Speed Capsule TT

Speed Capsule TT is an aerodynamic, highly water resistant direct mount bag for a top tube, down tube or anywhere else you can mount a storage pack. The bag is designed around a unique, semi-rigid PE board structure that allows it to be both rigid enough to remain, stable, open and accessible when unzipped, and allow it to be smooth and highly aerodynamic when zipped.  

The bag zips with a YKK Aquaguard zipper with spring-loaded locking pull tab to prevent noise or rattling of the zipper pull over rough roads.  Aqua guard zipper also provides ultimate protection when the bag is used on the underside of the downtube for adventure and gravel riding, ensuring that the zipper will both seal the bag from water and dirt, but also that the zipper itself will not gum up or become sticky even after hours of water and dirt exposure. 

A high-strength 200D nylon body with 3M reflective side panels and a weather resistant locking pull zipper complete the structure. We also gave Speed Capsule TT slotted mounting eyelets which allow for 10mm of fore/aft adjustment to help you get that perfect fit behind your stem. If you’re a triathlete, long-distance cyclist, or just like having easy access to your food and other riding essentials on your longer adventures, then this bag is for you.
