along with sitting on the bike for fit... look at the actual measurements.. make sure that top tube is the same for the sequois and dolce...

i, too ride a dolce (2004 elite... so i have ultegra as the majority of my components.. i don't know why they stopped making then... dolce's with ultegra.. but i digress)

i would recommend getting... in addition to the bike that fits best.. the one that you LOVE... if you love it you will ride it more! if you are "settling" with the sequoia.. then don't get it... cuz even if you are happy with the bike.. you won't be truly "happy"....
