Long 8pcs Combination Wrench Set

Long-handle combination wrenches are the right answer when the job calls for leverage. A stuck pedal axle, a high-torque BB lockring that needs to break loose, a crank-arm bolt that's seated harder than expected; these are the cases where the extra inch or two of handle length is the difference between cracking the fastener loose and stripping it.

The 120/1CT set covers eight sizes from 8 to 22 mm in the longer form, in a polyester tool roll. Twelve-point box ends across the set.

What's in the set

Eight combination wrenches in long-handle form:

• 8 mm
• 10 mm
• 11 mm
• 13 mm
• 15 mm
• 17 mm
• 19 mm
• 22 mm

The same size range as the short-handle set; only the handle length differs.

Why length matters

Length on a combination wrench is the lever arm. Double the length and you double the torque at the same hand force. The math is unforgiving; a 200 mm wrench applying 100 N of hand force delivers 20 Nm; a 300 mm wrench at the same hand force delivers 30 Nm. For fasteners that need real torque to break loose or seat to spec, length is the cheapest mechanical advantage there is.

The trade-off is geometry: a long wrench needs clearance to swing. In tight workspaces, the short-handle set is the right tool. Most shops own both formats.

Where the long-handle earns its space

• Pedal axles. 15 mm flats, often stuck after a season; the long handle delivers the torque to break them loose without rounding the flats.
• BB lockrings. Where the lockring has flats rather than an internal-toothed socket interface.
• Crank-arm bolts (older designs). External 14 or 17 mm hex heads on pre-Hollowtech crank designs.
• Headset adjustment nuts. Larger 22 mm headsets on older builds.
• Anywhere the working space is open and the fastener is reluctant.

The 12-point box-end

Same trade-off as the short-handle set: 12-point engages at corners (faster fit, twelve angular positions per rotation) but can round alloy fasteners under high torque. For very high-torque alloy work (a stuck crank-arm bolt on a soft-alloy crank, for example), a 6-point socket driven by a 1/2-drive ratchet is the safer tool. For most bike-shop fastener work, the 12-point combination wrench is fine.

Made in Slovenia, since 1919

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The handle length on each wrench is sized to the torque range its size will see in service; the 22 mm gets more handle than the 8 mm, because the 22 mm is what's used on high-torque fasteners that need the leverage. That's a quiet design choice; most combination wrench sets scale handle length linearly with jaw size, which gives you too much handle on the small sizes and not enough on the big ones.

Pro tip from our mechanics

The 15 mm in this set is the one that earns its keep on pedal day. Once a year, when a customer brings in a bike with pedals that haven't been off in two seasons, the long-handle 15 mm is what gets the pedal moving without rounding the flats.
