Frank,
I think the maximum you are supposed to run in there is 14 lbs and it
is easy to get way out of range very quickly using some air
compressors without regulators etc and without great care .... I think
I just saw Thomas selling one of those little syringe pumps .... Some
of the pumps that are sold for this purpose have special fittings to
allow removal with a minimum of lost pressure.
Soooooooooo I am not contradicting the "small hand pump"
recommendation, (to each his/her own). I hope anyone that does this
makes sure that they have a suitable means to adjust and measure the
pressure ...... annnnnndddddd I would also hope that the goal is to
achieve proper static and rider sag measurements. Whether you are
running stock or aftermarket suspension components IMHO you need to
get these measurements adjusted properly. I know that when I was
really getting upset with the "floating in space" feeling at speed I
took these measurements and ended up with 1 3/4 and 2 1/4 approx for
static, (just the bike), and rider sag.
Adding air or adjusting the spacer was the only way I had to adjust
the static measurement and I ended up at 7-8 lbs to get this around 1
1/4 inch, (I was shooting for 1 1/8 etc). After obtaining the static
measurement I wanted I checked the rider sag and it was 1 3/4 inches
..... which was sorta OK ... (I was looking for 1 7/8 .. about 1/3 the
total suspension travel). What is notable here is that "my body" on
the bike compressed the front springs the same amount without regard
to the static measurement I started with ....... I "lucked" out
because the "stock" spring weight was pretty close to accommodating
"my weight" , (actually just a little soft .. to be perfect "for me"
at 160 lbs I would need 1/4 inch less compression when I sat on the
bike ... this would have allowed me to achieve 1 1/8 - 1 7/8
static/rider measurements I was looking for). I suspect that someone
weighing in between 140 and 150 lbs would be perfect for the stock
springs, (I have aftermarket replacements to go in but am lazy and
have not installed them yet).
So ........ I think it is important to note as well that if someone
weighs "more" than I do that they are never going to obtain the
correct rider sag measurement unless they have a spring with a stiffer
rating ........ they can put spacers in until the hardware store runs
out of PVC or add as much or as little air needed to obtain the proper
static sag measurement ........ buuuuuttttttttttt that will have
little impact on the compression that occurs when you sit on it ......
and the resultant "rider sag" measurement.
IMHO as always ........ (flames !! flames !!!!! ouch ..... )
