So it's raining and I'm doing inside maintenance. Pulled the rear wheel off the LeMond to check bearings, cog wear and such. I'm a little cornfuzzled. It looks to be a Campy cassette....13/26 but the Bontrager wheels came with the bike and it was originally Dura Ace.

Anyone know how to tell what splines are under the cassette w/o removing the cassette? I don't have a lock ring removal tool of a chain whip handy.

Second, the cogs look to be wearing....I don't seem to see anything larger than a 26 ring available, is that right?
