Hi all, after nine months commutting on my Boardman Comp Hybrid (12 miles a day, 5 days a week) I took her in for a service £45 I thought was good. Utterly shocked that I needed a new chain, new cassette and new brake pads to the total tune of £151.00! Or, one third of the cost a new bike after just nine months. Also told I would need a new front cog soon as this is wearing as well. Is this amount of wear normal in a commuter bike? I cleaned an oiled the chain every couple of weeks admittedly a bit of a slacker here Looks like I'm going to need a book and start doing these things myself just living on the third floor with only a tiny balcony isn't the best way to strip a bike me thinks.
