The Pika™ is smaller version of the Viscacha. The only difference is the side panels are 1.5" shorter in height. It's ideal for more minimalist bikepackers, road bikers, women riding 29ers, full suspension 29ers and other bikes without much tire clearance or exposed seat post.
Many winter bikers are also using this bag for day trips as a place to store a puff jacket or other clothes.
Requires a minimum of 3" of exposed seat post and 6.5" of clearance from saddle rails to tire.
