Torque specs
Typical working ranges for the fasteners on a bike. The figure printed on the part always wins — this is what to use when there is nothing printed.
These are generic trade figures, not manufacturer specifications. Carbon components fail suddenly and without warning when overtightened, and a torque wrench that has never been calibrated is a confident way to be wrong.
Cockpit
- Stem steerer clamp bolts5.0–7.0Nm
- Stem faceplate bolts5.0–7.0Nm
- Headset top capBy feel, not to a figure
Not a torque setting. Tighten only until the bearing play disappears, then clamp the stem — the top cap carries no load once the stem is tight.
- Brake and shift lever clamps6.0–8.0Nm
- Bar end plugs1.0–2.0Nm
Seatpost and saddle
- Seatpost clamp5.0–7.0Nm
- Saddle rail clamp, single bolt12.0–20.0Nm
- Saddle rail clamp, twin bolt5.0–8.0Nm
Drivetrain
- Bottom bracket cups, threaded35.0–50.0Nm
- Cassette lockring30.0–50.0Nm
- Pedals into cranks35.0–40.0Nm
- Chainring bolts8.0–12.0Nm
- Rear derailleur mounting bolt8.0–10.0Nm
- Front derailleur clamp5.0–7.0Nm
- Derailleur cable anchor bolt5.0–7.0Nm
- Crank arm pinch bolts12.0–15.0Nm
Brakes
- Disc caliper mounting bolts6.0–10.0Nm
- Disc rotor, six bolt2.0–4.0Nm
- Disc rotor, centre lock ring40.0Nm
- Hydraulic hose fittings5.0–7.0Nm
- Rim brake mounting bolt8.0–10.0Nm
Wheels
- Thru axle10.0–15.0Nm
- Quick release skewerBy feel, not to a figure
Closed by hand. The lever should need firm pressure through the last half of its travel and leave a mark on your palm.
- Spoke nipplesBy feel, not to a figure
Set by spoke tension, not torque. Use the wheel tension tool.
Frame fittings
- Bottle cage bolts3.0–5.0Nm
- Derailleur hanger bolts4.0–6.0Nm
- Rack and mudguard eyelets3.0–5.0Nm
