When you install the Progressive shock, don't you still need to set the "sag" for your riding weight?

The seat height is influenced by the amount of preload... more preload, higher seat....less preload, lower seat.

Spud, if you still have your stock shock, can you measure the eye to eye distance?

I've a shorter inseam than you at 29.25 on a good day I'm on the balls of my feet with the stock shock & tires.
At some point I'll get the thing out on dirt, which means switchng the tires out which might also change the height of the bike a hair....

CSC told me that it tends to add about an inch compared to stock height of the bike...

I guess this is where the "having a sense of humor" comes in.

Put on a lowering link, down an inch.

Put on the new shock, up an inch.

I wonder if I could talk them into a shortie's special - bundle the shock and the lowering link together :P I'm not ready to do a shock/lowering link install yet though....

Yes, you certainly do need to adjust the spring preload for proper sag. After making that adjustment on the Progressive shock, I did not notice any appreciable difference in saddle height.

Ask, and ye shall receive, JB. The distance between the centers of both eyelets on the stock shock absorber is approximately 390 mm.

I understand your reluctance to tackle this project at this time. However, it certainly is best, and easiest, to install both at the same time.

According to the specs of the Progressive shock, eye to eye measurement is 387 mm...pretty close.

Thank you sir!

You're welcome, JB. CSC really did a nice job developing this aftermarket shock absorber.

jb, for a given sag the seat height will be the same. A heavy person will need more preload to get that sag as opposed to a lighter one but, if the sag is the same, the seat height will be the same. The shock eye-to-eye difference is where the extra seat height is coming from. Although it's only 3mm that alone can translate into 1" for the frame to move if the geometry is such. Note that the rear wheel moves 5" or more but the shock does not have nearly that much travel.

I don't think an increase of 3 mm between eyelets will move the saddle height up one inch. I didn't notice any appreciable increase in saddle height after installing my Progressive shock absorber. I certainly would have noticed an increase of one inch in saddle height.

Indeed I cannot fathom how a 3mm difference between eyelets could translate into a 1 inch saddle height increase. Perhaps by the time I might be ready to tackle such a change on my own someone with a similar inseam as i have will have one installed to allay my concerns

On mine with lowering link and Progressive shock and a 5.10x17 rear tire I had it bottom out on the inner rear fender just enough for me to hear/feel it. I could see the scuff on the plastic. So now I know I'm getting full travel and will increase preload abit to keep it off the fender. When I load up for a trip I may need to preload even more. rj

P, This is why this whole suspension business is confusing.

This direct quote from Race Tech:

"The main thing spring preload adjustments really do is change the ride height."

I don't care about all the details, I just don't want to get beat up riding the bike.

Interesting - when I saw the two shocks sitting next to each other, I asked myself the same question - their heights were almost identical - so then how in the world would the Progressive be taller on the bike?

I would expect the progressive has more travel capability upon racheting up the pre-load then the stock shock and maybe that would raise the bike? Am I right here Spud?
