Osyth Partial Frame Bag Fit Guide

The Osyth shape has been designed around bikes that have a horizontal(ish) top tube, but the sizes fit well on other shaped bikes too. There are even some bikes that will work with more than one size, in which case you can choose between having more clearance for bottle cages or go for the larger size for more space in the bag. Available in 4 sizes, the Wizard Works Framebagracadabra will fit most bikes out there.

The bags come with 3 adjustable straps (4 for the large and XL) that are a little longer than you will need, so you can cut them down to the perfect length. There are two positions for the down tube strap, to avoid sticky out things, like cable bosses. You can also choose to run one or two straps here, depending on preference.

The recycled HDPE plastic bottom helps the bag keep its cute dogfish shape whether empty or full. It also eliminates the need for a rear strap in most cases, however some setups might benefit from having one.
