Park Tool SG-8 Cutting guide for carbon tubes

Specially designed to accommodate wider, carbon specific saw blades, the SG-8 Threadless Saw Guide ensures a straight, clean cut on 1" (25.4mm), 1-1/8" (28.6mm) and 1-1/4" (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.
