How much do they weigh?
Good question. First, they are Altura not Avenir, I got muddled up. They weigh 850g (on cheap kitchen scales), each bag, tbh that is less than I anticipated. The area with the most weight, unsurprisingly, is the rear insert that provides the rigidity and the metal bar that holds said insert stable. I accept that they are a sturdy, well built product.
So, 1.7kg, not bad on the face of it. But when I checked in the panniers with everything I needed to cross Spain, North to South, the entire weight was 5.5kg. On my return I realised that I'd taken too many tools and duplicated things, MP3 player + phone etc. Also I had 5 different Michelin maps (I like maps). I know I could get down to 4kg inc the panniers.
Panniers weighing 1.7g to only carry 2.3kg is silly.
