Thru-axle Adaptor for 1693R Pro Road Stand

Thru-axle road bikes and gravel bikes don't fit the original 1693R Pro Road Stand mount geometry, which was designed around the QR-skewer fork-end interface of the 2010s road bike. The 1693R.2 Thru-axle Adaptor is the bolt-on extension that takes the same Pro Road Stand and makes it the right stand for modern thru-axle road, gravel, cross-country, and TT bikes.

The adapter clamps over the support beam of the Pro Road Stand and grips the bike's thru-axle directly. The geometry presents the bike to the mechanic the same way the QR mount does: bottom-bracket-area support, five-axis adjustability for fit work, no clamp on a frame tube. The adapter is welded steel and sized to take meaningful working load without slipping or flexing under the mechanic's pry on a stuck axle or a tight headset.

A practical detail that matters once the adapter is in the shop: the adapter can live on the stand alongside the QR-skewer mount. Loosen the underside fixing bolt, slide the adapter out of the way; tighten when you need it back. Shops doing mixed-axle work (a vintage road bike on QR, the next bike a thru-axle gravel rig) don't have to choose at the start of the day which mount to fit; both ride the stand together.

• Coexists with the QR-skewer mount on the same stand; loosen the underside bolt to slide between configurations.

Specs

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The 1693R.2 is the kind of adapter that exists because the Pro Road Stand has held its design long enough that the bikes around it changed; the QR skewer used to be the road-bike interface, and now the thru-axle is. The adapter is what makes the stand still the right tool a decade after a fork-end standard shifted.

Pro tip from our mechanics

Most shops doing road work today see thru-axle as the default and QR-skewer as the exception, which means the 1693R.2 isn't really an accessory anymore; it's the working mount for most bikes. Order it with a new 1693R, 1693RP, or 1693RP1; for shops already running an older stand, it slides onto the beam without modification.
