8-piece Combination Speed-Wrench Set

An open-end wrench that ratchets is the kind of design choice that sounds too good to be true until you use one. Unior's IBEX wrench profile turns a conventional open-end into a ratcheting tool; slide the wrench over the fastener, turn, and the jaw engages on the forward stroke and slips on the return without lifting off the fastener. The result is the access advantages of an open-end with the cycle speed of a ratchet.

The 129/1CT set covers eight sizes from 8 to 22 mm, in a polyester tool roll with a velcro closure.

What's in the set

Eight IBEX combination wrenches:

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

The 15 mm is the pedal-axle size; the 10–13 mm range covers cable-stop adjusters and small lock nuts; the 17–22 mm range covers older crank-arm bolts, BB lockrings, and larger headset components.

How the IBEX profile works

The jaw geometry isn't a standard open-end. The contact surfaces are angled slightly so they cam against the fastener on the forward stroke (the direction of torque) and slip on the return stroke. You can ratchet through a long cycle without lifting the wrench off the fastener; useful for fasteners deep in a recess where lifting the wrench would mean re-positioning it from scratch each cycle.

The video at the top of the listing shows the mechanism in action. The action is subtle but unmistakable once you've felt it; the wrench advances on every forward turn even though the geometry looks like a normal open-end.

Where it earns its space in the bike shop

• Cable-stop adjuster nuts in tight spaces where lifting a wrench is awkward.
• Old-style brake bosses with small lock nuts behind the boss.
• Long-cycle work on stuck fasteners where a normal open-end would require dozens of re-positions.
• Travel/portable mechanic work where carrying a separate ratchet handle isn't practical.

When a standard combination wrench is the better tool

For high-torque work, a 12-point or 6-point box-end gives more torque capacity than the IBEX open-end can deliver. The IBEX is faster for cycle work; standard combination wrenches are better for the final torque application or for breaking stuck fasteners loose. Many shops own both.

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 IBEX profile is a Unior original, developed and refined inside the Zreče workshop rather than licensed from a third-party manufacturer. The cam-action jaw geometry only works if the manufacturing tolerances hold across the full production run; a sloppy jaw won't catch on the forward stroke, and a too-tight jaw won't release on the return. The wrench works because the geometry is held to spec, not because a clever idea overcame imprecise execution.

Pro tip from our mechanics

Once you've used an IBEX wrench on a fastener in a tight workspace, the ergonomics of a normal open-end will feel like a step backward. For the framework on combination wrench types: Combination wrenches in the bike shop →.
