Choosing the right size bike
You should choose the size of your bike based on your height, as well as your build (arm span and leg length).
If you are between sizes, the smaller size will give you a more athletic position, while the larger size will give you a more comfortable position.
XS 154 165cm
S 165 173cm
M 173 180cm
L 180 188cm
XL 188 200cm

Is the RC520 MICROSHIFT R10 bike suitable for bikepacking?
Yes, this bike was designed for bicycle touring on roads, including bikepacking. That means you can install light bags, for example on the saddle, on the frame, and on the handlebars. Thanks to its comfort, the RC520 is the perfect companion for long journeys in the saddle.
This bike is not however a bike for travelling. We do not recommend overloading it with larger travel bags on the pannier rack, for example.
