The Bianchi Via Nirone 7 Tiagra 2010 Road Bike. Triple butted 7000 series aluminium throughout with hydroformed sections to ensure the best ratio between design and performance.
Well I just recently purchased a "Giant" Mountain Bike and it cost me around $500-$600. But therefore you get amazing quality. If this professional Race-Bike is stated to be in a used, but very good condition, I would personally pay no more than $800 for it. If you have any questions regarding your purchase, simply send the seller as much questions as you want and they should reply with detailed answers. Hope this helps.
