A discipline in its own right, with specialists who dedicate themselves to it full-time from September to January, Cyclocross is a very demanding practice that requires a specific bike. Here is some guidance to help you identify the key elements when choosing your next machine.
What is Cyclocross?
Originally, Cyclocross (or CX) was a discipline practised during winter by road racing competitors, particularly as part of their season preparation. Very popular in the Benelux region, especially in Belgium, and in Northern Europe, Cyclocross has seen growing recognition over recent years and generates great enthusiasm among an ever-wider audience. The discipline remains very demanding, both technically and physically, with races that are fairly short (approximately 1 hour) but contested at a very high intensity.
The characteristics of Cyclocross bikes
Whereas in the past competitors used a road bike simply modified with tubulars and adapted gearing, today Cyclocross bikes are purpose-built: the frames are very compact, with a geometry characterised by a more horizontal top tube (no sloping) to facilitate carrying, wider chainstays, seatstays and fork to accommodate tyres or tubulars in 32 or 33 section (UCI standard) and to handle mud, as well as a more open head tube angle for greater stability.
In recent years, disc brakes have become widespread and are now the standard, replacing cantilever brakes (rim brakes). The rims, in aluminium or carbon, are of low or medium profile (up to 35 mm high) as aerodynamics are not a priority here. On the drivetrain side, the Sub-Compact double chainring 36/46 is the norm.
It should be noted, however, that the single chainring is becoming increasingly popular for its simplicity of use, typically with a 42-tooth chainring. The other advantage of this solution is that it eliminates a front derailleur, whose operation is regularly hampered by mud — a constant presence in this discipline.
Which frame to choose according to my riding style?
Whatever the material, you should pay particular attention to choosing the right frame size, as the top tube is shorter than on a road bike and the bottom bracket is raised, which reduces the seat tube length. Make sure to check the recommended size based on your height, your inseam length, and to a lesser extent, your arm length.
- Aluminium
For occasional riding or for beginners, an aluminium frame is the way to go. Components have evolved to offer high-performing bikes at affordable prices with this material.
- Carbon
More competitive riders will opt for a lighter and stiffer carbon frame in pursuit of performance.
