Wheel truing stand Profi Unior 1689 2.1

A wheel truing stand for truing rims and checking lateral runout.

Features

• The caliper geometry allows simultaneous lateral control for accurate rim truing.
• The position of the upright arms can be adjusted with the upright adjustment knob to fit the axle width.
• The caliper arm position can be adjusted to fit the wheel radius, and the distance between the caliper tips can be adjusted to fit the rim width.
• The caliper arm is spring-loaded, and the calipers can be quickly pulled away. When a new wheel is inserted, they automatically return to the set position, allowing faster work with several wheels of the same size.
• The strong base provides high precision. Longer, redesigned upright arms offer increased clearance and truing accuracy.
• Wide calipers provide greater wheel clearance.
• Supports through-axle hubs up to 197 mm wide with adapters. Maximum arm opening without adapters is 230 mm.
• New spring-loaded bearings on the upright arm axle adjuster improve precision and reduce the frequency of calibration.
• Composite caliper tips prevent scratching the rim and are designed to make radial truing easier.
• Precision threads and springs ensure smooth operation.
• There are 8 mm bench-mounting holes on the underside of the base, with 268 mm between centres.
• All-black design.
• Includes conical magnetic through-axle adapters, one size fits all (12, 15 and 20). The adapters can be attached anywhere on the base and secured to the upright arms with a bolt for a more permanent setup.
• Includes white high-gloss stickers for the base and caliper arm to improve background contrast. The stickers are not pre-applied.

Compatibility

• Accepts wheels up to 32″ with the tyre installed.
• Supports solid, quick-release and through-axle hubs.
• Through-axle hubs are supported using the adapters included with the truing stand.
• One pair of through-axle adapters supports all through-axle sizes.
