Borrowing the BOA attachment system from their soft roll-up saddle bags, the new Silca Seat Capsule Premio encases your repair kit inside a rigid structure.
It can hold up to a 29×2.35” or two 700x30mm inner tubes (like their new latex ones), with two internal pocket dividers to secure a set of tire levers, a multi-tool, a CO2 regulator and up to three CO2 cartridges. The rigid design and nearly full wraparound zipper opening means it’s easy to access your stuff without removing it, which is the big functional difference between this and a seat bag. On top is rail guard to protect and grip your saddle rails so it won’t bounce or shift, even on a mountain bike. Retail is $46, available now.
