The Boa system is invariably what everyone inquires about when they first see this pack, so I’ll just say this right away: it’s fantastic, and I’m amazed it hasn’t been done before. As promised, it holds extremely tight, looks very tidy, and just like on Boa-equipped shoes, a single pull of the dial releases the cable tension completely so you can quickly pull the pack off when you need to access its contents.
Using Boa on a saddle pack at first seems like overkill, but it’s actually a perfect application for the technology. It holds the pack tightly up against the bottom of the saddle while simultaneously cinching up the pack’s contents, and with no excess material flapping about in the breeze.
Despite being perfectly positioned for road spray, the mechanism hasn’t clogged up, either — and even if it does, Boa’s liberal warranty policy will probably cover it.
Otherwise, the pack itself is well designed, with pockets that are ideally sized for the intended cargo — but no more, so don’t plan on overstuffing it. According to Silca, the Seat Roll Premio is only meant to hold tubes up to 700x45mm in size, for example, and that’s for one that’s carefully wrapped.
The three-pocket design is simple, but effective. Some care is required when packing, though, so that everything rolls up neatly.
Either way, what ultimately separates Silca’s tool roll from others is the additional strap that wraps lengthwise around the whole bundle. It seems insignificant at first, but it does a great job of making a loaded-up tool roll look much tidier and neater than other tool rolls that aren’t so equipped.
Unfortunately, there’s no getting around the bag’s premium pricing, but seeing as how this one actually has something to offer that others don’t, it’s at least a little easier to justify the indulgence.
