You need to look out for idiots giving rubbish information - 80% of info on the internet is rubbish, 15% needs to be passed by your lbs, 6% was made up on the spot and 4% applies to rowboats, not pushbikes. You can believe the rest.

Mate, go to a few bike shops and buy a bike you can try before you buy, a bike that fits you, a bike that you find comfortable and a bike you can look at and feel both love and pride. You don't have enough to get all twisted about performance or which components are supposedly better. In your case, the bike shop and the support it gives you is the most important thing.

Look at lots of bikes, ride as many as you can, fall in love, hand over your cash, come on here and brag about it
