The Effetto Mariposa Giustaforza 1-15 Fixed Torque Wrench - Deluxe is a precision bicycle tool for accurate, controlled tightening. Its 1-15Nm range, compact fixed head and 0.1Nm adjustment make it well suited to sensitive components and tight spaces. The Deluxe kit includes durable cycling-specific bits, an extension and a practical wrap for organised storage.Key Features and Benefits:1-15Nm torque range with 0.1Nm adjustment: The micrometric scale lets you select the torque required for each bolt. Pull and rotate the black dial to set the value, then release it to lock the setting. This gives you fine control when working with components that need a precise tightening force.Clear mechanical click feedback: A loud click and 3° of free movement signal when the set torque has been reached. This gives you a clear indication to stop tightening and helps prevent excess force on sensitive parts. The wrench is calibrated for clockwise tightening only.Small, non-ratcheting fixed head: The minimal head fits into restricted spaces, such as some seat clamps, where a larger ratchet head may be difficult to use. Its fixed design also makes it suitable for open-end wrench attachments. The included 1/4in hex-to-square adapter allows you to use compatible attachments for tasks such as tightening hydraulic brake hose flare nuts.Lightweight, compact aluminium body: The wrench weighs less than 190g and measures 173mm long. Its low weight reduces the effort needed to hold the tool, which helps you feel the applied force during low-torque work. The short body also makes it easy to handle and store in a workshop or tool bag.Durable mechanical construction: The hard-anodised aluminium body has laser-etched markings and no plastic parts. Its mechanical click system needs no batteries or electronics, which removes the need for charging or battery changes. Each wrench is checked and numbered, and the design meets DIN ISO 6789 and ASME B 107.300-2010 quality standards.Guaranteed calibration tolerance: The wrench has a stated tolerance of ±4% for 5000 cycles. After this period, it should be recalibrated to maintain its accuracy. Effetto Mariposa offers a calibration service at its Swiss laboratory, with a certificate and a renewed 5000-cycle tolerance guarantee after calibration.Durable cycling-specific S2 steel bits: The Deluxe kit includes 25mm bits in hex 2, 2.5, 3, 4, 5 and 6mm, Torx T10, T15, T20 and T30, plus a 3/16in slotted bit and PH1 crosshead bit. The S2 special steel has a surface hardness of 62HRC. This helps the bits resist wear during regular use and provides the sizes needed for a wide range of bicycle fittings.Long bits, extension and wrap package: Three 100mm bits in hex 4mm, hex 5mm and T25 provide extra reach for recessed bolts. A 100mm extension adds further access when a standard bit is too short. The practical wrap keeps the wrench and accessories together, making the Deluxe kit easy to organise, carry and store.Accurate torque control helps protect expensive components and makes routine servicing more consistent. Use the torque value printed on the part or specified by its manufacturer, then select the matching bit and tighten to that setting. Return the wrench to its minimum value of 1.0Nm after use. This simple process helps maintain accuracy and supports reliable work across repeated maintenance tasks.Make the Giustaforza Deluxe part of your regular workshop setup for precise bicycle maintenance. Its compact design, durable construction and complete bit kit provide a practical solution for careful tightening, from routine adjustments to more detailed component work.
