RFR Unbrakonøglesæt

This professional Allen key set from RFR is manufactured from high-quality chrome-vanadium steel, often abbreviated as Cr-V steel. The choice of this specific material is essential for the tool's overall lifespan and performance, as chrome-vanadium is known for its extreme strength, hardness, and resistance to both deformation and corrosion. When working on your bike, the tool is often subjected to significant torque, especially when you need to loosen bolts that have been stuck for a long time, or when you need to tighten components precisely. By using chrome-vanadium, RFR ensures that the keys do not bend or break under pressure, and that the edges of the hex head itself remain sharp and precise over many years of use. The silver finish not only provides a sleek and professional appearance but also acts as a protective layer against rust, which is particularly important in a workshop environment where moisture and oil may be present. This set is designed to be a permanent part of your toolbox, whether you are a hobby mechanic or a dedicated cyclist who wants to handle the maintenance yourself. By investing in tools made of chrome-vanadium, you reduce the risk of damaging the bolt heads on your bike, which often happens with cheaper tools made of softer metal types.

The RFR hex key set is a complete solution, containing a total of 9 different keys that cover virtually all conceivable needs for the maintenance of modern bicycles. The set includes the following precise sizes: 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm and 10 mm. This wide range of sizes means you are covered for everything from the very small adjustment screws on derailleurs and brake levers (typically 1.5 mm to 3 mm) to the more stressed parts such as stems, handlebars and seat posts (typically 4 mm, 5 mm and 6 mm). The largest sizes of 8 mm and 10 mm are indispensable when it comes to mounting and removing pedals or crank arms, where great force and a perfect fit are required. All nine keys are supplied in a practical and robust black holder, which bears the text Ready for Race. This holder makes it easy to keep track of the tools, so you can always quickly find the right size in the middle of a repair. With dimensions of 230 x 85 mm, the set is compact enough to be kept in a toolbox or hung on a workshop board, but at the same time large enough to provide the necessary leverage when you work. The organized storage ensures that none of the small keys get lost, which is otherwise a frequent problem with loose tools.

One of the most prominent and functional features of this RFR hex key set is the integrated ball-end, located at the end of the long arm of each individual key. This ball-end is a technical stroke of genius that allows the tool to be inserted into a bolt from an angle instead of only being able to work perpendicular to the bolt head. This is extremely useful on modern bicycle frames, where space is often very tight, or where cables, bottle cages, and frame tubes are in the way of a direct line to the bolt. With the ball-end, you can work at an angle of up to 25 degrees, providing incredible flexibility in hard-to-reach areas. While the long arm with the ball-end is ideal for rapid screwing and unscrewing, the short arm of the L-key is designed with a traditional flat hex profile. This short end should always be used when there is a need to apply high torque to loosen or tighten a bolt completely, as the flat profile ensures maximum contact surface and minimizes the risk of rounding the bolt. The combination of a long arm with a ball-end for hard-to-reach places and a short, strong arm for heavy-duty work makes this set a versatile and indispensable tool for any cycling enthusiast. The precision-ground shape of both the ball and the regular end ensures that the tool always fits tightly and securely in the bolt.
