There is a good reason Trek has been producing the 520 for more than 30 years. It was and still is one of the most touring specific designed bikes on the market with a more comfortable upright riding position, low bottom bracket and rack mounts to improve balance, and a wide range of gears. Additionally, there’s Shimano components including Deore and Deore LX derailleurs give it reliable shifting performance. However, the bike lacks some features that can be found on other bikes at a comparable price like disc brakes, extra water bottle and pump mounts, and included fenders. Regardless, the 520 is a comfortable and reliable touring bike that is ready to go for a long ride the day it is taken out of the box.
