Park Tool, CT-5, Portable chain Tool

The CT-5 Chain Tool performs like a shop-quality tool, in a lightweight compact size that easily fits in a saddle bag or mobile mechanic's tool roll. The CT-5 removes and installs pins on all 5-to-12-speed derailleur chains, including newer SRAM® 12-speed designs. The integrated loosening shelf is useful for adjusting tight links on older style chains.
