Park Tool SG-7.2 Oversized Adjustable Sawguide

Need to cut down an aero seat tube, or some other weird shaped, non-round tube? Look no further!

Who's this for: Riders needing to cut tubes that aren't round, and need them nice and precise.

Tube compatibility: This will work on round tubes from 27mm to 45mm diameter. It will also work for any strange shaped tubes up to 70mm, such as an aero seat tube on a road bike.

Hacksaw compatibility: This has two guide slots for both standard hacksaws, and carbon specific blades.

Pros: Great for cutting odd shaped tubes. Compatible with both hacksaw blade styles.

Cons: Won't go small enough to clamp around a handlebar.
