    Can anyone tell me the weight of a 12-25 Ultegra 9 or 10 sp vs a 12-27 of the same?

    Try this site:

    http://weightweenies.starbike.com/listings.php

    It lists the 12-25 9-speed at 220g and the 12-27 9-speed at 223g.

    You're joking, right? You right on the UCI's weight limit or something? I'd guess that it's less than 20g difference.

    Please understand that the following is meant only to show my complete opposite view by use of humor. If a person considers a gram or two important, then I fully support their right to be concerned about it...

    But I have to wonder, in a few years when people have gotten past the obsession with a few grams of bike weight, and move on to being obsessed by milligrams

    The Top Five questions about how to lower any bicycles weight...

    5) Which lubricant weighs the least when properly applied?

    4) How few strands do I really need in a brake cable?

    3) Is silicone lighter than wax to protect my frame?

    2) Which protectant sheds that heavy dust better during my ride?

    [Insert drum roll here]

    1) I need a fast acting but temporary laxative to lose that extra little bit before the race. What do you suggest?

    I just weighed a 12x27 Ultegra 9-speed cassette in my parts box and got 214 grams w/o the lockring with the lockring adding 13 grams for a total of 227 grams. apparently weightweenies mislead you And, yes my scale, a lab quality Ohaus, is accurate.

    To answer a question you didn't ask, a 13x25 HG-70 (105 level) 9-speed cassette weighs 237 grams w/o the lockring and the lockring adds 13 grams. To compensate for that massive weight penalty, you acquire a 16T cog.

    I'm not concerned at all, just curious. I have upgraded my wheels, a savings of 260gr.
    I am upgrading my saddle, for a savings of 50gr, and my pedals for a savings of 85 gr, for a total of 395gr. I switched from a 12-27 to a 12-25 and was just curious as to what it was, I know it would be miniscule, I'm just trying to get an accurate total.
