We previewed the Avanti Corsa DR4 DA9000 in September.
Now, we’re preparing to test the machine, one of a range to be imported into the UK by Bristol-based distributor, Paligap. Click here to see more of the range.
At the heart of the Corsa DR4 is a frame woven from unidirectional carbon fibre, with aero-profiled tubes based on research with Computational Fluid Dynamics, and a massive BB86 standard bottom bracket. The steerer tube of the full carbon fork tapers from 1-1/4″ to 1-1/8″.
The flowing tube profiles are further accentuated by neat design touches that include an integrated headset spacer, stays with small depressions to house the quick release levers, a replaceable rear mech hanger that allows the cable to smoothly exit the drive side chain stay, and internal routing for mechanical or electronic cables from any of the major component manufacturers. A handy Allen key mounting point on the non driveside chainstay will enable you to attach a battery.
The frame is dressed in the 9000 series, mechanical Dura Ace groupset (take a step above the DR4 to get the 9070-series Di2); a specification that includes a 53-39 chainset, an 11-25 cassette, and chain from Shimano’s top-tier offering. The mid-range BB71 bottom bracket is the only deviation. Rolling stock comes from the Dura Ace stable: the clincher incarnation of the aptly named C50 (the carbon rim is 50mm deep), shod with Kenda’s 23c Kountach tyre.
The finishing kit is from Avanti’s in-house Zero Attack range. The carbon bar tipped our scales at just over 200 grams, making a valuable contribution to a machine we weighed at 6.9kg; impressively low for an aero profiled machine.
The Avanti Corsa DR4 DA9000 comes in matt carbon with lime green accents, in seven sizes from 50.5cm to 59.5cm, and costs £5800.
