Park Tool SG-8 Bicycle Saw Guide for Carbon Composite Forks Specially designed to accommodate wider, carbon specific saw blades, the SG-8 Threadless Saw Guide ensures a straight, clean cut on 1" (25.4mm), 1⅛" (28.6mm) and 1¼" (31.8mm) threadless fork steerer tubes. Also works great when cutting handlebars or other round tubes from 22mm to 33mm. Simply clamp the SG-8 onto the tube and cut, letting the SG-8 guide the hacksaw blade. The SG-8’s non scratching composite body incorporates steel threads and a steel reinforcing plate to withstand the rigors of heavy shop use. The SG-8 accommodates blades up to 2.5mm (3/32") wide. NOTE: SG-8 is intended for use with a carbon-specific diamond-type saw blade. For use of standard steel hacksaw blades, use the SG-6 or SG-7.2 Threadless Saw Guides.
