No matter how hard you try to pack ultralight, sometimes you just need a bit more stuff to hand; enter Stem Cell XL – a tardis in bike luggage form.

Stem Cell XL provides spacious, easy-to-access, protective storage space for the stuff that you’ll need frequently during your ride.

Constructed from waterproof VX21 fabric with a minimalist design in our UK factory, with protective padded walls to protect your stuff, Stem Cell XL is made to endure the demands of life on the road without compromising on weight.

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

Stem Cell XL is spacious enough to carry a BruKit, camera, a light extra layer, or your lunch; drawcord closure maximises capacity.

"Is it waterproof?"

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

Stem cell xl

Extremely well made, durable, tardis like bag. The velcro straps make it rock solid. I was initially concerned it would get in the way when climbing uphill, but it doesn't as it sits so snugly to the stem. I've used the stem cell to take a shirt, lunch, keys, and phone to work. I use it every day and love it, do yourself a favour and get one.

Really good but better with straps

Just to say I took two of these across the Great Divide in USA/Canada. They are tough and made to last. Some of my stuff got holes in but these look like new after a spin in the washing machine. My only observation really would be that I found them better when you use some sort of buckle strap to lash them to frame from beneath. I used two straps and fed them through the tops of the forks. This means that they don't flap up and down. Other than that they are great.
