The 1630/2A is the no-frills version of the Pro Spoke Wrench 1630/2P. Same 3.3 mm four-flat engagement, same hardened-steel construction, same nipple-protection geometry. What's missing is the plastic-dipped handle: the 1630/2A has a bare steel grip.
For a workshop bench, the dipped handle of the 1630/2P is the right call; for a saddlebag, a tool roll, or a touring kit, the 1630/2A's compact and lighter form is the right call. The bare-handle version weighs less, takes less space in the kit, and pairs naturally with the Pocket Wheel Truing Tool 1753/6 for trail-side and adventure-ride truing.
The four-flat engagement is what carries between both versions; it's the geometry that protects the nipple from rounding, and it stays the same whether the wrench has a dipped handle or a bare one. If the wrench you need is the one you can fit in a seatpack, the 1630/2A is the right choice.
Compatibility
- Nipple sizes: 3.3 mm internal spoke nipples (within tolerance for 3.23 mm nipples).
- Engagement: four-flat.
- Wheels: factory wheels, lower-spec rim builds, and any 3.3 mm spoke-nipple setup.
- Companion: Pocket Wheel Truing Tool 1753/6 for trail-side use; the dipped-handle 1630/2P 3.3mm for bench work.
Specs
- Working size: 3.3 mm, four-flat engagement.
- Bare-steel handle (no plastic dip).
- Compact form factor for tool rolls, seatpacks, and touring kits.
Built in Zreče, Slovenia
Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The 1630/2A is the lightweight cousin of the bench-grade 1630/2P; same hardened steel, same engagement geometry, smaller pack space. A wheelbuilder's saddlebag spoke wrench should be the same engagement-quality as the bench wrench (otherwise it'll round a nipple at the worst possible time); the 1630/2A is the Unior answer.
Pro tip from our mechanics
Keep the bare-handle wrench in the pack, not in the parts drawer. A spoke wrench in a saddlebag is the wrench that's there when the wheel goes out of true on a ride; a spoke wrench in the bench drawer is a wrench that didn't come on the ride. The 1630/2A is small enough to live in the pack permanently; set it next to the Pocket Wheel Truing Tool and forget it until you need it.
