How long can you expect a set of Brunswick GC3 rails to last? I imagine they eventually lose their elasticity--what's a good rule of thumb for when to replace them? Thanks
I've replaced them in less then 3 years from new and others have lasted 15 years or more. I guess it's according to which batch they came from. Most times you'll see some hardening within 5-8 years. I never replace just one, as soon as one starts to go the others will be following shortly thereafter.
