The Barlows are not a direct replacement no, they are more road biased but cope fine on towpaths and a bit of dry dirt, the only place you would find them lacking I think is on the wooded singletrack.
If you’re riding a proper mix like that then having two sets of tyres/wheels would be impractical I guess? It’s what I do, as my AWOL is my daily commuter during the week, and although it occasionally ventures onto hardcore and dirt, if I’m planning a more offroad biased trip I’ll swap tyres.
The Triggers are not ‘bad’ as such they’re just quite draggy on road, and when you get a proper lean on they are very scrabbly and let go too easily, and offroad they haven’t quite for enough bite when it’s slippy or muddy.
I guess it’s a case of pick your priorities though 🙂
How are you finding your AWOL? I’m slowly falling in love with mine, it’s a bit of a lump so might go on a diet next year once I’ve worn the drivetrain out, but it’s an incredibly capable and versatile bike and now I’ve finally got everything jiggled around it fits me like a glove!
