Do All Travel Spacers Alter Ride Height?

I’ve just fitted 20 mm of Rockshox all travel spacers to a 2012 Reba RLT dual air. The aim being to reduce the travel from 120 down to 100mm. I was expecting this to result in the fork bottoming out 20 mm sooner.

What I’ve ended up with is 20 mm less ride height i.e. the distance between crown and axle is now 20 mm less. Is this correct or have I got a fork suck issue?

It shortens a2c by 20ml

Why would you want a long fork that s less

In travel

Cheers, that’s a relief.

I’m setting it up as a budget DJ fork. The idea being it’s basically a Pike DJ without the Charger damper.

Could keep it as 120mm and increase the progression with volume spacers so you end up using less of the 120mm of travel.
