Ortlieb Back-Roller Classic QL2.1 40L Panniers — Pair

Ortlieb Back-Roller Classic — forty litres that outlast the bike you bolt them to

Some panniers are bought twice. The Back-Roller Classic is the one most touring cyclists buy once: two bags of twenty litres, seams welded rather than stitched, and a mounting system you operate with one hand while the bike leans against a wall. It has been the reference in rear panniers for four decades, and very little about it has needed changing.

The detail that gives it away is the fabric — a dense, double-sided PVC-coated polyester with the look of truck tarpaulin. It does not absorb water, it wipes clean with a sponge, and it shrugs off the scuffs a loaded bike collects against doorframes and bike racks. What you notice after a year is that nothing has sagged, frayed or started to leak.

Waterproofing

Rated IP64: dust-tight and protected against splashing water from every direction. The seams are fused by high-frequency welding, so there is no stitch line for water to find. To reach that rating the roll-top must be rolled down three to four times and clipped, which is the motion you use to close it anyway. This covers a day of steady rain, spray from traffic and a night left on the bike. It is splash protection, not an immersion rating — these are not dry bags and Ortlieb does not claim they are.

Mounting system

• Quick-Lock 2.1 (QL2.1), on and off in one movement
• Upper hooks and lower anchor adjust without tools
• Two-component hard-soft hook rail that grips without scratching the tube
• Fits rack tubes up to 16 mm; reducers for 8, 10 and 12 mm included, four of each
• Wider hooks for 18 mm and 20 mm tubes available separately
• Symmetrical cut, so either bag works on either side of the rack

Carrying and organisation

• Internal pocket with zip in each bag for papers, phone and multitool
• Two 75 cm shoulder straps included
• 3M Scotchlite reflector on the rear panel and on both sides
• Convertible to a rucksack with Ortlieb's carrying system, sold separately

Frequently asked questions

Will they fit my luggage rack?
If the top tube of your rack measures 16 mm or less, yes. The QL2.1 hooks are made for 16 mm and the box includes reducers for 8, 10 and 12 mm, which covers nearly every aluminium and steel rack sold in Europe. Measure the tube the hooks will sit on, not the uprights. For 18 mm or 20 mm tubes you need Ortlieb's wider hooks, sold separately — we keep them in stock in Meppel.

Will a 15-inch laptop fit?
Yes, flat against the back panel. The usable internal height is 42 cm and the width tapers from 32 cm at the top to 23 cm at the bottom. There is no padded sleeve, so for daily commuting add a padded case or Ortlieb's internal organiser — a pannier is a waterproof bag, not a padded one.

What does IP64 mean here?
Dust-tight, and protected against water splashed from any direction. Heavy rain, road spray and a night parked outside will not get the contents wet, provided the roll-top is rolled three to four times and clipped. It is not a rating for immersion: do not expect the bag to survive a drop into a canal, and do not use a pressure washer on it.

Can they be repaired?
Yes, and it is the main argument for buying them. Because the seams are welded rather than sewn, a puncture can be re-welded by Ortlieb or an approved dealer. Hooks, anchors, straps, buckles and the hook rail are all replaceable, and Ortlieb keeps parts available for at least ten years after a model leaves the range. We handle spare parts and repair enquiries at L'Hirondelle Bike Shop in Meppel.

Which colours can I get?
The colours listed above are the ones we can source. Ortlieb rotates the range from season to season, so availability shifts: if the colour you want shows as out of stock, write to us. We will tell you what our distributor still holds and how quickly we can get it to you.

How does it compare to the TIDURA version?
Same pannier, two materials. The Classic uses the PVC-coated polyester described above, proven over decades. The newer version is built in TIDURA strong, Ortlieb's own PVC-free material system, woven in the Benelux and coated in Germany. Same QL2.1 mounting, same volume, same factory, same price. Choose the Classic for the known quantity, the TIDURA version if you want the PVC-free construction.
