Cervelo Aspero 700c – Apex XPLR 1

In 2019, spero took the gravel world by storm, heralding a new era of speed in gravel. Fun, but flat out. The new spero remains true to its original brief, but with some improvements: a threaded BB shell, neater cable routing, and a UDH-compatible derailleur hanger for those who want to use SRAMs Transmission drivetrains. And its more aero, of course. In the case of spero, aerodynamic performance is less about pure speed as a result of drag reduction, and more about conservation of energy. After a big day in a headwind, the three watts saved over the previous Aspero might add up to one less energy gel your stomach has to digestWORTH IT.

In addition to the drag reduction, we also dropped the seat stays to give a bit more compliance out back, and reduced front-end stiffness slightly to make the last hours of a long race less painful. Between those dropped seat stays, we added in a bit more clearance for mud, too, taking what we learned from R5-CX (and the Unbound mudfest in 2023). Its a lot of seemingly small improvements, but they add up to a lot. The result is a bike that feels a lot like the original spero, but is faster, more comfortable, and more versatile.
