Unior 1689 Pro Truing Stand accepts wheels from 16 to 29 inch with or without tire and accept hubs up to 197 mm width. It can be bench-mounted or vise-held.
Designed for bike mechanics enthusiasts and professional workshops, the Professional Wheel Truing Stand 1689 has been completely redesigned to offer greater precision, robustness, and ease of use. Thanks to a reinforced base, extended arms, and technical improvements on threads, springs, and bearings, it ensures an even smoother and more reliable truing process.
The new magnetic conical adapters for thru-axles fit all standard sizes (12, 15, and 20 mm) and can be magnetically attached anywhere on the base for convenient storage. For enhanced readability, high-gloss white stickers are included to improve visual contrast when aligning the wheel.
