Hi any help would be great,

I have just bought a 2nd hand spesh enduro sl 2008

I noticed out on a ride the rear shock when compressing it with weight or even just leaning over the bike and pushing it down, when it returns, it makes a heavy breathing noise and become really enoying.

Also there is a 'snapping/clicking' noise coming from near the middle crank only now and again though

any advice much appreciated
