I have a p7 which is soon to be upgraded with xmc 130 15mm ta forks, and theirfore i will soon be in the market for either a new set of wheels or a front wheel with compatible hub, im unsure as to which rim option to buy, dt 4 or 5, stans flow or crest and mavic 717 etc, i weigh 11 stone 8, and i dont have the nerve for frantic dh type riding, not a race type, just like a bit of mixed trail. Could anyone spare me their thoughts/experience.

Crests sound as though they would be perfect for you

717 IMO.

Ive been doing a little net research and had wondered about the max psi rating of them, 30 something?
