Should be engineered to store 2 pry bars and a wider inner tube than the 25s. Also encroaches on water bottle storage. I returned mine, could have been engineered much better for the diverge. Also the valve extender sort of rattles around, requiring careful placement. Also a single 16g CO2 is insufficient, if just one, at least make it a 25, adding a control to the CO2 valve would also be a plus. Looks great, fits fine, functions terribly.

I have a 2018 Carbon comp diverge. I thought this was a pretty cool product. I chatted up my local sales people with it for a while to make sure that it would fit my application. I was concerned because I have 650b tires On my bike. Several of the sales people converged and decided that I could fit that tube inside of this box. I'm telling you if you have 650 B inner tubes there is no way it will fit in this box and you'll be able to close it. Again looks totally cool and really wish it would've worked my application but I ended up taking it back because what's the point of having this box if I also have to have another one just to hold the inner tube.

Does what its supposed to, looks pretty cool imo. Decent weight with the possibility for further reduction. Weight 404g full Weight breakdown: Empty SWAT box - 164g , Tool - 52g , Co2 cartridge - 59g , Tire lever - 12g , Co2 head - 9g , Specialized tube - 99g , Tube band - 9.5g I got an ultralight Conti tube and I used electrical tape to hold the the tube down. Also I think you could get a lighter Co2 canister?

Fit nice, seemed like a good idea to maintain aerodynamics but you have to sacrifice one of two bottle holders. Replenishing fluids on a long ride is much more important than having a slick place to store a tube and a CO2 cartridge. If there were an extender to get another bottle holder above this on the seat tube, then my comment would be moot.

Running 700 x 43 tires, running tubeless. Not sure the tube that comes with the kit will be of much use as it is for 700 x 23 -25 tires. The kit fits my Diverge Expert with no problems, easy to install and get the kit into the right position via the slotted washers. Trying to think of how I can also put a couple of tire plugs & the tool for inserting them into tubeless tires in case of a flat into this kit.

Honestly, I bought this simply because it looks cool. Now, obviously there are the usable benefits too. The build and components are excellent. The fit is snug to the frame with a flapped rubber outer layer too. There are sometimes complaints about it only containing a thin lightweight inner tube - I believe the tube included is intended to get one by in a pinch; not set them up with a larger/thicker full-on tube of their liking. Also, another review says it does not fit the Diverge and that's completely false - Try a carbon fiber (which these are made for) frame. It fits my 2019 like a glove. I really have no complaints about this as it looks great and functions just as it was intended.

Great product, very convenient and fits right in. Needs a little bit more room.

Perfect fit easy to install

Diverge owners beware, this does not accept tubes bigger than 25c. Plan to carry them some other way. All in all, I still use all the space in there by stuffing gels where tubes are supposed to go.

I have one on my 2017 Roubaix and one on my 2019 Diverge. Both fit great and free up storage in my saddle bag. One recommendation tho - stay with a Specialized inner tube in the box. Thicker tubes don't fit.
