I'm about to buy my first road bike, please could anyone tell me what the weight of a womens Trek Lexa road bike is please? Also any advice on whether to buy the Trek Lexa 50cm bike or the Beone Leontien Team Replica bike which is advertised on chain reaction They are both around the same price mark however the Beone should be £850 and only weighs 8.8kg.
Am very new to road racing and any help would be appreciated. Thanks
