|   Why no square stancions? Why are they all round? | thirdfinger1
Jan 8, 2002 8:05 PM | | It seems as though fork manafactures want to make stiff forks, right? well then why don't use anything but a round stantion. The only thing i've seen is the square one on the cannondale lefty. Why don't we see any more. it seems like they'd be so much stiffer, especially torsionally. Whats up with this? |
| they had one.....i think.. | ibismojo
Jan 8, 2002 8:17 PM | | I remember seeing something like that in Mountain Bike magazine way back when. it was an English fork. |

| Probably because they wouldn't work well at all | Inclag
Jan 8, 2002 9:45 PM | | Sure C-dale uses them, but they have to use needle bearings and are impossible to service, also they have to use a square stachion because it is single sided, a round one would twist of course. I don't see how it would be possible to make an open oil bath fork with square stachions anyway, or at least logically. Think of how heavy a fork with two square stachions, with bearings in both legs would be. Add to it, that it uses a cartride system for dampening and would be impossible to service by a regular person, plus pretty damn expensice to replace those bearings, and I think anybody with half the brain size of a chimpanzee (I know it's probably spelled wrong) would now see that it's plain stupid and impratical.

Jan 8, 2002 9:53 PM | | Main reason why square stancions are not used is because it is near, if not impossible to keep a reliable seal around squared edges compared to a smooth round edge. |
| couple of reasons... | zedro
Jan 8, 2002 11:39 PM | | square seals arent very common; the legs would most likely bind under torsion or other creating alot of stiction (the lefty gets away with this due to needle bearings); less economical manufacturing; it would actually have a lower strength/weight ratio as far a tube alone does; its stupid idea...
Actually i was thinking of having eliptical tubing to maximise strength where you need it and save weight but really it would be a manufacturing nightmare. |
