do do do doodoo doo doo :lol:

Wiggle appear to have just flaked on their late nov re-stock date for the marathon winters and are now saying they've no idea when they'll be in so looks like I'm staying on the specialized borough cx's for now.

the rated psi for them is 50-100 according to their product page

what sort of pressure should I be running them on to be best prepared for crappy winter conditions?

and asides from higher risk of punctures and increased rolling resistance what else should I be aware of when running tyres at a lower pressure?

    My rule of thumb is 1psi per kg of body weight, so I guessing you should be running them at max. :wink:

    I would suggest running at the higher end of the pressure range and then if it feels wrong let some air out. Its easier to let air out than put it in.

    You're more vunerable to snake-bites at lower pressures but more rubber on the road should mean more grip.
    Higher pressures = faster ride (less rolling resistance), less likelihood of an unplanned deflation but less rubber on the road may mean less grip.
