ในThis heavy slimming adds plenty of comfort, with buzz reduced to a murmur, helped by the classy Fizik Antares saddle – though the ride quality would be further improved by 25mm tyres (come on Cervélo, you’ve designed the bike to take them, so let’s have them!). Mavic’s Yksions are decent rubber, but they are slender for 23s.Gearing is spot-on for a fast road machine with a nod to the sportive or endurance rider, combining a 52/36 chainset with a close 11-25 cassette at the back. The latest Ultegra uses the same design as Shimano’s flagship Dura-Ace,
performing just as flawlessly, and aside from the finish and a titanium bolt or two you’d be hard pressed to tell the difference. The alloy aero Mavic Cosmic Elite S wheels are well built and rock solid. As a package including
tyres and tubes they weigh 2380g so aren’t the lightest, but although it has to be said the S3 would fly on higher quality aero wheels, it’s still respectable in this standard guise. For £3300 you are getting an exceptional aero
bike, with a simply wonderful frame. Cervélo has taken a design that was showing its age and infused it with everything it has learnt since. The S3 handles better, it’s more comfortable and the chassis is lighter. It also competes on every level with the likes of Giant’s Propel, Felt’s AR and Specialized’s Venge. It would easily be a five star bike with better wheels; we’d expect more than a £400 set on a bike of this price. As it stands,though, this is one seriously rapid bike that we’ll certainly miss riding once it goes back.
