Cervlo Aspero-5 Force AXS 1
Thats how spero debuted under the characters of the Wednesday Night Rough Club two years ago, and thats how its stayed. And since, at Cervlo, we know that flat out doesnt stay flat out for long without a little help from science, weve come back from the drawing board with a new spero. A faster spero, a lighter spero, anddare we say it - an even better looking spero.
Our engineers like to say, "If it looks fast, it probably is" - but theres some truth to it, and the Cervelo Aspero-5 Force AXS 1 looks fast standing still. No cables in the wind, tubes derived from our library of aerodynamically proven shapes, and just a hint of a cut-out in the seat tube to squeak out just a bit more tire clearance, add up to a bike that proves the adage.
LIGHTWEIGHT SPEED
Some might say aero doesnt matter on a gravel bike, but if youve battled a headwind across an open prairie, the thirty-two grams of drag youll save with the spero-5 come as a welcome respite. Most gravel racing is done without the benefit of a World Tour pelotonor World Tour tacticsand when its your nose in the wind all day, its nice to know your bikes shouldering a bit of the load.
TWO-POSITION ADJUSTMENT
Trailfront-wheel response to rider inputis the most critical factor in high-velocity handling. Flipping the two-position "Trail Mixer" to compensate for the difference in circumference between a 650b and 700c tire maintains consistent handling by maintaining consistent trail figures.
MULTIPLE CONFIGURATIONS
We designed Aspero with clearance for up to 700c x 40mm tires or 650b x 49mm tires. Of course, there are variables - rim width, tire casing, and tread depthwhich will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 4mm of clearance between the tire and frame.
**New Shimano road (not gravel) 12 speed front derailleurs reduce tire clearance in the rear of the frame to 700 x 38c or 650b x 45c.
SRAM INTEGRATED POWER
Red and Force builds include Quarq Zero power meters integrated into the crank. The integration of a power meter results in better stiffness, lighter weight, and improved accuracy over aftermarket solutionsand the DZero delivers power measurement accurate to +/- 1.5%, even in variable temperatures.
