any good suspension advice

[philfingers]

any good suspension advice for later type std issue NC30 stuff.
For instance, i'm 75kg. is there a ideal preload setting for the back. Anywhere I can measure the suspension height when i'm seated. Any suggestions for base settings?
did a quick search but didnt come up with much

You'll get lots of different answers but try 15mm free sag at the back (just the weight of the bike) and about 35mm once you're onboard in your gear. Front sag should be about 30mm-ish with on. Ideally speaking you want the suspension to compress equally front and rear when your weight is added. If it doesn't then your spring rates aren't spot on. The same is true if you struggle with the free sag:rider sag ratio. Whether that matter depends on what you're doing with the bike.

Measuring free sag is easy - Measure from a point on the subframe to the floor, then lift the back up until you reach the end of the shock travel. Measuring with you onboard really needs an assistant but can be done by one person with the bike on stands.

Before you do anything make sure the shock and forks are in a good servicable condition, most are totally shagged these days and fiddling with em does nothing. If you havent had them done and theres no reciepts from the previous owner then thats where id start

thanks guys, i would the damping right up on the back and there's a noticeable difference between full damping and no damping. I'll give the suspension a try once I get some time.
