Bicycle & E-Bikes: Stem Video Guide

Each bicycle has a stem. The term stem describes the connection between the handlebar and the fork. The stem has a decisive influence on the driving and steering characteristics as well as the seating position on the wheel. An incorrectly adjusted stem or a stem that does not fit the bike can limit safety and become a risk during rapid rides. The stems available on the market differ in the length and angle of the handlebar attachment to the fork. A longer stem is mainly to be found on sporty bicycles and ensures a stretched seating position. If the stem is shorter, you sit upright and ride optimally, especially in city traffic or on even roads and cycle paths. The length of this connector affects the reaction of the handlebar and can provide a faster or slower responding steering. It is important that you pay attention to the robust quality and the precise suitability of the model for your bike and that you carry out the installation conscientiously.

The stem is primarily used to connect the handlebar to the wheel fork. Since it is available in different versions, it has different influences on the steering behaviour and the sitting position on the bike. Longer stems are used on racing bikes or mountain bikes, while a shorter stem is mainly used on city bikes. A handlebar with a longer stem allows the cyclist to sit bent forward more sportily and is therefore ideal for off-road rides or fast, fast-paced cycling tours. If the stem is relatively short, the cyclist sits more straight and uses a particularly responsive steering system. The faster reaction is due to the shorter distance that the handlebars transmit to the bicycle fork via the stem. If you don’t want to choose between a short and a long stem and want to take advantage of both lengths, you can choose an adjustable stem and integrate the functions of both models into your bike. The adjustable angle allows a particularly ergonomic adjustment of the handlebars to suit the bike tour.

The stem is an important connecting part that is fitted to every bicycle. Whether the chosen stem has an advantage or a disadvantage depends on the correct suitability for the cyclist and his or her demands on the performance of the bicycle. Disadvantages generally only arise if the stem is not suitable for the respective wheel or if it is installed in an unprofessional and insufficiently firm manner. Preset wheels often have an unfavourable angle of the stem and therefore have a negative effect on the back. Passionate cyclists and experienced cycling professionals therefore use the opportunity to individually select the stem and adjust it to their bike as well as the desired riding characteristics and the correct seating position. Especially the angle-adjustable stems convince with particularly high advantages and can be individually adapted to the needs of the cyclist.

When purchasing porches, the quality of the component is at the forefront of all criteria. Only a high-quality and robust component meets the high demands of cycling tours and ensures a secure and stable connection between the handlebar and the wheel fork. Poor-quality stems can promote accidents and break at high loads. Reviews from other buyers and test results from Stiftung Warentest as well as cycling professionals are helpful and ensure that the purchase is oriented towards quality and resilience. Since not every stem is necessarily suitable for all bicycles, compatibility with one’s own bike should be an important decision criterion. The price is rather behind and is not a clue for a component that is as important as the stem as the connection between the handlebar and the fork. Only after comparing all concise criteria is it advisable to compare the conditions of the individual renowned manufacturers and make your purchase at the best price. Secure attachment and easy adjustment of flexible stems should be among the primary selection criteria when purchasing stems for any bicycle.
