I got my bike in Oct this year, brand new. I’ve done about 1,200 miles on it. Since about 600 miles i can hear this metallic noise when I’m at speed or slowing down, but it’s not there when I’m still.It’s had its first service and they didn’t pick any things wrong...and have since popped in shop and they had it on centre stand, put it in gear and accelerated etc, but couldn’t hear it in that test....I thought it could be something to do with the chain as it’s running...I’ve cleaned and lubed it periodically and adjusted the slack, but it’s still there!....so I’m at a loss whether it’s a noise that’s meant to be there or something that shouldn’t....a
Do anybody have any ideas or suggestions on what it can be?..to me it sounds if it’s coming from the middle/front of the bike.
