Update :My conclusions :
*forget about fox+marzocchi for tandems : maximum allowed pressure way too low for 150 kg or more : over 40% sag, a lot of compression damping reduces sag to 36% .
I tried Ebike+ myself; only positive thing not bottoming out without adding tokens. Ebike+ allows higher pressures than normal forks.(fox not work with weights over 120kg).
*Rock Shox 35mm diameter up to
*120 mm allows pressures up to 194PSI good for 180 kg
*130-140 mm allows pressures up to 163 psi good for 160kg
*150-160 up to 148 PSI good for 160 kg(also valid for th 38 mm ZEB.
Pike 120 easy too find, but a bit too light I fear. Zeb builds too high. Lyrik might be a more stiff option but not available in 120.
A Yari and a gold 35 are heavier, but are thet also stiffer?
*Suntour Aion 35 boost works better than the fox but also too much sag ;: the manual I have says 120 PSI maximum pressure, but there are also manuals where 150 PSI is written:
150 PSI would be the solution for the right sag with the Aion.
Is there really no one else using a suspension fork on their tandem on this forum?
If there is : what fork , what drivers weight, which pressure?
