I have both the tour and enduro blackline.
The black line is eyewateringly expensive and if I hadn’t been feeling flush at the time would have got one of the standard enduro bags. That said it feels great when riding, it’s big due tho the back protector, the reason to buy it but as said earlier the slimline profile and way its organised keeps everything stable, one of the best back packs I’ve used.
The tour is massive. Really massive. Great for carrying spares food complete change of clothes for when I ride with my lad. I use it mostly to commute with, swallows laptop shoes clothes tools, everything really, have used as an overnight bag on a few occasions too.
Biggest drawback with the black line for me was that for the same price as the tour there is no rain cover. Less material and features, but black and yellow. I’m a mug for shiny kit.
Love them both and will take a special bag to replace them.
