The acceptance of road bikes with electronic shifting is increasing, but models with mechanical groupsets still have their fans. The Basso Astra in the TOUR test.

Basso Astra - robust newcomer

Italian racers are not generally known for their comfort, but are characterised by a sporty riding position and relatively firm handling. However, the brand new Astra wants to disprove this and presents itself as an expert for long distances - even on gravel tracks if desired.

This is mainly due to the typical marathon frame geometry with a long head tube, which puts the rider in a comparatively upright riding position. Never before have you sat more comfortably on a carbon racer from Vicenza; the predecessor still straddled the line between marathon and competition bike.

When it comes to tyre clearance, the Italians have taken current developments into account and have released tyres up to 35 millimetres wide, transforming the Astra into an off-road all-road bike - and offering more suspension comfort than in its standard state with the inexpensive ultra-sport tyres from Conti.

Heavy frame

The stable Basso reveals weaknesses in this discipline: Despite the carbon seat post, whose recess accommodates a rear light from accessory specialist Knog, and the low seat stays, bumps reach the saddle relatively unfiltered.

A major point of criticism is the heavy carbon frame. Massive tube shapes lead to a weight of almost 1300 grams, robust gravel bikes are on a similar level. The highlight - not only for Italo fans - is the equipment with Campagnolo's Chorus ensemble. The mechanical twelve-speed groupset scores with precise gear changes, powerful braking performance and an elegant look.
