Endurance racing bikes for around 4000 euros: The Koga Roqa Premium on test

Our sister magazine TOUR has 12 marathon racing bikes for around 4000 euros tested. The Koga Roqa is a road racer suitable for touring that can be converted into an all-terrain gravel bike in just a few simple steps: The frame and fork can accommodate studded tyres up to 42 millimetres wide. The Dutch also have a pre-configured version with a single drive in their programme.

However, if you are mainly travelling on tarmac roads, we recommend the version shown with the double crankset, as the gear range increases riding comfort enormously on longer tours and is not a major disadvantage off-road.

The Koga Roqa Premium is a comfortable endurance road bike

As a marathon racing bike, the Roqa is decidedly comfortable: the riding position is upright, the slim seat post effectively absorbs hard impacts and the very simple but wide Conti tyres also filter out vibrations. A comfortable top handlebar encourages cosy cruising, and the saddle also suited the testers straight away.

If you want to be more sporty, this orientation naturally reaches its limits. The bike is mainly held back by the heavy wheelset, which is difficult to get going when pedalling spontaneously. However, this should hardly bother those interested in a comfortable long-distance road bike, especially as the Roqa offers other advantages in addition to the ample tyre clearance.

This includes the option of attaching mudguards to existing eyelets - with no restrictions on the choice of tyres. There are also attachment points for a pannier rack, a top tube bag and a tool box under the down tube, which means that the bike can be transformed into a fully-fledged touring road bike without any tinkering.

In addition to the Allroad version already mentioned, which is 200 euros cheaper with a single chainring and no front derailleur, there is also an inexpensive entry-level version with mechanical shifting Shimano 105 for 2999 euros and the top-of-the-range Prime version with Shimano's Ultegra Di2, which costs 1000 euros more than our test bike. With carbon wheels, however, it also makes up for the Roqa's only weakness.
