BUYER'S GUIDE: Superlight road bikes – Bike Magazine Australia

If Trek’s Émonda doesn’t tickle your lightweight fancy, here’s some alternatives.

Wilier Triestina Zero 6 

RRP: $12,999 (with Shimano Dura Ace DI2 and Mavic Ksyrium Pro Exalith) 

Wilier have been quietly chipping away at the weight of their flagship Zero model. The current variant, the Zero 6, weighs in at a measly 680g for its smaller sized frames. Starting from a base like this means the application of any mid-to-top tier groupset and a set of low profile carbon wheels is going to deliver a bike well below the 7kg mark. 

One downside to all this weight shedding is that the bike comes with a weight limit. If your mass is anything north of about 72kg, this isn’t the bike for you. Wilier recommends a weight limit of 80kg for bike and rider combined. Should your body fit the specifications required, you’ll be rewarded with little to burden you when the road tilts upwards.

Cervélo RCA

RRP: $10,499 (Frame and fork) 

In the carbon fibre arms race that has taken place in bicycle manufacturing in the past 20 years, Cervélo’s combination of ingenious engineers and race-winning test subjects has delivered climber-friendly bike after bike. 

None more so than the Canadian marque’s RCA. Conceived as an invitation for the company’s engineers to push the limits of what’s possible, its eye-watering price tag is matched only by its astonishingly low frame weight. 

Handmade in California, the RCA weighs in at 667 grams without (according to Cervélo) compromising the stiffness or comfort of the Taiwan-made options. After several years of the program, the market concurs. Available in strictly limited numbers, often as low as a few dozen units, their reputation means RCA models sell out quickly. While they can’t provide a guarantee you’ll get up the hill any quicker, you’ll certainly be left with little excuse when it comes to your equipment. It’ll also trim more than a few grams from your wallet, with the frame and fork alone priced at over $10,000.
