Took my continental revolution racer in for its initial 6 week service early as was having rear wheel issues. Noticed a few of the spokes were very loose and as a result the wheel was not running true. Edinburgh cycles replaced the wheel with no indication as to why so haven't been able to change my habits. I have been avoiding certain routes now due to the quality of the roads but in the past few days 4 of the spokes have become loose again and the dreaded wobble is back. It is still under warranty as they extended the 6 week service but I am a little concerned. I may have bought an entry level racer but this should not be happening. I am averaging about 130 miles a week. Any advice?
