The Civante has a nice upgrade from the other Yamaha bikes. The Civante has the disk brake rotors (SM-RT70) used by the Shimano 105 7000 series with ICE TECHNOLOGIES to "significantly reduce heat build-up in the brake system to ensure consistent high performance braking even on the steepest downhill stretches". These 105 disc brakes are ebike rated by Shimano. This was a nice surprise =) Compared to the Urban Rush, the Civante uses the updated Tiagra 2019 calipers (BR-4770) while the Urban Rush uses the older calipers (BR-405). The newer BR-4770 calipers use the same brake hose kit as the Dura Ace calipers. Additionally, the Civantes’ hydraulic levers use the same cable pull ratios as the current 11-speed group sets. This means we can “unofficially” use the Dura Ace (R9120) and Ultegra (R8020) derailleurs with our 4720 Tiagra shifters when it’s time to upgrade.
