Does anyone have any experience with the Ortlieb pack or can they recommend an alternative?
I had one on test. I wasn't a fan.
It's big and requires very careful packing if you want to avoid a 'hinge in the middle' situation ... It appeared that a company who makes panniers felt obliged to make something large enough to fit the contents of panniers in.
I (and others) also struggled to get some of the straps to tighten properly ... I recall one afternoon where Mike and me were both pulling, yet the things refused to budge even when Mike swore at them and I gave the whole thing a full-on Paddington Bear Hard Stare.
