IMHO the tarmac sl4 is a phenominal frameset that is worth the 1400 price tag alone. Its a bike that just keeps on giving.Ride after ride, climb after climb.
The frame is stiff, fast, yet smooth and comfortable, acceleration is swift, steering is responsive, but not twitchy, it holds straight into corners and goes down hill with great precision. The bike climbs with ease and thats coming from a 17st tank on a bike.
