I am curious as to how much range of spring preload adjustment you get with the Hydraulic adjuster. From fully seated to max preload I am getting about 7.6 MM of range on mine.
According to Max McCallister on Traxxion Dynamics website:
The Ohlins hydraulic collar is usually full of air when delivered, and offers little to no adjustment range.
7.6 MM doesn't seem like a lot of range for spring preload.
I never have met Max, but I have been to his shop in Georgia one day and while there got a tour. It is a impressive facility. I have seen NASCAR shops not as nice and as equipped as his.
Either he has a hard-on for Ohlins or he knows what he is talking about.
The full adjustment range is 9mm.
Sometimes the adjusters can get air in them, and Ohlins dealer will be able to
bleed it easily for you to return the missing millimeter or so of stroke.
Usually the worst thing I find is when the springs are changed by some persons
they set them with either too much or too little preload so the the range of
the adjuster is rendered useless. Once again this is an easy fix for an
ohlins dealer. While nothing in this world is perfect the Ohlins adjuster beats "c" spanners in horrible tight places hands down!
As for Max having a hard on for Ohlins, it unfortunately seems so... But I
guess you have to consider that he is not an Ohlins dealer, he is a Penske
dealer. Penske make a fine product, however the Penske model coverage is
rather limited, and now with the introduction of the new generation Ohlins TTX
series Penske and many others do not have a competing offering to revolutionary new design that is winning races.
Worse for Max Ohlins have taken to manufacturing a range of fork cartridges
that compete with his product head on and appear to out perform his
cartridges on the race track by a comfortable margin.
So it seems that he has taken to bagging the Ohlins product at every chance he
gets, pity he couldn't have taken a more constructive path than slagging the
