gasket

Hi guys, Apologies for those sick of SBL posts but I’ve read all threads and can’t see this specific information. I’ve bought all the materials as per the excellent post by doublebubble. I cocked up when ordering my neoprene as bought one specifically for gaskets but it was solid rubber 😫...

I am using my SBLs since the last 10 years at the same place. I see that TomTom are selling gaskets and I wonder if it is a good idea to renew the gaskets after a long period of time? Arye
