The Park Tool CT-5 performs like a shop-quality bicycle chain tool, in a lightweight (77g) 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 SRAM AXS & Shimano XTR 12-Speed Chains. The integrated shelf is useful for loosening tight links on older style chains. The fine thread, special V-shaped handle, and super strong replaceable pin (part # CTP) make chain replacement a breeze.

*NOTE: The CT-5 will not peen Campagnolo 11-speed chain rivets (see CT-4.3 or CT-6.3)
