The Loomer was built around two goals: make a cockpit-on bike case as compact as possible, and make sure that smaller size didn’t compromise protection. The shape tightly fits road or gravel bikes, while a combination of rigid structure, protective panels, foam lining, and carefully placed supports keeps everything secure inside.
We also tried to make use of every bit of space around the bike, adding storage for the things you actually travel with instead of leaving empty volume.

The new Size XS Slim Frame Pack isn’t coming alone. Meet the new, smaller, Slim Top Tube Pack. Aero, and perfectly sized for snacks and ride essentials.
Pre-order is live, shipping early next month!
Think your gravel tires are too wide for the Transfer Case? Try this: put the wheels in plastic bags and they’ll slide right in.
We’ve had lots of questions about whether the Transfer Case will fit modern gravel bikes. They do, and there’s a good chance your wide tires will too with this simple trick. The 150L size is currently backordered, but the 135L is still available and on sale for a limited time. Perfect for this summer’s gravel adventures.
And if your bike has an integrated cockpit that can’t be taken apart, check out the new Loomer, shipping the first week of July.

A small hiccup in production led to a few delays, meaning that the Loomers will be arriving at our US warehouse in late June, and begin shipping in early July. They’re now in a container going across the ocean to our US warehouse. To those that have pre-ordered, thanks for the patience. We know they’ll be worth the wait!
Traveling with your bike this summer? The Loomers are getting close.

Glad to collaborate with on frame bags for the new Sarana; their latest race endurance gravel bike. The goal was to create a storage system that felt integrated with the bike rather than added on afterward.
We shaped the slim, aero bags around each frame size and bolted them directly to the frame. Built for speedpacking adventures without sacrificing the race feel of the Sarana.
We’re excited to see these out on gravel adventures ahead.
