Snack carrying got easier with Silca and the Speed Capsule TT

by 0

You may have noticed a few gravel bikes with what appear to be bottle boss mounts on the top tube recently. While not exactly prolific, they are certainly popping up a little more frequently. The Bombtrack Hook EXT that we currently have on long term test sports them, for example. The mounts aren’t actually for a bottle cage (they are too close to the stem to allow a bottle to fit anyway), but for a new generation of direct-mount top tube pouches.

Sleek and stable, according to Silca

American firm, Silca is best known for its drool-worthy posh tools and pumps, but it has decided to join the bike luggage game with its take on the direct mount top tube bag – the Speed Capsule TT. As you’ll have guessed, it bolts directly to the frame using those bosses. Silca has also worked hard to build a bit of structural rigidity to the bag, making it easier to access with one hand while still riding. We’ve seen plenty of top tube bags that are a bit floppy when full, which as well as being annoying, does limit their usefulness for on-the-go feeding. The Speed Capsule also comes with reflective side panels and a weather resistant zip.

Not just for triathletes.

You’ll have noticed that Silca is marketing the Speed Capsule TT for those of us who like a swim before their ride and a run afterwards. We reckon it is missing a trick – easy access storage for snacks is a bonus on long gravel rides, and the extra rigidity should help keep everything in shape when bouncing along offroad (we have spent entire bikepacking trips righting a floppy top tube bag).
