At a svelte 7.5L, the Catalyst Pack has easily made its way onto our top-seller list as a go-to gravel adventure bag. Riders with less clearance and narrow handlebars now have a stellar option for stowing gear on their handlebars and under the saddle. The Catalyst Pack is a beautiful mid-capacity handlebar and saddle bag. A more compact option than the Zeitgeist Pack, the Catalyst&';s trim profile allows for more tire clearance and narrower drop bars. The fitted flap sheds the elements and boasts a small flat zipper pocket for quick access essentials like your ride wallet, chapstick and a snack. Utilize the flap&';s daisy chain of webbing to thread a Bungee Booster and stash a layer. The rigid plastic insert offers structure and support for your load. This compact and rock-steady pack is a great option for shredding some gravel and makes a great edition to a lightweight bikepacking rig.
