Product Description

In pro cyclocross racing, every advantage counts. Fast starts, tight corners, efficiency and control through dirt, sand and mud. Proven by top World Cup pros for years, the legendary TCX gets a reboot this year with some key updates to make it faster and smoother than ever.

Pro cyclocross racers settle for nothing less than perfection, and this is the machine that meets their demands. The all-new TCX Advanced Pro features a redesigned, superlight Advanced-grade composite frame that’s handcrafted with race-proven geometry and asymmetrical chainstays for optimal power transfer. Its D-Fuse composite seatpost helps smooth out bumps and vibrations with an innovative D-shaped shaft. New for this year is the option to use a 30.9mm round standard or dropper seatpost instead depending on your riding style and terrain. Other innovations include a lightweight composite WheelSystem and tubeless tyres right out of the box; flat-mount disc brakes; and 12mm front and rear thru-axles for total control and fast cornering, sprinting and climbing in all conditions.

Lighter and more efficient
Advanced-grade composite frameset is 17.5 percent lighter than the previous generation. The frame is now 850g versus 1050g, and the fork is 400g versus 460g. Frame and fork torsional/pedalling stiffness remain the same.

Total control
Integrated disc brake technology with flat mounts and thru-axle hubs, combined with tubeless ready Giant WheelSystem, delivers added control in variable conditions and all types of weather.

Smooth ride quality
D-Fuse composite seatpost helps absorb bumps and vibrations, and new this year is the option to switch to a standard 30.9 round or dropper post depending on your riding style and terrain.

Occasionally, without notice, manufacturers change product design and/or specifications.

Cyclocross Bikes Guide


Cyclocross Guide

Cyclocross bikes look like a road bike or gravel bike at first glance, but they are built for racing off-road..

Cyclocross is a fast, furious and fun style of racing that involves riding these bikes on rough terrain, requiring some running, carrying, negotiating small hurdles and lots and lots of mud. This winter sport is often taken to in the off-season by mountain bike and road cyclists to stay on top form. A very athletic discipline requiring the racer to lift the bike onto the shoulder to negotiate obstacles while running. Very popular in Europe, the sport is currently enjoying a resurgence in the UK, USA and Australia. Cyclocross can be raced in very muddy or sandy environments, this requires and improves bike handling skills.

What makes a cyclocross bike?


‘cross bike geometry traditionally has had higher bottom brackets than road bikes to allow for toe clips hitting the floor when unclipped. Modern CX bikes are now closer to road bikes is the basic geometry making sizing a little easier. With steeper head angles than gravel or adventure bikes and shorter chainstays, cross bikes are nimble and agile. High-end race bikes are thoroughbred race machines, with some mid-range models having mounts for racks/mudguards and a more comfortable riding position.

Cyclocross Guide


While there are obvious advantages to racing with a lightweight bike, CX bike frames are usually a bit more durable than road bikes and have clearance to take bigger tyres. with cable routing to suit being slung on the shoulder. They can be built from titanium, steel or carbon fibre, but aluminium is common.


1x, Compact or cyclocross-specific chainsets give a wide range of gearing for frequent changes in gradient. Pure race-bred CX bikes have a relatively narrow gear range as the steepest gradients are carried and the top end speed does not get too high off-road. The simplicity and range of 1x set-ups are now becoming more common with CX bikes.


Cyclocross bikes traditionally had cantilever or V-brakes for power off-road and to give plenty of mud clearance. Some cross bikes have extra mini brake levers on the top of the handlebars for panic braking on tricky terrain. Disc brakes are now commonplace. Mechanical cable operated disc brakes are still powerful but the extra power and modulation of hydraulic systems are far superior.


While there are obvious advantages to racing with a lightweight bike, CX bike frames are usually a bit more durable than road bikes and have clearance to take bigger tyres. with cable routing to suit being slung on the shoulder.

Why buy a cyclocross bike?


Cross bikes make great commuters. Many have eyelets for mudguards and a pannier rack. They're really durable as an everyday bike and you can fit narrower/slick tyres to make them faster on the road.


If you can fit a luggage rack, a cross bike makes a great touring machine, especially if you want to go off the beaten track. Those bikes that do not have rack mounts can still be toured using bikepacking frame bags.

Cyclocross Guide


Cross bikes are often very comfortable so they're a wise option for sportives and other long rides. They might not be quite as nippy as a road bike though.

Everything Else

If you're not quite sure if you'd rather have a road bike, a mountain bike or a hybrid, a cross bike might be the bike for you. They combine attributes from all these categories, so if you're not sure what type of cyclist you are, a cross bike lets you try out lots of different types of riding.
