(') said:Any advice on setting the height of a mountain bike saddle correctly ?
I've only recently started mountain biking after many years road cycling.
On my road bike (hybrid) I have the saddle set so my legs almost, but not
fully, straighten at the bottom of the stroke.
Set the saddle in a similar fashion on the mountain bike (Orange
Clockwork S) and I feel very unstable on rough ground, I feel much better
with it lower. Perhaps it's just my novice lack of skills, i.e. needing
to put a foot down far to often.
It's an issue, isn't it? If you have you saddle set high enough for
efficiency it can be extremely difficult to get a foot down in emergency,
which, in turn, can feel scary on technical sections, especially downhill.
A number of older[1] mountain bikers I know use a 'magic' seat post which
has two positions selectable by a lever on the handlebars. I'm afraid I
don't know who makes these; I know my LBS has fitted a couple, so I could
find out. I've never tried one myself. I /think/ they use a gas lift like
an office chair to raise the saddle from the low position to the high
position. It used to be common to stop at the top of hills to lower your
saddle for the descent, which is why mountain bikes typically have quick
release levers on the saddle clamp, but this has gone out of fashion
because these days if you stop for a couple of seconds you lose races.
But the answer to your question is that you are most efficient with the
saddle on more or less the position you're using, so if you want to ride a
long distance or take part in cross country racing that's what you need.
But it is much harder to get a foot down. So you may find that it makes
sense to have it lower at least while you're developing confidence in your
technique on technical sections.
If you remind me next week I will find out who makes the magic two-position
seat posts.
[1] by which I mean 'older than most mountain bikers', not 'older than me'.
