Calculate frame size
The right size of your hardtail mountain-bike:
The Inside leg length is multiplied by 0.226 and thus you get the theoretical value of the frame size in inch. One inch equals 2.54 cm.
If the theoretical value is in-between two sizes, the following rule of thumb can be applied:
- choose the smaller size when riding athletically
- choose the larger size when riding tour-orientated
How to determine your Inside leg length:
The Inside leg length or stride height is the length of the inside of the leg. The most accurate way to measure your stride length is to use a spirit level and a tape measure or folding rule. Stand barefoot on a flat surface, clamp the spirit level horizontally between your legs and measure the distance from the upper edge of the spirit level to the ground. This value corresponds to your stride length.
Alternatively, you can also determine your frame height based on your height, see the table below. However, the method using inseam length is more accurate.

Frame-size in cm: multiply your Inside leg length by the factor 0.61. Frame size in inch: multiply your Inside leg length by the factor 0.24.If the theoretical value lies between two sizes, the following rule of thumb can be applied:
- Rather the smaller frame size when riding sportsmanlikely
- Rather the next frame in size when riding tour-orientated
- Deduct approx. 5 cm (or 2 inches respectively) of the theoretical size when using spring-mounted seat posts.

Statt es gleich sein zu lassen, baut Shimano im unteren Preissegment leider nur noch Schrott. Wo die alten BB-UN55 Lager noch tausende Kilometer gehalten haben, gehen die hier schon nach nur 1000 km kaputt. Die zwei verbauten 6903 Lager sind einfach zu klein für die Krafteinwirkungen, die bei einem Erwachsenen auf ein Vierkant-Lager wirken.
Average rating of 3 out of 5 stars
Soweit in Ordnung, jedoch irgendwie schlecht abgedichtet: Bei mir drang nach nur drei Monaten Wasser und Matsch ein, wodurch die Achse Rost ansammelte, beim Drehen ein unangenehmes Geräusch verursachte und das Gewinde im Rahmen ebenfalls dreckig wurde. Ich empfehle Käufern dieses Lagers, es regelmäßig zu entnehmen und Lager und Rahmen zu reinigen, um Beschädigungen o.Ä. zu verhindern.

Günstig aber leider nicht haltbar. Der mobile Adapter aus Alu ist zu weich und wird mit der Zeit gebogen. Das führt dazu, dass der Innenlager nicht mehr korrekt gehalten wird. Nach 3 Monaten / 400km hatte das Ding so viel Spiel, dass es schon unangenehm war. Nach 3.5 Monaten / 500km hat der Teil endlich komplett "explodiert" (die Kugeln kamen raus). Schade.

Hat bei mir 4.000km am Alltagsrad gehalten, bei Wind, Regen, Schnee und Sonne. Es ist nicht der beste Wert aber okay.

Wog 350 Gramm auf meiner Küchenwaage, etwas schwer auf das Brompton zu schrauben

Für Benutzung im Singlespeed-Rad absolut nicht geeignet. Nach ca. 5-6 Monaten geht bei jeder Kurbelumdrehung ein Ruck durch die Kurbel und sie entwickelt nach und nach etwas Spiel. Vermutlich ist beim Singlespeed aufgrund der geringen Drehzahl beim Anfahren die Kraft, die auf das Lager wirkt, zu groß für so eine simple Variante (fahre 46/16 Übersetzung). Werde mich jetzt nach was Stabilerem umschauen müssen. Einziger Lichtblick: bei dem günstigen Preis nicht ganz so ärgerlich aber trotzdem nervig, mehr Arbeit und 10€ zum Fenster raus...

Excellent quality for the price!
Average rating of 4 out of 5 stars
Bewährte Shimano-Qualität, „nur“ 4 von 5 Sternen, da Dichtung des Lagers nur durchschnittlich. Nach 5 Jahren mit Winterfahrten (Streusalz) war das Lager defekt und begann zu knacken. Aber erneut gekauft, da im Preis unschlagbar und mit einfachem Radwerkzeug leicht zu wechseln.
Average rating of 5 out of 5 stars
Leichter Einbau. Gewinde machten super Eindruck, Lager laufen super, alles in allem Zufrieden.

Guter Ersatz, leicht einzubauen
