TOPIC:

I need to calculate the maximum compression of my rear shocks ( chain clearance issues). I was thinking to measure the spaces between the springs and subtract that from the overall length. Does that sound about right or is there a better way?
Thanks

P.s. YSS shocks (E302T)

Subtracting the spaces will give the maximum compression to coil bind but the damper should bottom out on its rubber bump stop before that happens.
The best way is to have the bike on it's main stand or sat on a crate and fit the shocks ( or just one shock) with the springs removed .
That way you can easily move the arm though its full travel to see where the problem lies.

One could also (I suspect) measure the distance from the shock body to the rubber damper to arrive at the same measurement without the need to remove the springs. If all you're looking for is a rough order of magnitude (ROM) this should be fine, but what zed1015 would be more accurate.

If the rubber damper is very soft you might want to add a few mm to see what would happen if you bottom the shocks out hard.

Ok, thanks. Ill give that a go.
