Maybe wrong tyres

huntsman77

Hi guys I have a focus road bike. I do little enough cycling maybe the cycle way once a week probly 40km. Problem is when I go on road I find it very uncomfortable seems like if you hit the tiniest pebble just vibrates up through the bike. just to solid unless your on perfect tarmac.
Is all road bikes like this do I need maybe tyres with a higher wall or wrong bike thanks in advance.

what tyres are on it, and what pressure are they inflated to?

huntsman77

There 700 x25. It say 120 psi on them I do have them at 100.

magicbastarder

100 could be quite high based on your body weight - what weight are you?
for example, i'm 72KG and inflate my tyres to 80PSI, and usually by the time i get around to topping that up, they've dropped to about 70 (or even 60)
