In the latest edition of the Serious Grafix GRX Pro gravel bike, Serious really gets serious as a price-conscious performance brand. Gravel bikes are no longer in their infancy. More and more road bike fans and mountain bikers are discovering these versatile racers for riding a mixture of paved and dirt roads. Serious has redesigned its gravel bike for more sophisticated sporty demands, which leaves nothing to be desired together with the usual great price-performance ratio.
The reworked Grafix aluminium frame has now been given a carbon fork. The sporty sitting position allows a speedy gait on paved and unpaved paths. High-quality 35 mm Schwalbe G-One folding tyres on sturdy wheels offer comfort, traction and puncture safety. With the new SHIMANO GRX 1x11 shifting and extremely wide-range cassette, you have all the advantages of the latest 11-speed drivetrain. From easy mountain paths and steep climbs in rougher terrain to speedy sprints on the home straight, you can shift through gears intuitively with only one lever. The SHIMANO GRX Group's fully hydraulic disc brakes are not only powerful under all conditions, they are also an absolute highlight in this price class. The reliable parts from SHIMANO and ZIPP complete the all-round successful package.
The Serious Grafix GRX Pro gives a real road racing feeling with the freedom to shred dirt and forest tracks whenever you feel like it.
SHIMANO GRX - EXPLORE BEYOND
Designed for rides on rough roads, through gravel and mud, so you can ride comfortably and stress-free wherever you want to go and achieve that unique feeling of performance. Shimano's first groupset for gravel riding. Instead of telling gravel riders what they need, Shimano's developers asked them what they wanted. Shimano has listened for two years and spent countless hours talking to gravel enthusiasts from all over the world. They rode on dust and gravel roads and narrow tracks, and crossed streams and mountain passes to get an idea of what a Shimano Gravel group could look like. The result of all these trips and new friendships? First the Shimano Gravel Alliance and now the Shimano GRX - the world's first groupsets with components specially developed for gravel.
The goal is not to dominate the gravel scene or even change its direction. Shimano didn't want to reinvent the wheel. The engineers at Shimano love gravel just the way it is. Shimano simply wanted to give you and your friends the opportunity to ride the way you want with its new groupset. And the GRX does just that.
And last but not least, the developers envisioned a Shimano GRX groupset that would deliver top performance for gravel racing and at the same time offer options that make it affordable for cost-conscious riders. By setting these design goals, Shimano have developed components that are also suitable for cyclocross, bike adventures and almost any similar type of cycling. Simply put, the Shimano GRX is the world's best way to move freely and discover new territory on your gravel bike.
