We at Bike Bakersfield believe everyone should know how to change a flat. Flats happen and you should always be prepared. Carry an extra tube, a pump or c02, a tire lever and for those of us who have bolt on hubs make sure you have the appropriate wrench to get your wheel off. If you do not know how to change a flat please feel free to stop by the Bike Kitchen Tues, Weds, Thurs and Sat between 10am and 2pm or on Fridays from 1pm-5pm and ask me how. I will be more than happy to teach you!
