From micro adventures to multi-day or -week bikepacking tours: the ACID PACK PRO 6 saddle bag was developed in conjunction with experienced bikepackers. This compact bag attaches quickly and easily to the saddle rails and seatpost, and is suitable for more ambitious off-road riding – just check you have enough clearance to the back wheel first! Large reflective details improve visibility in low-light conditions. There's also an attachment for mounting a tail light and an air valve that allows the contents to compress down further. For dropper post compatibility, use the ACID seatpost adapter, available separately.
