Unior has redesigned many of the features of the 1689 professional truing stand. The base has been reinforced for greater accuracy, including adapters for tapered thru axles (12, 15 and 20mm) which can be stored anywhere on the base. The arms have been lengthened to better accommodate the 29" wheels and the calipers enlarged accordingly. The threads, springs and bearings have all been revised for smoother operation. Gloss white decals for the base and arm are also included grip to improve background contrast, making it easier to use.
