Don't forget your snacks.

You'll barely notice Timbuk2's Bicycle Seat Pack loyally hanging from your saddle until you find yourself on the shoulder of a road somewhere in need of its contents, which could include any combination of tire levers, spare tubes, and snacks. Timbuk2 designed the bag with an outer loop, perfect for holding onto a light to keep you visible on dark rides, and an internal key fob to make sure your house key doesn't come tumbling out when you're digging around for that last gel you know you threw in before you left. The pack attaches easily to your saddle with adjustable buckles, and is constructed with durable Cordura ripstop nylon to make sure it's up to the job of carrying the essentials you can't ride without.

Good Quality Saddle Bag

  • Familiarity: I've used it several times

I bought both a large and a medium bag to see which one I liked more. After testing each size, I decided to keep the medium bag. This size will fit: 1 tube, 1 C02, 2 levers, and a small patch kit (with very little room to spare).


-High quality craftsmanship

-Stable and secure attachment

-Easy to attach and remove from saddle


-Some side to side motion, but not noticeable

-Straps hang down on the sides*

*Pro Tip: Use small rubber bands to keep the straps up

Pretty good.

  • Familiarity: I've put it through the wringer

Perfect size, has a key holder inside and enough space for energy bars, Id and cards, only missing a strap to tie it to the seat vertically.

Perfect for a dropper seat post

    If you're like me and don't like to wear a pack unless absolutely necessary when you are on your bike, this is what you want. Plenty of room for my multi tool, CO2 cartridges, extra tube, and tire levers in here. The best part about it is that it doesn't attach to the actual seat post so when you drop down you don't have to worry about smashing the velcro strap. Good amount of adjustability here. Doesn't hit the rear tire of my Pivot 429 when the dropper is all the way down. I have about 1.5 inches of seat tube exposed from the frame before the dropper post comes into play.

    If you have any questions, hit me up.

    Which size bag did you get to fit those tools in it?

    Hi Keith,

    I picked up the Large size for my bike. I can fit one tube (29er), 2 tire levers, multi-tool, patch kit, and CO2 cartridge and nozzle in there. It is a tight fit but it all goes in there.
