Pro Shop Clamp

The clamp is the part of the stand a mechanic interacts with hundreds of times a day, so a clamp that saves a few seconds per bike swap pays itself back across a season. The Pro Shop Clamp does the saving on three details: a brass pressure handle that dials in tube grip without overtightening, a quick-release button that drops the jaw open without losing the pressure setting, and a 70 mm jaw height that's 25 mm shorter than a traditional cam clamp.

The 25 mm height difference is the spec that matters most often. Small road frames and any bike with a dropper post leave less seatpost exposed than the traditional cam clamp was originally sized for. The Pro Shop Clamp clears the dropper stanchion area on full-suspension bikes and gets a secure grip on the available seatpost on a small road frame, both of which the older cam clamp can struggle with.

Compatibility

The Pro Shop Clamp drops onto the column of every freestanding shop stand in our line (1693B Single Arm Pro, 1693C Double Arm Pro, the floor-mount variant) and on the BikeGator+ portable family. The mounting collar is shared across the catalog; the upgrade from a cam clamp to the Pro Shop Clamp is a swap, not a stand replacement.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The Pro Shop Clamp's brass handle is the kind of small material choice that separates a workshop tool from a consumer tool; brass holds pressure without thread-galling under repeated cycles and feels right in the hand on the thousandth bike of the season. The 70 mm height was set after mechanics flagged the older cam clamp's clearance on dropper posts and small road frames.

Pro tip from our mechanics

The Pro Shop Clamp is the fastest clamp in our line for high-throughput shops; the Master Shop Clamp is the more rigid clamp for shops running heavy e-bikes. The choice is real, and the right answer depends on your bike mix. A side-by-side comparison of the two clamps and how each plays with the different stand bodies: How to choose a bike repair stand →
