I’m a surprised at you spending, what, £2.5K + on a bike and it didn’t come with any instructions ???
As far as the shock setting goes, you’ve got it right, start at 25%, then try it plus or minus above and below that a little and see how you like it. Rebound, start in the middle and try a click or 2 each way, you probably had a fork on you HT, it’s doing the same job but you don’t want it as fast as the front or else it will buck you off on big hits ! Matt24K seems to run settings similar to me. I just have the PP at 2 and switch it on for climbs & flat (otherwise bike wallows), off for descend. But I know plenty of others who just leave it off all the time.
For the Forks – check out Fox’s own instructions on their website. Keep it simple start at 25% sag and see how you go. Rebound quickish. Leave the compression off/at zero at first, then increase it a bit when you have the the other settings nice. I’m sure it’s slow speed compression, so you may want a few clicks on to help hold the fork up.
You can’t go far wrong and you are going to enjoy the bike 🙂
But seriously, don’t you get a Fox CD ROM for this with the bike ? My frame came with one (yes an Orange 5) and so did the Fox forks.
