(Pete Cresswell) said:I just swapped my rear Avid mech out for a Shimano Deore XT V brake.
Weighed the V plus cable against the Avid plus cable plus rotor, found a diff of
110g - i.e. about 1.75 ounces.
One ounce = 28 grams.

rider IMHO.
I weigh more. :-P Lose 31 pounds and you've got the equivalent of a
bike that weighs 0 pounds.
Quoted message said:Is this typical? Seems like a lot of the disc brake setups I see on other bikes
look considerably lighter than that Avid mech...and there doesn't seem like much
room for lightening a V brake... Could it be a wash in some cases?
IMO, the whole point of disk brakes is to get the braking mechanism out
of the water, crud, and mud. Weight isn't as much as a factor as the
functionality.
Beating up on an easily replacable disk is better than ripping the hell
out of the sides of your aluminum rim with embedded junk in the pads
especially in the winter, riding through puddles and sand from the
sanding trucks and hearing that gawd-awful scraping sound on your Open Pros.
