Know before you buy
The CT-5 is officially rated for 9, 10, and 11-speed derailleur chains. While it may work on some 12-speed chains, it is not specifically engineered for the narrower tolerances of those systems.
Yes, the CT-5 features a replaceable pin. This allows you to maintain the tool's performance over time rather than replacing the entire unit when the pin eventually wears down.
The CT-5 is designed specifically for derailleur-style chains. It is not recommended for use on wider, single-speed, or BMX-specific chains, as the pin and cradle dimensions are optimized for thinner multi-speed systems.
While its compact size makes it perfect for a saddlebag or jersey pocket, the CT-5 is robust enough for regular home maintenance. However, if you perform frequent chain work, you might prefer a larger shop-grade tool with a longer handle for increased leverage.
The CT-5 includes a specific cradle position that allows you to apply pressure to a tight link. By carefully pushing the pin just enough to loosen the side plates, you can restore smooth movement to a stiff link.
