What torque setting should I use for my carbon handlebars?

Check your handlebar's spec — most carbon bars specify 4-6Nm per bolt. The spec is typically engraved or printed on the stem faceplate or bar clamp area. If in doubt, 5Nm is a safe starting point for most 31.8mm carbon bars.

Can I use this with Torx (star) bits or only hex keys?

Yes — the 1/4" square drive accepts any standard 1/4" bit, including hex (Allen), Torx (T-series), and Phillips bits. This makes it compatible with the full range of modern bicycle fasteners.

How do I know if my torque wrench needs recalibration?

Use a known reference — tighten a fastener to exactly 5Nm on another reliable wrench, then check with this one. If the click fires at a different angle or force, send it for recalibration. Birzman-authorised service centres can recalibrate to ±4% tolerance.
