Pretty much as the title says I'm on a hard tail with 100mm forks.

Thanks Ben

Is this a serious question? If so it's worse than the 'what tyres' threads.

Anyway, assuming it's not. Depends. Depends on how heavy you are, the geometry of the frame, the tyres you're using, the rubber compound in said tyres, whether you're using a 26 or a 29er or something else (shudder) the moisture content of the ground and atmospheric pressure. And that's just off the top of my head.

Start at 35psi and if that's too soft and the bike feels 'squirmy' put some more in, if you're finding the bike loosing traction on climbs and corners etc, take some out.

Nah I tried 699, kept getting pinch punctures. Maybe if you went tubeless.

That's silly. You'd have to keep pumping all the way round. Start at 2000 then let 1 out every mile. That way you can leave your pump in the car.

That's silly, because if you puncture, you won't be able to blow it up again.

I've used 32.77935471 in the front and 34.98365 in the rear before, HTH.

Some, if that's not enough then some more, if it's too much then a bit less...

Seriously, come on now.

"It was a question that I was expecting a proper answer too "
Probably because you asked specifically about Llandegla

If you'd asked what psi for mountain bike trails or something you might have got more useful replies
Also if you'd said what you currently use

If it's Giant or Specialized, then your bike isn't compatible with the PSI standard.

Measure the radius of your wheel, then times it by the circumfrence and finaly divide it by two and you should be somewhere near...

No, it wasn't.

If you were serious when you asked it, you are very silly.
Because this is a very silly question.

Start at 5psi and gradually increase until your rims stop scraping on the ground ๐Ÿ˜€

Bit more than if you we're riding round a shop but not as much as a bmx

Perhaps there's a niche for an app that appeals to the psi-conscious. I'd call it iPsi and it would predict tyre pressure based on gnar rating, suspension travel, rider weight, location and environmental conditions.

Try and be more helpful chaps. No good suggesting tyre pressure and not even stating whether that pressure is on a cold tyre or one that has ben running a while.

The perfect pressure is midway between too soft and too hard on the scientific squeeze test using perfectly calibrated fingers.

Obviously! So I run between 30 and 35 bar on my Anthem when at Llandegla. Everywhere else, it'd be more like 35 down to 30.

Steady on, I've only just thought of the idea let alone how to pronounce it!

35 psi then +/- 5 psi depending how things feel, rider weight, tyres etc.

Just don't go too low on the stony bits to avoid pinch flats ๐Ÿ™‚

My serious answer....

The same psi as your last off road ride

Or 30 psi

But for future reference its not really a question that anyone else can answer without alot of imfo'

The correct answer is sell your hardtail and buy an Orange 5.

You should never attempt a trail as difficult as that with a lesser bike.

Whatever you normally have in your tyres, Llandegla is nothing unusual. ๐Ÿ˜€
