Monstermarrow I’d have to disagree with you there, but anyway it is a bit irrelevant to this post as CG has said
for touring, maximum trip a week
I think you’ll see more and more tourers sporting discs. I’ve read several blogs of people wearing through rims on tours and having to take time out to wait for a rim to be posted out to them. It’s a lot easier to pack a spare rotor in your pannier than a rim.
CG – what size is your road bike? We spent ages trying to find DGOAB a disc braked tourer and thought the Tripster was the one but it’s just too long to get the fit right so a custom build is being drawn as we speak.
Don’t discount Ally as a material either the Tripster is suprisingly comfortable while still being sharp and fast – I gave myself a shock when I looked down at the computer while sprinting (on the road) with 35mm ‘cross tyres on and seeing just how fast I was moving it.
