2021 Specialized Crux

When Specialized set out to design a new 'cross rig, they didn't just want to
make another adventure bike with added tyre clearance—they knew they had to
create a purebred racing steed that was fast, confident, lightweight, and
rides like no other 'cross bike out there.

This 2021 Specialized CruX comes spec'd with a reliable SRAM Apex 1 hydraulic disc groupset, durable Axis Elite Disc wheels, and 700x33mm Tracer Sport tyres that hookup over nasty terrain.

  • Starting with the frame, Specialized implemented their Rider-First Engineered™ technology that was first introduced on their Tarmacs. Using size-specific tubes and layups, this technology allows the CruX to feature the same ride characteristics across every size in the range. Not only this, but it also allowed them to significantly drop the frame weight, so the CruX now comes in around a scant 900 grams for a 56cm (*dependent on frame size and color)—over 400 grams lighter than the previous frameset. A light and stiff frame, alone, isn't useful in a 'cross race if it isn't compliant, however, which is why the new CruX also combines stiffness and compliance in all the right places. And to assist with the latter, Specialized lowered the seat collar by two centimetres for more exposed seatpost and cushion for big hits.
  • Specialized also know that cyclocross races are often won in the corners and over the barriers, which is why the CruX geometry takes this into account. The top tube has been designed for easy shouldering when you're hopping off to clear barriers, as it features a large opening to the front triangle and a flat bottom. For stability in the corners and on off-camber sections, the geometry has a low bottom bracket and a sharp front-end. This combination also helps to initiate corners, regardless of the terrain.
  • With maximum mud-shedding ability in mind, Specialized included eight millimetres of clearance on all sides of a 33mm tire, providing plenty of clearance for muddy conditions. After all, frame weight becomes irrelevant when it's covered in 10 pounds of mud.
