I'm enjoying this little hybrid as much as any bike I've ever owned (Giant Escape 1) so I dropped some bucks on it this weekend.
It sees very little dirt and I want to explore more of the city on it so I'm dropping the OEM tires (32c and 60psi) for a set of Panaracer T-Serv 28c at 105psi. Roll resistance is the only set back I see in the Escape. I'm going to see if I can step it up a bit. Wish me luck. The upgrade costs about 25% of the purchase price of the bike.
Also bought a 2W Planet Bike blaze headlight for it yesterday
