Thanks to all who responded. Much appreciated. I thought I was correct, but wanted to make sure.

I currently have a bike with a triple (yeah, I know ) on the front at 30-40-50 and a 12-27 on the back.

I'm considering getting a new bike with a 50-34 chain ring and a 11-34 cassette. I'm not in the best shape, but getting there. I wanted to make sure I wasn't loosing anything on the low end. Looks like I will have a lower low-end and a higher-high end, but just slightly.

Thanks again.
Glenn
