The standard for adventure cycling.

From bikepacking the Great Divide Route to putting in a big day on gravel backroads, the Revelate Viscacha is the go-to seat bag for bikepacking and adventure cycling. The bag uses a roll-down opening to expand or compress – comfortably swallowing 6 to 14 liters of cargo. A removable internal compression strap helps to compress cargo to keep it tight and close-in and high-density foam stiffens the front and protects cargo from rattling against the seat and seatpost. The bag attaches with a large velcro seatpost attachment withe seatpost grippers and a dual-position saddle strap that quickly and securely tightens cargo against the seat rails keep it securely lashed to your bike and minimize swinging.

Revelate helped pioneer the modern soft bags used for off-road bike touring and bikepacking. Unlike the racks and panniers traditionally used for road touring, Revelate's modern soft bags are lighter, more secure on extreme off-road terrain and much more versatile – working on all your bikes, and easy to swap out.

13.8 oz. Black with red stitching. Carbon seatpost-friendly. Dimension Polyant 200 denier fabric with reinforcements. Plastic HD bottom sheet and high-density foam inserts. Removable internal compression strap. Dual seatpost anti-slip straps. Coated webbing saddle attachment.

Sizing: Please keep in mind that this is a large seat bag, so check your bike to confirm that you have the space. The Viscacha requires 8 in. of clearance from saddle rails to top of tire and a minimum of 5 in. of exposed seat post length. Fully compress full suspension frames to measure tire clearance.

I used this for a 100 mile point-to-point ride on my road bike where I needed clothes and sundries at the other end. I packed 5 t-shirts, 1 pair jeans, 1 nano-puff Patagonia jacket, 1 pair shorts, 4 underwear, 4 socks, 2 tubes, multitool, and a small tire pump (w gage). I used a front pack to carry the sneakers, wallet, food, and chargers. This was on a carbon bike but I swapped out the carbon saddle and post for metal for this trip. This bag is incredible and perfect for creditcard touring on a road bike. I noticed the weight but no sway and the bike handled very well. Averaged over 17mph for 110miles w 7k feet of elevation.
