    new to DH and need bike setup advice

    Just ordered a new DH bike, just curious about setup. I'm a XC guy so I am a bit clueless on sag, tire pressure, tubes or not, and anything else I wouldn't think of. Some poking around seems to indicate 30% rear, 20% front, 35-40psi and tubes.

    Bike is the new Kona Operator, I bought the cheapest one.

    Depends on what the vendor says for the suspension but you won't know until you ride to tune it.

    For mine, I go with more sag and no compression enabled in the rear and maybe one click of compression on the fork. Don't make the rebound too fast or you can get shot off the bike. Make sure your suspension is even front and rear.

    With tubes you need higher pressure to not pinch flat. Without tubes you can run less.

    You'll need to check your bolts after each ride. Things get looser faster on DH riding than the xc.

    I run tubeless but like xc it's up to you.

    Yah you are about right on sag. Maybe less up front.

    Tubes ditch them go tubeless first ride.

    Tire pressure is a lot of factors. Mostly the dirt wet/dry and how much rock is on the trail etc.

    But I usually start around 30 and just feel the trail. Little front wheel push I take some out till it feels good, same with the rear.

    That's a good 1st Dh bike though you'll like it!

    Thanks for the answers. I'll give tubeless a shot, I should have enough Stan's tape to do at least one rim. New England so there is always rocks, it's more a matter of how many and how fast of a section it is. I'll just do some laps with my digital gauge and tune it in 1psi at a time same as the XC bike.

    Hopefully I love this bike and I can ride it for several years. Easier to have more bikes that way than explaining to the wife why I need a different same class bike.

    I'm a fan of tubeless, but I'm 240lb. Never have any pinch flat problems any more and minimal wheelset problems . I never run more than 35lb, and that's usually max if there's pointy rocks. Less for smoother/softer trails. Sag should be around 30-35% both front and rear, but set it in attack position and not sitting on the seat if you can. Depending on which shock comes on there, double check the spring weight that comes on the bike if it's a coil. Also good tires. Can't go wrong with Maxxis Minion Dual Ply casing.

    You don't worry about busting a rim at that psi? I ran 25psi front and rear at 185 and I'm thinking I can go to 23 easily. Just concerned about destroying rims.

    Tire is a preference thing, also it depends alot on what trails you are riding, Eastcoast rocks vs westcoast would be different. also 30-35% fork sag is way too much, besides the negative effects on the bikes geometry, its guaranteed to feel scary if the trail ever gets fast, rough or steep.

    East coast roots and rocks. Roughly 20% sag which is good geo as you suggested, but harsh and my hands hurt at the end of the day.
