Fondriest TFZero - Review September 2012

It's a bold statement but, I reckon the TFZero is the current benchmark for top end carbon race frames

Weight: 6560g

If you've got some serious cash to spend on a hand built Italian carbon fibre superbike the usual suspects of Colnago, De Rosa et al are probably topping your list. But should the Fondriest TFZero be on there too?


The TFZero is 100% handmade in Italy, from tube production through to the bonding of the frame itself in seven sizes (48-60cm) plus a full custom option.

In fact each frame is made to order so they're all pretty much custom built anyway. The manufacturing process is called 'tube to tube' meaning the tubes are cut to length, jigged up and then the joints are wrapped with more carbon. Once all this is done the frame is baked in an autoclave to cure the resin. It's a labour intensive method but gives full customisation rather than having to create many moulds as you would with a monocoque.

Low weight and high stiffness is the aim, and with a (claimed) raw frame weight of just 798g (medium) and stiffness levels of 40N/mm both boxes are pretty much ticked.

Places like the BB area, down tube and chain stays are all overbuilt to withstand the stresses and twisting forces applied through them once the bike is being used in anger.

In contrast the seat stays are a much thinner, flatter profile allowing some minimal flex for comfort and reducing weight.

Up front the head tube is tapered as we're seeing on most frames these days, from 1.125' to 1.25' to keep the front end stiff and tight under load. The carbon fork is a full monocoque and comes in at 340g.

It's the hills where the Fondriest really shines, as you'd expect with an all up weight of just 6.56kg (14.4lbs) sans pedals.

Climbing feels effortless thanks to the lightweight Mavic R-Sys wheels (we'll come to them later) and frameset but it's coming down the other side though that the fun begins.

The stiffness from the down tube, bottom bracket and chain stays keep the TFZero tracking beautiful while the slight shock absorbency at the seat stays keeps you in contact with the tarmac on rough surfaces.

My usual test descent is 50+mph with flowing bends and the Fondriest's steering was an absolute dream loading up perfectly as you shift your weight to clip one apex before banking over to clip the next.

With the frame being made to order there are plenty of choices to be made through the dealer before production goes ahead. You can have the frame set up for mechanical or electronic shifting (the cabling is internal whichever way you go), plus you can choose your BB preference – BB30 or BSA, English or Italian threaded.

The dropouts on both the frame and fork are carbon which gives the frame a flowing uninterrupted look. Alloy inserts are used to secure the wheel and when tightened the quick release never actually comes into contact with the carbon dropout.

A 1k carbon layer wrap finishes off the frame and fork and there is a choice of colours for the graphics as well. Well, you wouldn't want to paint it, would you - it'll add weight.

The Fondriest is really easy to live with and you can ride it day in day out with very little in the way of fatigue or niggles. I did back to back 80 milers over 3 days and each morning it didn't feel like I'd been on the bike the day before; pretty good for a race orientated frame.

The Build

The frameset costs £3200 and at the point of ordering you can have it built up with a range of groupsets plus various wheel and finishing kit options.

Our test model was built up with Campagnolo's Super Record 11 speed which is their top tier mechanical group. The basic design of the top three groupsets is pretty much the same but Super Record uses plenty of carbon fibre and titanium to keep stiffness up and weight down.

The Super Record groupset is so light in operation it's more like riding an electronic system as it changes through the gears with just the slightest touch.

The chainset uses the Ultra Torque axle design which sees the drive and non drive side align midway through the BB shell creating a stiff and smooth running drivetrain. Weight is kept down by using hollow carbon cranks which thanks to their slim, elongated profile are very stiff while maintaining a narrow q-factor.

If I was speccing the TFZero for myself I'd opt for a standard 39/53 chainset as the compact here sees the 34 inner ring virtually redundant on all but the steepest of inclines.

Powerful braking is targeted from two angles with the levers themselves being carbon there should be no flex whatsoever under hard braking while Campag's skeleton brakes are among the top performers on the market.

The Super Record jobbies have got a power differential front and rear which makes modulation easier and prevents the rear from locking up especially on bikes as light as the TFZero.

If things do go wrong the combination of these brakes (always a winner in my eyes) and Mavic's Exalith rim surface means that braking is quite simply phenomenal, wet or dry.

Admittedly the bedding in process eats the initial set of pads and they squeal like a pig but the stopping power and modulation means you can brake at the very last second without fear of looking up.

Both the mechs show large amounts of carbon for the bling factor. The rear has carbon cage plates and the upper and lower bodies are made predominantly out of the stuff. Ceramic bearings are found in the lower jockey wheel to reduce friction.

All in the groupset weighs less than 1900g so if you're going after the weight weenie build it's certainly a good place to start.


The wheels are Mavic R-Sys SLR's which are sold as a wheel package containing tubeless tyres and pads. All three components are designed to work together for performance, aerodynamics and stopping power. The wheels are intended for climbing and at just 1370g (1960g inc. tyres) a pair you can see why.

Don't go thinking they are fragile though, they'll take just as much of a battering as the Aksiums or Ksyriums.

The tubs offer huge levels of grip wet or dry with a gradual break of traction as you reach the limit.

The non drive side rear spokes are carbon tubes using Mavic's TraComp technology and while there were some longevity issues with earlier wheels everything seems to be sorted now. Why carbon spokes? Well due to the very high traction resistance of the carbon fibre wheel deflection under load is hugely reduced and of course lightness.

The rest of the spokes are bladed and are made out of the same alloy as the rims. Both use a treatment called Exalith which coats and penetrates the alloy making it stronger and longer wearing, ideal for braking surfaces plus the dark coat makes the rims look pretty tasty.

On the flat the minimal rotating mass from the wheels means the acceleration is rapid and even with Super Record's ability to jump three sprockets at a time you'll still be struggling to keep up.

Once up to cruising speed the TFZero will happily stay there with very little input and the geometry of our size medium allows for a decent saddle to bar drop to get aero while being comfortable.

Finishing Kit

The finishing kit is all from Ritchey's WCS carbon range and very nice it is to. We've seen these on quite a few test bikes in the past and they always perform well. The steerer clamp uses 3 bolts to tighten while up front the bolts are angled allowing for 260° coverage of the handlebars rather than the usual 180°.

Perched atop the Ritchey seatpost is Selle Italia's SLR XC Flow saddle. The SLR is always a favourite of mine so it's always a pleasure to see one adorning a test bike. The Flow has the cut-out to remove pressure from your bits and the Vanox rails are light and strong.

A little bit of flex in the bars takes away any vibration from the road yet sprint in the drops and you won't feel them move at all. I found the SLR saddle bedded in straight away and certainly gave me no issues.


So, have Fondriest managed to achieve the holy grail of bike design – light, stiff and comfortable? In a word, yes. Admittedly it's going to cost you but the TFZero is as close to perfection as any bike I have ever ridden.

It's not just fast in a sprint or fast up a climb - the TFZero is fast everywhere.

Initially it's not as engaging to ride as a titanium, steel or aluminium frame. In fact, swapping straight from the zingy alloy De Rosa Milanino the TFZero felt a little muted and numb but the fact of the matter is the Fondriest is ruthlessly efficient swallowing up mile after mile with little fuss or drama. Give the pedals a kick in anger though and the TFZero comes alive.

You push it a little bit harder, then a bit harder, then harder still before you realise how far away you were from the bike's limits in the first place.

If it was my choice I'd easily take TFZero over the Colnago C59 which is a huge compliment considering what a great bike the Colnago is. The Fondriest just does everything a little bit better though - the old marginal gains theory.

It's slightly tighter in the bends, slightly more shock absorbent, it gives a little bit more feedback and responds just that split second sooner... this all adds up over the course of a ride.

The fact that you never really need to slow down as it'll take corners and roundabouts flat out means you can keep your average speed up by a huge amount, plus if you do have to slow, the acceleration sees you straight back up to speed within seconds.

At around £7.5k for this build it's a massive outlay but it's set the benchmark so high that this bike is going to be at the top end performance wise for a fair few years yet. Think of it as a long term investment.


It's a bold statement but, I reckon the TFZero is the current benchmark for top end carbon race frames.
