I bought my 1st full suss MTB, a Scott 22.  Sadly as I took it off the blokes hands my wife took it off me, to be quarantined for a month to be given to me on my 50th.  I have threatened divorce, torture, financial penury, I even offered sex which, at my age and with her looks is not a small step.

However to no avail and the bile is locked away.  One thing I did manage to do was sit on it, and as I did the seat went from perfect height down to dwarf size with my 82kg on it.

As I can't even look at the manuals - help satisfy my curiosity.. Do you stiffen the suspension and ride at the top, or is it meant to drop down and you ride midway through the travel (meaning setting the seat too high to start?)

TIA, and looking forward to the day I can go from being a fat slow git to a fat slow git on a good bike  

All suspension bikes what is known as 'sag', so it will go down a little bit when you sit on it. I'm not familiar with a Scott 22, I thought they were nearly all round numbers, 10/20/30 etc,  and is it a Spark, Genius etc? That all has a bearing, it should be in the manual what pressure you run. On a Spark it's on a sticker inside the LH seatstay.

It's usually around 15-25% the travel of the bike in sag.

Enjoy the bike.
