LEXIVON Bike Torque Wrench 1/4-Inch Drive, Newton Meter | 72-Tooth Gear, Dual-Direction Click Type, 2-26 Nm (17.7-230.1 in-lb) | Portable for Road & Mountain Bicycles (LX-190)
LX-190
LX-190 is a 1/4-inch drive bicycle torque wrench covering 2-26 Nm, with 0.2 Nm adjustments and measurement in both directions. Its 8.7-inch length and zippered case suit portable maintenance when the component specification fits; select sockets or bits separately.
LX-190 puts 2-26 Nm settings first, with a 1/4-inch drive and both measuring directions. Its 8.7-inch length helps you plan space for bicycle maintenance.
Set the Nm reading in 0.2 Nm increments and raise the sliding collar to hold it. The 72-tooth head includes a quick-release socket control.
LX-190 includes a zippered protective case and calibration certificate. Select compatible sockets or bits separately; LX-191 includes the 15-piece tool set.
Match the required torque, measurement direction, square drive and working space to the equipment specification.
| Job or attachment | Works | What to check |
|---|---|---|
| Bicycle fasteners with 2-26 Nm specifications | Yes, when specification fits | Clockwise and counterclockwise tightening within 2-26 Nm; follow the equipment maker's torque value. |
| 1/4-inch drive sockets | Yes | Match the socket opening to the fastener and allow space for the wrench. |
| 3/8-inch drive sockets | No direct fit | Match the square drive rather than the socket opening size. |
| Fasteners below 2 Nm | No | Use a lower-range torque tool. |
| Fasteners above 26 Nm | No | Use a higher-range torque tool. |
| Left-hand threaded fasteners | Yes, within range | Counterclockwise accuracy claim is +/-6%. |
| Stuck fasteners and added leverage | No | Do not use as a breaker bar or add leverage devices. |
Compare each component's printed or service-manual torque with LX-190's 2-26 Nm range. Match a 1/4-inch drive attachment to the bolt, then stop at the click. The bicycle label does not establish a universal stem or seat-clamp setting.
The LX-190 measuring range starts at 2 Nm, so a lower specification requires another instrument. Do not force the handle below its marked minimum or round a delicate component's requirement upward to fit the tool.
26 Nm is within the LX-190 range and is its upper endpoint. Verify the component's attachment and direction as well as torque; a pedal, crank or other fastener needing more than 26 Nm calls for a higher-range wrench.
LX-190 measures both directions, with stated +/-4% clockwise and +/-6% counterclockwise accuracy. Select the appropriate ratcheting direction and keep within 2-26 Nm; thread direction alone does not establish the component's required torque.
Check the interface, not just the phrase 1/4 inch. LX-190 has a 1/4-inch square drive; a loose hex-shank bit needs a correctly matched holder. Confirm the fit of your existing attachments before use.
LX-190 is 8.7 inches (22 cm) long and includes a zippered case. Compare those facts with your available storage space. They do not guarantee airline carry-on acceptance or authorize disassembling the head for travel.
LX-190 uses a Nm-first setting procedure with 0.2 Nm micrometer steps. Five of those steps add 1 Nm to the body reading. The inch-pound equivalent is rounded to about 1.8 in-lb, not a whole 2 in-lb setting.
LX-190 covers 17.7-230.1 in-lb, or 2-26 Nm. Keep the two units separate when transferring a bicycle specification; the top micrometer row is Nm and the bottom row is inch-pounds.
LX-190 has a quick-release button, secured-socket mechanism, left/right selector and 72-tooth ratchet. Confirm the attachment is retained before working, and remove it using the quick-release control.
The handle must be held by LX-190's sliding collar after adjustment. Smooth rotation while unlocked is part of setting the tool; if it rotates after locking, stop and have the tool assessed before relying on the selected Nm value.
LX-190 signals the selected torque with a click or impulse. Pushing through that point can damage its mechanism; stop and unload the handle instead of expecting the wrench to block further force.
Pause use and contact Lexivon if LX-190's torque signal changes after a snapping sound. Low-setting clicks can be subtle, but that does not establish that a tool with changed operation is sound.
LX-190 provides 2-26 Nm (17.7-230.1 in-lb) with 0.2 Nm adjustments. LX-180 provides 10-150 in-lb (1.1-16.9 Nm) with 1 in-lb adjustments. Both use 1/4-inch drives and measure both ways; choose the interval and primary unit that fit.
LX-190 includes the wrench, case and calibration certificate. LX-191 includes the wrench plus 12 bits, an adapter and a 3-inch extension. Check the package rather than assuming the LX-190 bicycle name includes that accessory set.
LX-190 has an aluminum-alloy rotating handle. If your job has a material requirement, confirm that the specific component meets it before purchase.
LX-190 includes a calibration certificate. Confirm the date and traceability required for your own work before ordering; an included certificate does not guarantee calibration in the current month.
No battery procedure is required for LX-190's mechanical operation. You still need the correct attachment and the component's torque value. The portable tool does not supply a bicycle-specific service manual or electronic torque display.
12 months standard; 24 months when you register online within 90 days of purchase. Commercial defect coverage stays at 12 months; industrial use is excluded.
Lower the sliding collar, put the body scale at 14 Nm with micrometer zero aligned, then rotate the handle to add 1.0 Nm using five 0.2 Nm steps. Raise the collar to hold the 15 Nm setting.
Stop if the LX-190 collar cannot hold the selected setting. Lexivon does not offer repair services, but can assess other assistance options for a failed tool. Leave it intact and contact them; replacement depends on the circumstances of the case.
No. Lexivon advises against reassembly because it cannot guarantee proper operation afterward. Stop using the wrench, retain the loose parts and contact Lexivon for assessment before applying torque again.
Leave LX-190 at 2 Nm on the main scale and zero on the micrometer. This relieves excess spring tension for storage. Do not treat the Nm scale as permission to wind to zero or below 2 Nm.
Wipe LX-190 with a clean, dry, lint-free cloth. Do not immerse it in liquid cleaner, which can harm internal parts. After long non-use, run several low-setting operations before returning to a bicycle job.
LX-190 warranty excludes recalibration, normal wear, misuse, modifications and non-original parts. Coverage concerns defects in materials or workmanship; a travel disassembly or a need for periodic calibration is not an automatic defect claim.
