The Susan G Komen hybrid bicycle is the perfect blend of road bike and comfort bike. It begins with a sturdy steel frame. When you re riding to the store out for a training ride or just making a coffee run you can count on a reliable 21-speed drivetrain with a rear derailleur from industry leader Shimano to tame the hills and get you moving. If you get moving too much you can rely on front and rear alloy linear pull hand brakes to keep your speed in check. Ideal for adult females.
