Overview
Is the Park Tool CT-5 Compact Chain Tool worth carrying?
The Park Tool CT-5 Compact Chain Tool is a pocket-sized chain breaker built for on-the-road and trail-side repairs. Despite its compact form factor, it handles the full range of modern chain widths from 5- through 12-speed, using the same hardened steel pin drive design that Park Tool builds into its full-size professional chain tools.
The folding handle keeps the CT-5 safe and snag-free in a jersey pocket, saddle bag, or handlebar pack until you need it. When a broken chain threatens to end your ride, this tool has the precision and build quality to push the pin cleanly and get you rolling again. It is small enough to forget you have it until the moment you need it most.

Good questions
Get to know Park Tool
There's more to Park Tool than this one product. Our Park Tool page has the full Park Tool lineup we carry and more about the brand.
Visit the Park Tool page →Does the CT-5 work on 12-speed chains?
Yes. The CT-5 is compatible with 5- through 12-speed chains, covering the full range of modern road, gravel, and mountain drivetrains.
Is the CT-5 small enough to fit in a jersey pocket?
Yes. The folding handle keeps the CT-5 compact and snag-free, making it easy to carry in a jersey pocket, saddle bag, or handlebar pack.
Can the CT-5 replace a full shop chain tool?
For field repairs, yes. For high-volume shop use or frequent chain replacement, a full-size bench tool like the Park Tool CT-3.3 or CT-6.3 is recommended for better leverage and durability under repeated use.
