BTWIN ULTRA 900 CF 105 £1400

This distinctively-styled light carbon frameset comes with Junior World Championship stripes on its sleeves. The 850g frame gets a full Shimano 105 transmission and a well-proven Mavic wheel and tyre combo. But can the home brand of French-based sports hypermarché, Decathlon, really deliver race-ready performance for under £1500 or does what it saves you in the wallet bite you in the backside?
