Ortlieb Rack-Pack Classic — The Original Waterproof Rack Bag

The Ortlieb Rack-Pack Classic is the reference waterproof rack bag — simple, robust, and built to last a cycling lifetime. A single roll-top compartment, a proven QL2.1 mounting system and Ortlieb's signature PU-coated Cordura construction make it the go-to choice for touring cyclists, daily commuters and anyone who values function over complexity. Available in 24 and 31 litres, in five colourways.

Mounted directly on the rear rack, the Rack-Pack sits low and stable with no swing or rattle. At the destination, the detachable shoulder strap converts it instantly into a carry bag. The roll-top closure seals in seconds and takes barely a moment to open — a system refined over decades of real-world use.

IP64 Waterproofing

Built from PU-coated Cordura, the Rack-Pack Classic carries a full IP64 waterproof rating — completely dustproof and protected against water jets from all directions. The roll-top closure seals the main compartment without any zips, buckles or additional covers. Rain, road spray, puddle splashes: everything stays out.

Mounting System

The Quick-Lock 2.1 system clips to any standard rear rack in a single downward motion and releases with one hand. Hook diameter adjusts to rack tube diameters from 8 to 20 mm using the included reducer set — compatible with virtually every standard rack on the market.

Organisation

The main roll-top compartment opens completely flat for easy packing. Inside, a zippered inner pocket keeps documents, wallet and small valuables separate. Two external compression straps stabilise the load and keep the roll-top secure when fully loaded. The detachable shoulder strap attaches to side D-rings for off-bike carry.

Frequently Asked Questions

What is the difference between 24L and 31L?

The 24L (H42×W27×D22 cm, 630 g) is the compact touring option — ideal for day trips, commuting and light touring where carrying one bag is sufficient. The 31L (H43×W32×D23 cm, 760 g) adds meaningful volume for multi-day touring, heavy shopping or longer commutes with gear. Both share identical waterproofing, mounting and construction.

What is the difference between the Rack-Pack Classic, Free and TS?

The Classic uses traditional PU-coated Cordura construction with sewn seams. The Free is the PVC-free version — same volume and performance, different material composition for a lower environmental impact. The TS (Thermo Shield) uses thermally welded seams for enhanced waterproofing at the stitch lines. The TS also carries a more contemporary colour palette. All three share the QL2.1 mounting system and IP64 rating.

Does the Rack-Pack Classic fit all bike racks?

Yes — the QL2.1 system is compatible with virtually all standard rear racks. The included reducer set adjusts the hooks to 8, 10 and 12 mm tube diameters. Optional QL2.1 hooks allow tubes up to 20 mm. L'Hirondelle Bike Shop in Meppel stocks the full Ortlieb QL2.1 accessory range.

Can the Rack-Pack Classic be carried off the bike?

Yes — the included detachable shoulder strap clips to side D-rings and allows comfortable shoulder carry. The bag is also stable enough to stand upright on its base when set down. For hands-free carry, an optional backpack strap set is available separately.

Is the Ortlieb Rack-Pack Classic repairable?

Yes. All Ortlieb products are manufactured in Germany to exacting repairability standards. Replacement QL2.1 hooks, shoulder straps, compression straps and roll-top closure components are all available through Ortlieb or your local dealer. L'Hirondelle Bike Shop in Meppel can advise on spare part sourcing and repairs.
