First of all: The Allroad has recently received a model update. The 2024 model comes with Shimano's GRX820 groupset at no extra cost. Thanks to the 2x crankset, the additional sprocket is less important in this upgrade. The improved brakes require less effort and are therefore an advantage. The endurance geometry remains unchanged, resulting in a semi-sporty riding position, similar to the Merida Silex 700.
Corratec Allroad C2: Seat angle ensures comfort
The weight of the bike is neutral to slightly rear-heavy and the seat angle of 73.5 degrees ensures pleasant comfort. In contrast, the handlebars of the Corratec Allroad C2 are a different story. Similar to the Bulls Machete, you should never keep your arms stretched off-road, but rather form a line between the front wheel hub, grips, shoulders and head.
This is unfortunate, because the handling of the bike is so smooth and balanced that even gravel beginners should be able to cope well with it. A closer look at the gearing options and tyre choice makes it clear that the full carbon bike is probably not designed for demanding trails and ramps. Although it has 22 gears, neither the smallest nor the largest gear has an extreme gear ratio. The gear ratios are fine, as are the rather narrow tyres. If you ignore particularly rough terrain, the only real points of criticism are the cheap brake discs and the wide handlebars: the hand positioning is too internally rotated and the long shifting travel on the left lever is almost impossible to manage without changing your grip. With a softer handlebar with less flare, the bike would certainly have been in the top 3.
The Allroad has a lot going for it. Thanks to the tyres, gear ratio and moderate position, it rolls really well and feels comfortable for longer on firm roads. The rougher it gets, the more it loses this feeling, and even low tyre pressure doesn't help. A rather civilised top all-rounder, so to speak.
