Hello, my first post. I've used forums for years but this is my first cycling one. I'm looking for some advice please? It's time to buy a new bike and I'm not sure what type to buy. Most of my cycling is done on the road, cycle track etc and for seven years I've used a Specialised A1 Hardrock which I've altered to better fit my needs. It has higher bars, Nimbus tyres, a larger front chainring etc. However I do sometimes batter down the odd feild or along very rough tracks. My problem is that I don't know whether to buy another mountain bike or a hybrid. I've looked at the Scott Sportster bikes and they seem very well suited to 90% of my cycling. What I don't know is if a bike like this will be tough enough to take the ocasional harsh tretment it might get. My buget is about four to five hundred pounds. Any advice would be welcome. Thank you in advance, Colin/Mr Pig.
