Summary

The Trek 820 is known to handle the streets better than some of the higher numbered Trek's (i.e. Trek 3700). The Trek 820 is different than the rest because it is Trek's generic bike so almost any tire or seat will work due to the interface of the Trek 820 being up to the industry standard.
