Refuelling with an energy gel, taking a swig of water, capturing a sunset on camera… Some things just can’t wait until you hunker down for the night. 

Stem Cell attaches to your bikes' stem to provide easy-to-access, storage space for the stuff that you’ll need frequently during your ride. Placed well within reach when you're riding, it works well as a stand-alone bag for day riding or as a part of your cockpit setup on longer bikepacking adventures. 

Constructed from waterproof and abrasion resistant fabrics with a minimalist design in our UK factory, Stem Cell is made to endure the demands of life on the road without compromising on weight. 

A webbing ladder offers endless attachment points around the flight deck; simply cut the VELCRO® strap provided to size. 

Drawcord closure creates a 7 cm extension tube to fit a 600 ml bottle or 750 ml Nalgene; the Stem Cell also fits a Mytimug 650. 

"Is it waterproof?" 

Although highly weather resistant, this product is not fully waterproof due to its stitched construction and drawcord closure. If you are carrying valuables or electronic equipment, make sure to put it in a dry bag.
