Although the hustle and bustle of the neighbourhood could well have been a source of inspiration: A 75 mm stem in combination with the short sloping top tube is perfect for hectic changes of direction in the turmoil of a race. The extra-wide riser handlebar not only creates distance to the rider next to you, but also gives you an overview. If a gap opens up, the XTR Di2 changes gears in a flash and you can react immediately. The bike is agile out of corners. The stiff bottom bracket is particularly noticeable here. In the heat of the moment, the rake-thin seatpost (lots of flex due to the long extension - low top tube) forgives the odd missed root. The only question is how often, because the torsion-prone seatpost head conveys as much confidence as the Reeperbahn at night.
ConclusionThe agile handling makes the Sonora a responsive race bike.
PLUS Powerful and agile handling, equipment
MINUS Tight gear ratio (38/28 crank), seat post twists
The alternative: Same weight, no electronic shifting, 1200 euros cheaper: The Sonora SL rolls onto the racetrack with the mechanical Shimano XTR for 5499 euros.
Professional conclusion: "Very compact bike and therefore agile on the trails and tight corners. With the Rock Shox RS-1 and Shimano XTR Di2, the bike leaves nothing to be desired. Only the riser bar is just too much for me personally."
