Interesting… breaking Torx head keys and rounding Torx bolt heads out has always seemed a lot easier to me. Even with great tools and quality parts.

When will Silca debut a professional quality high pressure suspension pump? That would really round out their pump options. I’m thinking slightly longer and thinner barrel bore, top quality medium sized gauge, and a pressure relieving head like the Topeak. And of course that sweet sweet red hose. $100, $150, $300, whatever, make it happen.

Silca is a very interesting company from a product design/applicability they make a combo of the silliest stuff along with well thought out products that really solve problems and improve the riding experience. One thing thing that has always been consistent with them is quality though and that’s why I’m such a fan; I don’t need a $400 pump when my lezyne with a digital gauge is 300+ bucks cheaper but their Italian Army knife has been on my back for close to 2 years and looks/functions like a brand new product same thing goes for their Eolo Wallet. Keep on keepin on Josh you’re making good stuff. I’ll take Wera keys over theirs though and for most home mechanics harbor freight is fine for purpose.

Can attest to the Wera allen keys. I was lusting over the Silca set with the shiny wooden box but the Wera set is much cheaper ($34) and seem to have noticeable better quality than the Silca ones.
