times & Conclusions Useful Links: πŸ› NEW MTB Bike Maintenance Book πŸ‘‰ Submit Top Mods, Bike Caves, Rewinds and more to us πŸ‘‰ Racing Highlights & More On GMBN Racing πŸ‘‰ Watch #shorts on GMBN πŸ‘‰ Sign-up to our newsletter πŸ‘‰ What size brake discs do you have on your MTB?
