I bought a Felt Virtue a few months a go and have had problems with the suspension bolts working loose on more then a few occassions,(doesnt exactly fill you with confidence) has anybody else had problems with this bike

I've know of one that did that, went back to the dealer & sorted it though, might be worth asking where you bought it from incase there's an easy fix?

I'm afraid it's a common problem but can be rectified with a bit of threadlock. Not an expensive fix, but annoying that it's not done at the assembly stage.
