Speaking of non-tandem fork usage...
After building up my Cannondale mountain tandem, I realized the Pepperoni fork had to go. But at the time, I didn't have a whole lot of choice in forks. I don't think anyone was offering tandem suspension forks, other than a few boutique makers and I didn't have the cash for one.
Working at the LBS, I happen across a used Specialized Future Shock. Basically a Mag 21. I look it over and think, "Hey, this COULD work!" I'd just run the pressures WAY higher than recommended by the "manufacturer" and hope for the best! (Dodge the exploding top caps!) But wait, there's a complication: steerer tube is too short. That didn't stop me! Nothing that a little ingenuity, spare tubing and a little LocTite won't fix! Long story short, I press-fit on a section of extra 1 1/8" steer tube with said LocTite with a little thermal expansion/contraction as an aid. Worked like a charm. We rode that fork for about ten years without incident. That steerer tube was SOLID! Even folded a front wheel in half during a race when I made an ill-advised sharp steering input/change of direction on a stair-step drop-off. Fork survived unscathed.
Stupid? Most certainly! But what's life, if not an experiment! Happily I'm riding a Fox fork now that's worlds better (still not recommended by the manufacturer though!). That said, I'm VERY conservative when it comes to working on other people's bikes. Like for example when a friend asked me to install his tubulars a few months ago. Nope. No way. That's on YOU, buddy! (And I've installed and raced on enough tubulars to know how to install them properly and safely. But the liability simply is NOT worth it.)
I just read the supplied article and I cannot imagine why you wouldn't go that route. Better safe than sorry! (Coming from me? Hilarious!)
