Necessary Items for a Flat Kit
December 12th, 2007 by Arleigh JenkinsThis past weekend I was honored to help my friend pick out some essentials to throw in a seat bag for his mountain bike. Here are my suggestions and why :
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.)
- CO2 Mini Air Chuck
- 2 CO2 12g Cartridges
- Park MT-1
- Pedro’s Tire Lever
- Tube
- $1 Bill
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 -
- Handpump
- Bontrager Rollbar
- Pedro’s Tire Levers (2)
- Tubes (2)
- Patch kit
- $5 Bill
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.
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 in a tube and stuck in a snack size zip lock bag.

Any specific reason you go with 12g Cartridges as opposed to Big Air? (when racing)
Thanks for the list.
Why the 5-dollar bill for the longer ride? I must be missing something.
I’m normally running my 29er tires at 25-28 lbs which a 12g fill it up to. Most the local shops don’t carry the Big Air refill so the kit is great but getting refills was a pain!
Ben -
You didn’t miss anything. I forgot to add in that I carry a $5 incase I need food or a ride home. Normally $5 will get you a gatorade and a couple snack bars, if you need to it is normally enough to convince someone to drive you 10-15 miles home.
Thank you Arleigh.
I carry a 2 tube, 1 lever(yellow fat pedros), CO2(innoflation? nozzle, 2 tanks),
16g tanks, 12g is never enough, I have never blown 2 at once and find the Big air leaks out before I flat again.
Do any of you guys have a hand pump preference? That is something I am working on for another post.
Being poor, I always carry a hand pump. I’ve a free co2 inflater that I got for free for joining NORBA back in the day, but I don’t like the idea of shelling out cash every time I flat. I normally carry 1 tube, hand pump, park mt-1, chain tool and tire levers, gerber multi-plier, and an avenir multitool. That’s prolly a lot of stuff, but it’s stuff that I have with me at work and tooling around town, so I like to stay versatile.
Helium would be lighter and preserves rubber better. (Leaks back out faster, though.)
I don’t have a hand pump or a flat kit yet. I guess I’ve been lucky so far, but I need to invest in them before my luck runs out.
I’ve been using a Topeak Turbo Morph for a long time. It’s the best hand pump I’ve used, and I seem to use it at least once a week. Also Topeak is an amazing company to deal with if their stuff ever goes bad. Always a plus. I prefer hand pumps to Co2 since I flat so often.
