Shimano Ultegra equipped, the Infinito CV has established itself as one of the world’s most respected and revered endurance platforms. Combining comfort, style and Countervail technology with Bianchi’s inherent race pedigree, the Infinito CV Ultegra is equally at home on a tight and bumpy track or long and lumpy Gran Fondo parcours. Weighing in at just 7.8kg, this bike has rightfully earned a solid reputation as a comfortable, efficient and totally trustworthy all rounder.
All the info….
Jump from a full-on race bike like Bianchi’s Oltre XR4 onto the Infinito CV Disc and the first thing you’ll notice is that the ride is a touch more relaxed. Although the geometry of the new version of the Infinito CV Disc is slightly altered, the stack and reach measurements are virtually the same as before.
The riding position is a little more upright than that of a traditional race bike, although we’re not talking about chalk and cheese here. Far from it. It feels like, in typical Italian style, Bianchi has grudgingly accepted that these days not all bikes can be built to an old school geometry and that concessions have had to be made to newfangled endurance. It’s relaxed, but not too relaxed – like undoing your top button and loosening your tie, but a long way short of going full T-shirt and jeans.
The handling is a little more relaxed and easier to live with too. The Infinito CV Disc isn’t quite as eager to change line as a highly strung bike like the Oltre. The flip side is that the Infinito feels more stable and composed and is easier to keep in check. The longer the ride, the more of an asset this becomes.
Don’t, though, make the mistake of thinking that means the Infinito CV Disc is in any way sedate or boring. This is still a bike that’s primed for action. The bottom bracket area, for example, is really stiff with no wafting around when you get out of the saddle and stamp on the pedals. The bike jumps to it when you demand a bit of extra speed.
Weighing in at 8.01kg (17.7lb), our complete 59cm test bike is light (for a bike with disc brakes) but not mega-light. As we’re fond of pointing out, though, you really don’t need to get obsessed with weight because other factors are of equal if not greater importance. Comfort, for example, is a major consideration on a bike like this and the Infinito has plenty of it.
As you might know, the ‘CV’ in the Infinito CV Disc’s name is short for Countervail, a technology that was introduced to the rim brake Infinito back in 2013. Bianchi has since extended the use of Countervail to several other models since then.
To give you the patter, Countervail, which is exclusive to Bianchi in the cycle industry, is a structural carbon system with a viscoelastic resin from Materials Sciences Corp that’s embedded within the frame’s carbon layup. The idea is that it cancels out road vibration to reduce muscle fatigue and save energy while improving handling and control.
Of course, that’s not just down to frame technology. Bianchi specs 28mm tyres – they’re Vittoria Rubino G+ – and quite a well padded Fizik Aliante R7 saddle, each of which helps to stop vibration getting through. If you want even greater isolation from the irregularities of the road surface there’s now clearance for tyres up to 32mm wide. The rim brake Infinito CV will only take tyres up to 28mm because that’s the maximum the brake callipers can handle.
On the 59cm model (beware of Bianchi’s sizing, it’s not the same as anyone else’s!), with a 575mm effective top tube (the length the top tube would be if it was horizontal rather than sloping), a 590mm effective seat tube (the length it would be if the top tube was horizontal), and a 195mm head tube. The head angle is 72.5° and the seat angle is 73°.
The stack height on this model is 599mm and the reach is 392mm, giving a stack/reach ratio of 1.53.
For comparison, Bianchi’s Oltre XR3 Disc race bike in the same size has a stack height of 580mm and a reach of 396mm (giving a stack/reach of 1.46), putting you into a lower and slightly more stretched out riding position.
That’s not to say that you’re going to find yourself sitting bolt upright on the Infinito; not even close. A Specialized Roubaix Comp, for instance, will put you into a far more upright position, the 58cm model coming with a 392mm reach – the same as you get on the Infinito – and a 630mm stack – a whopping 31mm higher.
The Infinito CV Disc is designed with a PressFit bottom bracket and a head tube that’s home to a 1 1/2-inch lower bearing. Like most new disc road bikes, it uses flat mount brakes and 12mm thru-axles front and rear. The cables are routed internally through the frame and the left fork leg. It’s all very neatly done.
The latest version of the Infinito CV Disc has been engineered to be more aero by using a new integrated-look carbon seatpost. It uses a saddle rail clamp that is adjustable for fore/aft position from +25 to -10mm (from the centre of the post). I found the new wedge-style hidden seatpost clamp a bit of a faff in that it’s quite difficult to micro-adjust the saddle height once everything is in place, but it’s secure enough without any slipping, which can be an issue for some non-round posts.
The frame is also compatible with the Metron 5D combined aero handlebar and stem, although our review bike was fitted with Bianchi’s own aluminium components.
