A mechanic's tool for the tight spots. The Giustaforza 1-15 Fixed pairs a precise 1-15Nm range with a very small, non-ratcheting head that reaches seat clamps and other bolts a ratchet can't, and the Deluxe version adds a full bicycle bit set in a roll-up wrap pack.

Highlights

• 1-15Nm range with a 0.1Nm micrometric scale
• Compact fixed head for tight spaces
• 1/4" hex-to-square adapter lets you fit open-end wrenches, e.g. for hydraulic hose flare nuts
• Under 190g, 173mm long, hard-anodised aluminium body
• Meets DIN ISO 6789 and ASME B107.300-2010
• Deluxe: S2 steel bicycle bit set in a wrap pack

Easy to set, clear to read

Pull the self-locking dial, rotate to the value you need and release to lock it. At the set torque the wrench gives a loud click and 3 degrees of free movement. Mechanical click operation means no batteries or electronics, and no plastic parts.

Light where it counts

At under 190g it weighs less than half of many wrenches in this range, so at low torque values you feel the bolt, not the effort of holding the tool.

Calibration

Every Giustaforza is individually checked and numbered. The +/- 4% tolerance is guaranteed for 5,000 cycles (5,000 clicks), after which Effetto Mariposa recommends recalibration; its calibration service extends the tolerance for another 5,000 cycles and returns the wrench with a calibration certificate. Always store the wrench at its minimum setting.

Compatibility & fit

For bicycle bolts from 1 to 15Nm, including carbon and other sensitive components. Calibrated for clockwise tightening; for calibrated anticlockwise tightening choose the Giustaforza 1-15 Pro Evo. Always follow the torque value specified by the component maker.
