Gravel bikes have taken the cycling world by storm in recent
years. The concept of a drop-bar bike with fat(ter) tyres and an
ability to tackle rougher surfaces is nothing new, but the gravel
boom has greatly increased the range of options available and
brought these incredibly versatile bikes in to the mainstream.
Most bikes are targetted at "gravel/adventure" and feature a
full complement of rack and mudguard mounts, and are built to
handle load lugging for those bikepacking expeditions.
Cervélo have taken a slightly different tack with the new
Áspero. This is a bike that has more in common with the likes of
the OPEN U.P.P.E.R. and 3T Exploro (or even the 3T Strada).
The Áspero is very much aimed at those looking for maximum speed
on mixed terrain. It'll accept 700c wheelsets with tyres up to 44mm
wide, and 650b wheels with up to a 49mm tyre (there's a clever
'flip chip' in the front dropouts that adjusts the rake to suit
either wheel size).
