THE FOLLOWING CALCULATION WILL HELP YOU FIND THE RIGHT BIKE FRAME SIZE AND SADDLE HEIGHT:

Road/Gravel Inside leg x 0,66 = Frame size in cm
MTB Size S: 155 – 172 cm body height
Size M: 173 – 182 cm body height
Size L: 183 – 192 cm body height
Size XL: >192 cm body height
Fitness
or
Inside leg x 0,61 = Frame size in cm
Inside leg x 0,24 = Frame size in inches
Hybrid/Touring
or
Inside leg x 0,61 = Frame size in cm
Inside leg x 0,24 = Frame size in inches
Inside leg x 0,885 = Saddle height on all bikes

If you are exactly between two sizes, you'll have the choice: Choose the smaller frame if you prefer a "racing position" and the bigger frame if you prefer a more comfortable "touring position".

See our video step-by-step instructions on how to determine your frame size. We'll explain you how to easily measure shoulder width, inside leg length and arm length yourself.

BACKROAD AL GRX RX400

Ich gebe dem Fahrrad 5 Sterne, weil es für.mich einfach perfekt ist. Draufsetzen und sich wohlfühlen. Ich komme vom 16 Jahre alten, klassischem Rennrad mit 10 cm Sattelüberhöhung. Bei diesem Rad habe ich 2,5 cm Sattelüberhöhung bei 55 cm Innenbeinlänge und Rahmengröße 57 Abstand OK Sitzrohr-Satteloberseite 24 cm. Man sitzt wirklich schön komfortabel und bringt trotzdem gut Druck aufs Pedal. Ich habe wohl kurze Arme und muss mich fast etwas zum Lenker strecken aber alles im Rahmen. Griffmöglichkeiten sehr geil und weich. Ausstattung geht für mich in Ordnung, Ich nehme an, systembedingt ist es schwer den Umwerfer vorne für mehr als 5-7 Ritzel hinten einzustellen (GRX 400). Aufbau von Rose war in Ordnung, Schaltung etwas nach justiert, Bremse vorne hat etwas geschliffen, habe ich leicht nachjustiert aber hab es auch net viel besser hinbekommen. Rad ohne Lackfehler oder Macken, einfach tadellos. Lieferung ging zügig, kam sicher verpackt an. Ich habe jetzt mal 2,5 Bar eingefüllt und es ist einfach herrlich komfortabel, ich fahre am liebsten feste Kieswege und dafür ist es genau das Richtige für mich.

Beide Bremsen schleifen und das Vorderrad eiert. Heißt, leider nicht richtig zentriert. Für ein 2000 € Fahrrad hätte ich mehr erwartet. Schade, dass ich mich jetzt schon ärgern muss und ein neues Fahrad gleich zur Werkstatt bringen muss, um es richten zu lassen.

Category 2

This category applies to bicycles and e-bikes* that meet the conditions of category 1 and are ridden on normal roads as well as in category 2 on unpaved roads and gravel paths with moderate inclines and descents. The tyres are in constant contact with the ground at average speed and they are only occasionally ridden over steps and drops of less than 15 cm. These conditions can lead to contact with uneven terrain and the tyre repeatedly losing contact with the ground. The intended use is, for example, recreational riding. You don’t require any special riding skills.

Average speed 15 to 25 km/h

Height of steps and drops: < 15 cm

*E-Bikes = 250W 25km/h
