The length is set by the gap between hooks once the joint is together; the sleeve is set by whether the machine is used on the road.\u003c\/p\u003e\u003cp\u003eThis is the short one with the sleeve — the combination most road builds end up needing somewhere.\u003c\/p\u003e\u003ch2\u003eChecking the Tension\u003c\/h2\u003e\u003cp\u003eFitted correctly a spring should be visibly extended and should return with a snap when pulled and released. One that lies almost straight in place is doing nothing but rattling; one stretched until the coils separate has been permanently deformed and will not pull the joint closed again.\u003c\/p\u003e\u003ch2\u003eReplacing Rather Than Reusing\u003c\/h2\u003e\u003cp\u003eSprings are consumables. A set that has been on a system through several seasons of heat cycling has lost tension whether it looks it or not, and at five euro each there is no argument for reusing them after a rebuild.\u003c\/p\u003e\u003ch2\u003eFitting\u003c\/h2\u003e\u003cp\u003eA proper spring hook, pulled rather than levered.
