I realize these kinds of questions must pop up all the time, but I haven't been able to find anyone comparing bikes in this pricerange yet, so I hope you'll bear with me.
After 20 or so years of mixed city and mountainbiking, I still know virtually nothing about bikes themselves, but have decided to buy a cyclocross bike, since various sources seem to suggest this would be the best suited bike type for my purposes. These purposes mainly being (in order of frequency): 1) Commuting to and from work and general city biking (in Berlin), 2) longer training and excurion rides on the country roads (paved and unpaved) and light offroad (such as hiking paths), 3) possibly a few multiple-day trek rides.
After much ado I've narrowed the selection down to three bikes, all costing 900 euro:
Ridley X-Bow: http://www.ridley-bikes.com/pd/gb/en...clocross/x-bow
Focus Mares AX 3.0: http://www.focus-bikes.com/int/en/bi...res-ax-30.html
Fuji Cross 3.0: http://www.fujibikes.com/bike/details/cross-302
Any and all tips, pointers and recommendations concerning these three are very welcome! Preferably with some motivations so that I might actually learn something while I'm at it =)
