I have a Quintana Roo TeQuila and today I noticed that it looks like I have some spacers under the stem. I am guessing that I actually have a 1 1/8" tube and it is just he spacers that make it indicate larger when I measured it. I will check to verify but I thank that is it. Thanks for all of your help. It has been a while since I have had a road bike and some things have changed from the old 10 speeds of the 70/80's.
