I find that extremely hard to believe. I have also heard that a certain aero seatpost could add 2 mph. And certain wheels 4 and the right handlbars.....pretty soon I should be able to ride the local TT with an average close to 37.thr0ttles said:an old issue of bicycling did a full study on the size and shape of brake pad fins and determined their impact on the aerodynamics of a bicycle. from what i remember, the fins had a positive impact and accounted for an extra 1.2 mph in ideal conditions.
the tabs that are being refered to, are for wheel changes. If that's how you set the toe in on your pads, you must have arms like barry bonds.kenyonCycleist said:those 'fins' as you call them have nothing to do with aerodynamics or guiding in the wheel, They are for 'toeing' in the brake pads, there is a tool made to fit over that fin-like tab that acts as a lever to gently bend the brake arm to contact the rim at an angle (i.e. toeing the pad)
Alright, you got me on that one, but you gotta admit, there is not shortage of ridiculous (but serious) claims out there in the cycling press.thr0ttles said:finally...someone with a sense of humor that hasn't been deadened by too much time in the saddle.
The molded plastic fins, like in an Ultegra brake pad, are wheel guides. They are swooped and wing-looking to make them look cool. Not even Shimano claims any aerodynamic reasons.Kaboom said:I am ideed asking about the shoe. excuse me if i wasnt clear.
Well, some one-piece pads have the wheel guide fin molded in, but the other fin is a flared extension of the pad towards the back of the bike. These are common on Ritchey cartridge pads and to a lesser extent on Kool-Stop pads - the marketing text is that this acts as a 'squeegee' to remove water and debris from the rim just before the 'meat' of the pad squeezes the rim, thus improving braking.Kaboom said:I am ideed asking about the shoe. excuse me if i wasnt clear.
