Bit of a niche question but interested to hear if anyone else has thought of this before. I recently picked up a 2023 GT Force and went to swap the adjustable chainstay from the short (435) to the long (445) position and started wondering if the extension would add travel to the rear end. My thinking is if you extend the rear axle to a ludicrously short or long position, it would very obviously lead to a more exaggerated arc and therefore more or less travel. I looked around online but couldn't find anything talking about this. It could be that brands don't feel the need to address this as the added travel is only a few mm or so but I thought I'd see what you all think.
It definitely does, but not a significant amount. A good experiment is forget I ever said that and then try both.
Interesting! Thanks for the response
"Affect"
(Or, "Will Chainstay Adjustments Effect a Travel Change?")
While the change in travel is minimal, the change in leverage ratio is also pretty minimal but can be noticeable depending on the bike. On some bikes, I've needed to add a couple of psi to achieve the same sag percentage when switching to the longer chainstay position.
Depends on the typ of suspention and of course the amound of adjustment.
on a 4 bar it will affekt the travel less than on a single pivot
but 10mm wont do much in any case.
