2025 | Aspero-5 GRX RX825 Di2 1

READY TO RACE

The all-new Áspero-5 was built for the front end of the race,

and is the most aerodynamic gravel bike ever created. Cervélo

has long been synonymous with aerodynamic performance,

and we’ve brought that 30 years of expertise to gravel racing.

The new bike is a stunning 37 Watts faster than the outgoing

model, and 34 Watts faster than its nearest competitor. With

clearance for 45mm tires, downtube storage, and a threaded

bottom bracket, Áspero-5 is ready to race the second it rolls

off the shop floor. The Áspero-5 made a rainbow-jersey debut

under UCI Gravel World Champion Marianne Vos, and will be

campaigned by some of the most elite bike racers in the world.

SHAPE OF SPEED

Áspero-5 is 37 Watts faster than its predecessor, and 34 Watts

faster than the nearest competitor. Cervelo has long led the

industry in aerodynamics, and we’ve delivered a gravel race

bike worthy of that reputation. The aero handlebar and stem

are responsible for nearly 6 Watts of that savings on their own.

WEIGHT

The new Áspero-5 is 66 grams lighter than its

predecessor, despite adding a significant amount of

surface area to improve aerodynamic performance

MIXED & MATCHED TIRE GEOMETRY

When fitted with equally-sized tires (e.g. 42mm front and rear),

Áspero-5’s handling is stable, confidence-inspiring, and ready for

the roughest courses. To increase aerodynamics even further, and

sharpen handling for less-technical courses, we optimized the geo

for a 4mm tire width differential (e.g. 40mm front, 44mm rear).

DOWNTUBE STORAGE

First seen on the P-Series triathlon bike, we’ve implemented our

industry-leading downtube storage door on the Aspero-5. It’s the

lightest and most aerodynamically efficient system on the market, and

puts a tube, tools, and a flat kit inside the frame and out of the wind.
