Birzman Frame gauge - Black

With the frame control method, it can be quickly and conveniently checked whether the seat tube, chainstays, and dropouts are aligned. If this is not the case, it can be the cause of shifting problems or the bike not running true to track.

• easy handling
• fits all common frame sizes and types
• thanks to the wider spacing between the dropouts, also suitable for e-bikes with hub motors and/or fat bikes (up to 197 mm spacing between the dropouts)
