Once again, thanks for the input.

I've seen the Sheldon Brown (RIP) postings and they have been very helpful for me.

As for getting just an 11T cog, I prob'ly need 6th gear (13T), as well (Chain needs replacing, too). And from the little I looked (or rather, found), 2 cogs will prob'ly cost me as much as a whole new cassette. Which leads me to.....

I was doing some more research and discovered an HG-30 7 sp, 11-28T cassette with the same steps as my current cassette (No muss, no fuss). And the price was almost 1/2 that of going thru Performance Bike for the same cassette, so I'm ordering up 2!!! Funny part? It's at Walmart (and no shipping if I pick it up at the store Here's the link (if anyone else is interested....they also have an HG-50 8 sp for the same price): http://www.walmart.com/ip/Shimano-Ca...-30-7/13012504

Looks like I've saved myself from having to adapt (to) an 8-sp cassette, for now (I expect the time is coming

Again, I appreciate the feedback.

Cheers...Steph
