Asia on a tandem

We can now fit a 203mm front disc brake to one of our tandems - but please read the following warning.
When I originally designed the Raven Twin, I had to choose either a comfortable fork, with provision for V brakes, or a fork which would withstand the considerable (and very different) forces created by a disc - I choose the comfortable fork! To make a fork suitable for tandem use, with a 203mm disc front brake, would’ve required an exceptionally beefy fork. I knew how uncomfortable such a fork would be from our 1999 tandem tour in Australia, I hope I never have to endure such discomfort again!
I certainly didn’t wish to produce a bike with forks, which were even less comfortable!
I’ve no worries about our Raven Twin fork, when we hit a cattle grid at 50mph, on our Raven Twin! Yet, when I put an ISO disc mount on a pair of forks, with identical blades, I managed to write them off, on an unloaded solo bike - was I behaving like an idiot? No, I was simply simulating an emergency stop, from 10mph and I was only using a 160mm front brake! Even the most careful and nervous of cyclists should expect to have to do an emergency stop from 10mph. (I still have this fork, if you want to see it). A tandem fork for a 203mm disc must be substantially heavier duty than this!
