Product Information

Cérvelo Áspero GRX RX815 Di2 Gravel Bike

Meet Cérvelo's new range of bikes. Oh, just to note, if you're looking for their new KOM, stage-topping, Grand-Tour winning road race bike then it's better you search for the S5! This is the Áspero, taking everything Cérvelo have learned from their rich heritage on the road and taking it to the beaten path. Cyclists are demanding more from the time they spend out on their bike and lighting up the gravel path has quickly become a popular way to avoid traffic filled roads and agitated drivers. The Áspero comes into its own with what Cérvelo have called the "TrailMixer" front fork design, it allows you to run both 650b and 700c wheels meaning you have one bike for riding on and off the road. This edition of the Áspero has been finished off nicely with Easton components and Shimano's GRX, Di2 groupset. The GRX is custom-designed by Shimano for the gravel path and Di2 makes shifitng even smoother without the need for cables through an electronic design. So get ready to try out something new, leaving the dodgy British roads behind you and heading straight for the beaten track. 

Full Specification



Explore The Trail And Your Limits

Cérvelo's Áspero is not simply designed for pottering around the family off-road cycle routes whilst enjoying some friendly conversation whilst you catch up with an old friend. The Áspero redefines riding on the beaten path, as rocks fly up behind your rear tyre and any sight of you is lost in a cloud of gravel dust. Cérvelo has taken their road race-winning frame and stripped it down, building it back up again to outperform any traditional gravel bike made before it. The frame finds the perfect blend of hill climb smashing weight advantages and rugged durability to deal with anything that off-road cycling has to throw at it. It also remains aero, as is Cérvelo's heritage, to ensure any KOM segments out the way of the road are appropriately dealt with. 


TrailMixer Thru-Axle Design

Cérvelo loves the adaptability of the traditional gravel bike, quickly switching from the fast-paced 700c road wheel to the beefy 650b mountain bike wheel. However, Cérvelo is not so keen on the handling benefits that you miss out on when you make such a change. This is why they have engineered a unique thru-axle that adapts to your choice of wheel and tyre size. They call it the TrailMixer and it ensures that no matter what setup you think is best for the day ahead, the bike still handles as confidently and puts the same smile across your face.
