My LBS has suggested that if I'm upgrading my bike that I should consider one of those two. I seem to be hard on rims (though I hope I have learnt my lesson about keeping them clean now), so they thought something with disc brakes would be good. My current bike is a Dawes Saratoga Deluxe - a 17 in one, though as I have raised my seat height quite a bit since I first got it, he thought the 19 in might be better for me (5' 6" female, with longish arms), though he did suggest I would need to replace the stem - for something a bit less flat. He also said I would probably need a different saddle too. Is there any other bikes I should be considering? perhaps upto £600? I'm slightly worried that disc brakes will be too sharp in braking terms - is that a problem? I will be putting on mudguards and a rack (along with my bell of course!!) I have suspension on the front currently - I'm hoping I won't miss it. Not understanding a great deal about the spec, I'm assuming that Zero has better components to make the difference in price, but with all the hills in Bristol I think I might like having the extra gears. It will be used for commuting - anything from 5 to 20 miles. Any advice/comments appreciated - thank you.
