Cervelo Aspero Rival eTap AXS Disc Gravel Bike
Sitting firmly at the racier end of the gravel spectrum, Cervelo’s Aspero Rival eTap AXS Disc Gravel bike brings together a rapid off-road frame with SRAM’s wireless technology, giving a fast and efficient way to travel across any terrain.
The carbon frame and fork can be used with either 700c or 650b wheels, with the fork’s Trail Mixer flip-chip altering the trail accordingly. Clearance is ample for using 42mm tyres with 700c wheels or 49mm rubber with the smaller wheel size, so the bike’s characteristics can be adjusted to suit the ride, race or rider. Despite the frame's undoubted efficiency and stiffness, there is still enough compliance to reduce vibrations, especially when using larger volume tyres.
Reserve’s carbon rimmed 32mm / DT370 wheels are light, strong and fast, with some aerodynamic advantages to boot. The tubeless-ready rim width works well with wider tyres, supporting the sidewalls and allowing lower pressures to be used without fear of pinch punctures. Ever-reliable DT Swiss 370 hubs ensure smooth rolling and good bearing longevity.
SRAM’s longer cage XPLR rear allows the use of a large 44 tooth rear cassette for longer or hillier rides and ties in perfectly with the 12-speed fully wireless Rival groupset. Shifts are communicated to the derailleurs without the need for cables or wires, so are not affected by water, mud or wear and the large shifter paddles are very easy to operate even when wearing full-finger gloves. The finishing kit comes courtesy of Easton with the handlebar and seatpost made from carbon to reduce weight and improve comfort.
