Lifetime Warranty


The SILCA Lifetime Warranty covers products from manufacturing defects for the lifetime of the user.  It further covers the function of all hard parts for 7 years from the date of purchase.  Expected wear and tear is not covered.  Learn more about warranties.

     Seat Capsule Premio is our BOA® powered saddle bag option for those that prefer more structure and internal volume than what a seat roll has to offer. A high-strength thermoformed shell creates a modular structure with two internal dividers that help keep everything organized. The capsule is secured to the bike using the BOA Closure System, and features Rail Guard for superior grip and protection of the saddle rails. The zipper is a YKK locking model that bisects the lower third of the bag. Our designer chose this low position to make it easier to access the bag while it’s still attached to the saddle; a key difference between a seat bag and a seat roll.

    Nifty Spare Bag

    Okay, this will readily hold a spare tube, two CO2 cartridges, tire irons, a multi-tool and an ECOLO Regulator. Fits snugly under my saddle and the BOA system holds the bag well in place. What's also great is it does not block my Garmin Varia Radar unit.

    I purchased this to use for Dirty Kanza and it worked perfectly. I was able to store two tubes, chain tool and tire lever.

    Nice and sleek bag

    Fits okay Worried about the string mechanism and how it is to replace in case it brakes.

    Better than I could have hoped.

    I got this bag for my MTB specifically because it can hold a giant tube for 2.5 tires--which it does quite easily, with plenty of room left for a 25g co2 cylinder, inflator, and tools. I also wanted this bag because it's set back a little, which allows the dropper post full range of action.

    Bag holds CO2 inflator, two extra CO2s, Topeak multi-tool, dynaplug kit, tiny knife and a small tube of Tufo sealant - comfortably too, I am able to zip it all up without fear of busting the zipper. BOA holds perfectly - the bag never sways or comes in contact with your thighs. Bought on clearance for $36 I believe - it's a steal. Really well made.
