Me, Id go out and ride
Id hazard a guess as its no worse than riding when your pads are worn right down to the metal and I am sure we have all done that at some point without realizing
Whats even worse is the dog walkers who use the Bike Tracks to walk their dogs on, nothing worse than racing down a trail to be confronted by a dog walker who doesnt want to get out of the way
Trust me if I thought it was shit, it would have been taken back to the LBS. You don't need to have a bike for ages to know if tis good or bad, you can usually tell straight away
My lad got a bike and as soon as I rode it I knew it wasn't for me
