I have a basic Spez Sirrus which after 3 years hard pedalling (3k miles)seems to be a bit past it.
Chain is slipping when putting high pressure on the pedals and chain is aso a little too loose.
Need advice on whether its worth getting a replacement groupset (LBS hinted it isn't), upgraded groupset (currently basic Shimano) or new bike altogether.
Any advice appeciated. Thanks.
