    Get some conti trail kings great tyre between 30 and 40 psi. Heavier you are the closer to 40 I would go.

    Ask the guys in the bike hut at ballyhoura to set up your fork. There is no right awnser to that question. You will need to get sag and rebound set. Getting a fork set up isnt as easy as a number.

    Sram and shimano cassettes and chains are interchangeable. So ya it will work.

    Hope this helps.

    Assuming you have tubes in your tyres, use as low pressure as you can get away with without getting too many pinch punctures. 40psi front and rear is a good starting point, you'll probably get away with lower in the front. Experiment - and bring a spare tube!

    Air pressure in forks - normal rule of thumb is to set it so that the sag is a quarter of the travel. The sag is the amount the fork will compress when you sit on the bike while stationary. You can probably look up weight/pressure specs online for your fork but I think the above method is better as it doesn't require the gauge on your pump to be accurate.

    The above are both dependent on the rider's weight - the heavier the rider, the higher the pressure should be.

    Tyres - so many choices, Schwalbe Nobby Nic are a decent all-rounder. You may prefer a bigger thread on the front and a faster-rolling rear, e.g. Racing Ralph.
