I think it’s great but could be better if it were a little larger. Today’s tire sizes require very large tubes, which barely fit in this. But I still think it’s pretty great as it is.

Great product

I have two of these things. Use them for holding bear spray (there's a lot of bears in AK). This design checks all the boxes for bear spray: holds the spray tight; not too tight that you can't get quick release; close access for quick draw; isn't in the way (I don't notice it is there); works with dropper. HInt: keep the polyester sleeve on the bear spray, it will still hold tight. I've tested this summer on over 500 miles of hard trail, and it works perfectly. However, I haven't had to pull it yet in action.

Perfect fit

I did not realize that it did not come with the tube or the CO2 cartridge or valve

Got tyre buzz on my Kenevo SL (S3 with 180mm dropper), but ideal on shorter travel bikes and hardtails

Awesome product if you have SWAT compatible saddle from Specialized

A fantastic solution to take the camera wheel on the rides. Free pockets and no stains. All packed to repair, in safe and adjusted place.

THe best

I added this to my Epic Evo to hold my spare tube, tire lever, and a CO2. Works really good. Nice and snug under the seat.

I swear by this, best storage solution for going fast!

Compact little unit that holds spare tube, CO2, tire lever very well. Minimalist, no frills. Works with dropper seat post. Highly recommended.

Paired this with the zee cage w/tool and I never have to put a pack or anything in a pocket again

I use this to strap my phone to my saddle, keeps things minimal. I don't need to wear a jersey if I want to go for a quick ride. Works well and enables me to do laps around the park with my bluetooth headphones on and my phone is securely strapped to the saddle.

My 22 Stumpy Evo has SWAT internal storage, which is great, especially with the water bladder. However, a normal spare tube takes up a lot of space. Having the tube and a cartridge strapped under the saddle, is a good solution. My CO2 head won't quite fit as it has a builtin gauge. Now, I can put way more stuff in the frame including a tubeless plug kit, more tire levers, another C02 cartridge, CO2 head, chain tool, a few first aid items and lots of food. Most importantly, I don't need a pack or to keep anything in my pockets.

Love this product. Was suspicious at first but it holds it all in nice and tight.

Does exactly as advertised! Everything is very secure and after many long miles nothing has fallen out.

Was able to store everything as expected and described. I've been on multiple rides and everthing stayed in place. Not sure why others experienced problems.

Fits everything I need to ensure I am not stranded out on a ride with a flat tire. This fits neatly and securely under the seat.

Everything fits nicely in this but it comes open easily. I've been using it on a Epic Hardtail and pretty much on any downhill something will fall out. I think they just need to beef up the attachments on the next model and it could work nicely.

Much nicer than strapping a tube on the olds school way. No more scratched frames!
