Building a Flat Kit

Building a Flat Kit

A flat kit is all those emergency tools or parts that you need if you get a flat, but also if by chance you break a chain or something like that.  We call it a flat kit but think of it as an emergency kit.

Seat Bag

Staple items that go with me on every ride :

  • Tube
  • Tire Levers
  • Inflation Device
  • Small Multi Tool

Getting into specifics –

Racing – (These items are normally in a seat bag or wrapped around my stem.)

Explained – I use CO2 on the side of a trail when racing for weight and time. The Park MT-1 disappears into a jersey pocket but has enough leverage to adjust your seatpost or stem. Pedro’s tire levers are awesome and they have a life time warranty. Break it? Send it to them and they’ll replace it. The $1 bill is to boot a tire if there is a tear.
Longer rides with a Camelbak –

Explained – For longer rides I like to pack a little more. A handpump is for multiple flats or a slow leak. The Bontrager Rollbar has just enough uses without being bulky. Two tubes in case someone has to borrow one from you. Patch kit is for more than 2 flats.  $5 bill is for either food, or in case you need a ride home it is normally enough down payment for a taxi until you can get home and get other money. I also have used the bills to boot a tire in case of a large tear in the rubber.

For awhile I had little flat kits made all over the house. Just in case I decide to hop on the cross bike or didn’t want to deal with a bag. Everything rolled up and stuck in a snack size zip lock bag.

Healthy hints

Make a photo copy of your drivers license and a credit card.  Write down your husband or mothers cell phone number and put one of these in each seat pack.  If anything happens to you it has your information but also it can get you out of a pinch with the credit card number.

    Thanks for the info, I was wondering what “boot” means as in “The $1 bill is to boot a tire if there is a tear”.

      A boot is a temporary repair where you use the $ bill to put in between the tube and tire where there is a rip in the tire. This makes it so the tube doesn’t get through the hole on the tire.

    Great info! Especially the photo copies. I need to get my butt in to your store and let you watch me try to change a flat. I watched the video on UT and it was pretty informative (at least Kelly now knows how to change a flat), but I would probably freak out and have a panic attack if it really happened to me.

    Good post. I never thought of photocopying the driver’s license and credit card, I always bring the real things and am slightly paranoid about losing them. Good tip!
