SILCA Seat Roll Asymmetrico | Bicycle Seat Bag + BOA Closure mounting System | Bike Saddle Bag | Saddle Bags For Bicycle | Bike Tool Bag | Bike Bags Under Seat

To address many of the other reviews who complained about the lack of space, I had plenty of space. I was able to fit 2x 20g CO2 cartridges, and inflater, Crank brothers M18 multitool, park tool tube patches, quick link, chain holder, tyre levers, and an extra 700c tube. It feels super nice, feels water resistant, and the BOA makes it tuck up under my saddle really nice. A big reason I got this was because my previous bags had trouble fitting on my aero seat tube, and this just straps to my saddle so it fits perfectly.

I started with putting all the things that I normally put in my pouch, but had to trim it way back for it to fold properly. All my multi-tools were too bulky for it, so I bought a Blackburn Switch 8, which is absolutely the flattest solution, and I cut its holding case to make it fit in the Silca pocket. Now with one tube, the Switch 8, two cartridges, and two bike tire levers it folds up nicely--just like the pictures. However, each time I came to a stop, the pouch is hanging out of its restraints. So I straighten it up and try to tighten even tighter. Doesn't matter, it still comes out, I guess because the restraint is not squeezing it in the middle, but at the 1/3rd mark and 2/3rds are hanging out. No amount of tightness holds it; the vibrations of the ride cause it to squeeze out. I tried turning it the opposite way then intended, and that was worse. Now I use a small bungee cord to assist with holding it in place. That lowers the sophistication appearance. Pretty disappointing that the sophisticated mechanism for attaching it to the bike is ineffective on its own. Additionally, it really sinks in how embarrassingly long it takes to get it put back together and reattached it to the bike when your biking mates are watching and waiting.

I carry a Crankbrothers M19 multitool, a 700x30 inner tube, two tiny tire wrenches and nothing else fits without it being extremely difficult to close the velcro on top and looking like it is going to open up by itself. Not at all as advertised, it would never close or be able to be attached to the seat with all the things in the photos.Also and completely unacceptable, on the first ride I had to stop 4 times to reattach the bag to the seat, it becomes loose and flips upside down until it completely falls. Thankfully, every time it happened, it hit my legs and I did not loose my things.Summarizing, I currently have an extremely expensive bag that I wanted to love but that I can't use confidently because I could lose at any point in time the few things I can fit in it.

Just as described. Well made!

This bag won't stay in place unless you pack it properly, which in this case it means you can only use the middle pocket.If you try to use all 3 pockets, it's going to come off. It'll slide backward, and the BOA will come loose. First time out I tried as in the marketing image and I'm lucky I didn't lose any stuff!Once I figured that out, the bag is solid and does stay in place.

This pack is behind the times in regard to what I carry. Back in the day, a tube and 2 tire levers was fine, which is about all this can carry. These days, I need in addition to the tube and levers - 2oz sealant, a dart for plugging tubeless tires, and a spare Sram battery. That's with leaving the multi-tool at home. Even with half that, the fold-over flap is too short and gives no confidence that my gear will still be there at the end of the ride. The velcro strap is too short to wrap it all up well, too. Basically a waste of money. I wouldn't even give it away for fear of the giftee losing their gear.

This is so far my favorite saddle “bag” solution for repair tool storage. It houses 1 Tubolito road tube. 2 16-gram CO2 cartridges, 1 CO2 inflation head, 2 tire levers, a few Allen and Torq keys, 2 Latex gloves, a tire boot, a tiny box of self-adhesive patches, a small chain tool, and a $20 bill. They are all packed tight and neat and non-obtrusive, comparing to Lezyne Caddy saddle bag that I previously used.Do note: Josh from SILCA posted a very useful video on how to pack Assemetrico properly. It took me a few tries to succeed. But once I figured out, it is beautiful, nice and clean.

The BOA strap is not centered so that the bag slides to side that bag is not supported and eventually slides off. I had to add a 2nd strap to support it to keep it on the bike.

The newer version is built extremely cheap compared to older or original version, also smaller. Disappointing.

Quality product but very expensive. Rolls up neatly. 2x co2 canisters, 2x tyre levers, 1x mtb inner tube and 1x small Muc Off 140ml tubeless sealant all squeezed in below seat
