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 seals using a YKK Aquaguard zipper with a spring-loaded locking pull tab to prevent noise or rattling of the zipper pullover rough roads. The Aquaguard 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 while function properly even after hours of exposure.
