Seat Capsule Premio

There used to be a time when we never rode with a saddle bag—the Rules wouldn't allow it—and we wanted our bikes to look sleek and having a pack hanging off our saddle isn't exactly pro. But, when the pros are logging long miles on their training bikes and valuable jersey pocket space is reserved for food and extra apparel, a bag becomes mandatory. As our own rides get longer, afforded by more available daylight, and the lure of gravel exploring creating the very real possibility of multiple flats, we've taken to rolling with a bag and the Seat Capsule Premio from Silca has become our go-to.

The Seat Capsule Premio uses a BOA Closure System with Rail Guard for grip and protection against the saddle rails and its location is optimized for stability and aerodynamics. It fits right underneath the saddle and never rubs the legs or otherwise interfere with your pedaling. As a bonus, since it only attaches to the rails and not the post's shaft, you can run it with your dropper post without it interfering with its travel.

The thermoformed shell creates structure and has two internal dividers for organization. A YKK locking zipper is positioned low on the bag for easy access while it’s still attached to the saddle. The capsule offers more carrying capacity than the seat roll offerings from Silca with an internal volume of 625cc and can easily hold a 29 x 2.35in or two 700c x 30mm inner tubes along with a set of tire levers, multi-tool, CO2 dispenser, and up to three CO2 cartridges.

  • A refined saddle bag for carrying flat fixing gear
  • Thermoformed shell offers structure and protection
  • Boa closure secures the bag to the saddle rails
  • Internal dividers help with organization
  • No hook-and-loop straps to damage post, rails, or shorts

Wanted something unique

I've used it once or twice and have initial impressions

I because bored of the standard looking seat bags and wanted something more unique. I was quite apprehensive after reading the reviews for this product but, I decided to buy it nonetheless. Thus far I have no regrets although I must confess that I've only ridden with it twice. That said, the bag seems to be fine. I haven't experienced any of the issues that others have mentioned. We'll have to wait an see as more rides accumulate.


How much does this bag weigh?

Broke after 3 weeks

I've put it through the wringer

***Update*** Used this product sparingly for about 3 weeks, On my Sunday ride I hit a very shallow pothole going into a corner and heard what I thought was my bottle being ejected but it was actually this bag. I am working on Silca to arrange a replacement. Per Silca the first batch had issues with the BOA wires being tied correctly; this is pretty disheartening because I actually ordered this directly from the MFG and they're still sending out known bad products in hopes that people wont warranty them. I almost gave up on Silca. I ordered and returned both the Seat Roll Premio and The seat roll Grande Americano because they simply couldn't not hold a modest amount of kit without flipping or looking ungainly. I tried this unit out because it has BOA and I have yet to find a seat bag I like that affixed to the saddle rails without wearing out or potentially damaging my bibs (velcro has a tendancy to wear out if swapped between bikes a lot) previously used an eolo wallet. The wallet was fine but with an extra tube and c02 (something I started carrying since I've been doing more long solo rides) it weighed my jersey down too much, you'd think a seat roll would offer more carrying power than a wallet but it was actually worse. Here is whats in my bag 1-48mm Road tube 1-80mm Stem Road tube (There is always someone in the group who forgets they're riding aero wheels) 2-16gram Co2s 1-Lezyne Co2 chuck 1-Topeak 60mm valve extender (best emergency valve extender works with every type of schrader valve) 1-Cut up tire boot (old tire bit) 1-Silca Italian Army Knife That seems like a lot but really its only 1 more c02 and tube than what would be considered a minimum kit so I was disappointed that the largest Seat roll silca makes was unable to carry this modest amount. The capsule looks aesthetically better than It does in photos. It's quite long and pointed it gives my Fizik antares an Arione look with added rear length but its actually not too bulbous. Most importantly it holds everything with a slight bit too spare it would be tight but I'm convinced I could jam another c02 in there or a rema patch kit if needed. It sits off the back of the saddle and doesn't interfere with pedaling even when I'm way back on the saddle. Will update with photos and a 1000 mile review but so far very good. Only downside is that it is less stylish than an empty seat roll premio and it will be a tad bit harder to wash since I don't think you can throw it in the washing machine.


did they give u a replacement that works now?

Great, but lasted 3 weeks

I've used it several times

This was by far my favorite saddle bag immediately after purchase. Sleek aero look and fit into the bike. Great capacity with easy access and no rubbing. Only initial issue was boa dial being quite close to the rails, leaving less space to apply the necessary force to keep it all without shaking. But... did not last 3 weeks in the bumpy roads I ride in (and multiple times I go by road bumps at 25mph+). The wire that goes into the boa snapped on my last ride (400miles only of total usage), as I was going by one more speed bump.

Does the job...with unique looks

I've used it several times

I purchased this for my new road bike because my small Topeak Aero hung down the seatpost too low...not allowing me to use my rear light effectively. This unit has just the right amount of storage for me (easily handling a tube, Co2 cartridge, levers, mini tool,cliff bar, and $20 bill). My riding partner has expressed concern following me...over fear that the bag may suddenly open, hatching an alien. The styling does resemble something out of the Jetsons (for those old enough to remember)... but the boa system suspends it well, it doesn't bounce or interfere with anything....and allows viewing of my rear tail light.

A very Unique Seat Storage Case

I've used it once or twice and have initial impressions

Sounds like a funny title, but several things attracted me to purchase this product. 1. The other storage I had under my seat, which I upgraded to a larger size, kept turning off my new rear Lenyze Tail light which has it's Off/On button on the top of the light, so.......I liked to opportunity of of this Silica bag to not have a wrap around the seat post and be tight to the seat! 2. the next thing is the single attachment with the dial tightener similar to my shoes tighteners. What a snap to install and it fits tight to the movement! As a side looks kind of aero! Judge for your self in the picture! 3. It is a snap to unzip and the bottom comes down horizontal to the ground.......lots of room and nothing falls out when you open it! I very much recommend this bag!
