Designed for long, fast gravel races, Aspero-5 is for those who toe the start line with purpose, and aim to be in the group straightaway. Our engineers like to say, “if it looks fast, it probably is.” It’s a bit tongue-in-cheek, but there’s some truth to it, and Aspero-5 looks fast standing still. The cables are tucked neatly inside the stem and headtube, there’s a hint of a wheel cutout, and all of the tube shapes come from our race-proven library of shapes.

Some might say aero doesn’t matter on a gravel bike, but if you’ve battled a headwind across an open prairie, the thirty-two grams of drag you’ll save with the Áspero-5 come as a welcome respite. Most gravel racing is done without the benefit of a World Tour peloton—or World Tour tactics—and when it’s your nose in the wind all day, it’s nice to know your bike’s shouldering a bit of the load.

Trail—front-wheel response to rider input—is 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 41mm tires or 650b x 47mm tires. Of course, there are variables—rim width, tire casing, and tread depth—which will affect final clearance. We (and the International Organization for Standardization, or ISO), always recommend 6mm 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.

Red and Force builds include Quarq Zero powermeters integrated into the crank. The integration of a powermeter results in better stiffness, lighter weight, and improved accuracy over aftermarket solutions—and the DZero delivers power measurement accurate to +/- 1.5%, even in variable temperatures.
