    It might make sense in a cali canyon, for someone allergic to bumps.

    Would be utterly shit in the UK.

  • I know it has to go in her by law, but its really not that bad

  • what is that fork? rigid made to look like sus? me confused...

  • Looks like a suspension fork converted to rigid by clamping the sliders to the stanchions with seat post clamps.

  • surely is not the most reliable solution

  • They'd probably still slip wrecking the stanchions.

  • but then surely with that much travel, you could only use them with ~20" wheels?

  • The stanchions are almost as long as the main body so something isn't right. Also can't see any sign of mad potatochopping skills.

  • 1: cut down sliders (note the arch is missing, and the bulge which houses the upper seals)
    2: insert spacers if needed to bottom out the stanchions in the sliders
    3: clamp sliders to stanchions to eliminate play
    Simples.

  • Danger of facial death vs Pugsley forks...

    Or even better. Just buy a fucking Surly Pugsley

  • why ruin a fork, which seems like quite a lot of effort, rather than buying a rigid one?

  • I've got an old Marzocchi MXC laying around, so I'd have to ask myself whether converting it was cheaper than buying a rigid fork and selling the Marzocchi. If I gutted and chopped down my MXC, it would probably be lighter than a rigid steel fork, so the competition would be rigid carbon, not cheap rigid steel forks.

  • fair enough, still looks weird though! also, how would one go about ensuring that they didn't slip out the other way? or is it probably clamped similarly to a seatpost (slot cut in sliders, clamp on top)?

  • Dodge as fuck.

  • is it probably clamped similarly to a seatpost (slot cut in sliders, clamp on top)?

    This, you can see the seatpost clamps. Probably doesn't even need a slot if the clearance is close enough, there isn't much force trying to pull the stanchions out of the sliders.

  • Dodge as fuck.

    I don't think so. The fork is shortened, but the overlap remains the same as it was at full extension, so it should be at least as safe as the basis suspension fork if done properly. Seems like a reasonable piece of recycling if you have the inclination and skills to do a decent job. It's never going to be as good as the best purpose built rigid fork, but it's also nowhere near as costly, either in cash or resource consumption. Could be done with a really cheap suspension fork off a BSO, since the cheap and nasty bits are what you dump.

  • ^like the idea.. not the choice of bikes. i really hope they were bent / crashed before that happened to them.

  • ^^ this is from Yamaguchi's workshop. with this chair he is showing that he gives rat's ass about Italian and American framebuilding schools

  • although his school is located in States...

  • Not a single decent part on that bike.

    tires (if they are maxxis refuses as they seem to be), seatpost and fork seem decent

  • It's Scott's bike. And he's not exactly known for using shit parts for his bikes!

    It clearly does what he intended. So if it's in this thread it's because someone doesn't like how it looks – the only reason.

    Admittedly its attached to a wheel with massive tyres. But 2 things rightly or wrongly bother me.

    1) There are lots of conections and material transitions, were impacts will be highly focused.

    2) The resiliance designed into the fork was based on the assumption that big hits would be absorbed by the suspension.

    I cant see it falling apart, for the reasons you've already stated. But I'd be worried that it would fail somewhere after extended use.

  • Assuming I'm being a paraniod bedwetter about the fork. I love it!

    Perfectly set-up dirt drops, and a crazy tyre combo.

  • 2) The resiliance designed into the fork was based on the assumption that big hits would be absorbed by the suspension.

    A sensible fork designer would consider a couple situations where the spring/damper would be out of play, a: an endo at full extension, so a heavy loading at right angles to the fork travel and b: a heavy landing with the fork bottomed out. In effect, you'd design everything above the upper seal as though you were making a rigid fork.
