Full Suspension, Coming Soon!

Miles Arbour

Really impressed with this frame bag, fully waterproof as advertised. Absolutely no water ingress during a tour around Scotland for 2 weeks where it rained basically everyday. Solid design!



52Hz Model Specific Fit

To ensure a perfect fit with our 52 Hertz line we’ve added product pages below for popular bike models.  If you have one of these bikes just select the model size in the drop down and we’ll send the 52 Hertz that fits that size perfectly.

Please note some smaller sizes are too small for us to make a 52Hz framebag. If you have one of the bikes below but don’t see your size listed we can do a sewn, custom framebag instead.

Lead Time

Please allow 3-5 business days to ship. 

What Packs Best in Your Waterproof Framebag?

Your flat kit; extra tube, tire sealant, tire lever, pump, etc.

Water bladders fill framebag nooks better then hard plastic bottles.

Large food items that need to be kept dry.
