Just a quick question I am in the market for my first road bike, (always had mountain living infront of a wood in south wales) and took a liking to BTWIN. Only problem is I cannot choose between the Alur 700 (great bike spec for the price) and one of the Machs 720/740 respectivley. Are the Machs well worth the additional 400-600 pound? Or would the Alur more than suffice? In theory it would but how about in the flesh. Thanks. Ryan.
