I have had the same two cassettes for a long time. Both are Ultegra. 1 is a 12-28, and the other an 11-25. I mixed the 12 through 19 with the 21-23-25 to create a 12-25, which is perfect for the flat area around me, but used the 11-28 for Oceanside. Any issues doing this?
And how can I tell when it's time to replace a cassette? I over ran my last chain, but I don't know what to look for in tooth wear. Should I post a picture?
