Have you ever come down a 4 mile down hill .
I will stick with the daul pivot.
Screw the weight saving .
You got the cash .“lightest brakes …yes even lighter than zero gravity, well maby those carbon ones that cost $700 a pair are lighter)”
Try them out.
They ain’t but $ 100.
Dual pivots are easier to center and keep centered. Disadvantage is uneven braking when pads wear - one arm will start to contact the rim higher and higher and the other, lower and lower.
They are about the same weight at the 0G-SS model, but not nearly as light as the ti model.
I would personally be happy to take a 100g or so penalty in weight for the added stopping power of a dual pivot system. The weight isn’t rotating and their isn’t likely much aero difference, so in a TT sense, it’s a negligible piece of hardware.
currently using Brew light brakes (lightest brakes …yes even lighter than zero gravity, well maby those carbon ones that cost $700 a pair are lighter)
can any on tell me about the actual benefit sof upgrading to dual pivot.
break force gain, stopping distance shorten…etc
real data not just “they feel…”
thanks
Personally, I find a bigger difference in brake pads than I do in single vs. dual pivot braking.
On my road bike, I use Cane Creek 200SLs with Koolstop dual compound pads. They stop every bit as good (or better) as the dual pivot Cervelo branded brakes on my TT rig (with generic black pads). The Koolstops on the Cane Creeks provide more than enough stopping power.
IMHO, I’m not sure why most people think you need TONS of braking power on your front wheel…the LAST thing I want to do is to lock up my front wheel. Bad things happen when it does.
i’m like you, until very recently, i have used single pivot campy (classic super record) w/ special pads and classic single pivot dura ace w/ standard pads for simplicity and wt. savings. but then i tried a mechanical (avid) disc-equipped road bike.
wow.
that converted me to get one, as i like to ride in wet conditions. and front braking power can make a huge difference in straight-line stopping distance. believe me.
then i recently went to DA-10 caliper brakes on my race bike, a light and elegant dual pivot design with adjustable camber pads and a much better pad compound. it is pretty clear that these do work better with a lot less lever pressure. they are so good, i would almost call them ‘grabby’, even on AL rims. and the DA-10 dual pivots are very light and priced reasonably. try 'em, i think you will notice the performance improvement.
Just get a cheap pair of dual pivots and run the front. This gives the best mix of braking power and weight. This is how some sets of Campy brakes come.
Yeah, there IS a difference. You have to draw the line somewhere though between price and performance (not that I did - I use the Zero G ti brakes
I actually like the DA 10 brakes BETTER than my Zero Gs overall (based on modulation, ease of use/adjustability, etc. The Zero Gs are super strong and with good modulation, but very hard to adjust “just right”. I swap wheels a lot between 3 and have to adjust every time as I’m super anal about braking feel/rub/etc. and I train in some hills and use them until smoking sometimes!. The DA 10 calipers make it super easy with the changes.
Not only is the stopping power greater for most of the dual pivot brake calipers vs single pivot designs…many times the modulation is better. I’ll take the power and modulation of the Dura Ace calipers over any other design I’ve tried.
Sorry, no hard data. I love the way dual pivots can be adjusted and how they stay adjusted. Also, the modulation on a cheap pair of Shimano dual pivots seems (sorry - best I can do) much better than the best single pivots I have ever used.
Yeah, single pivot are fine for the rear, or front and rear on a TT bike. Just upgrade the brake pads. An every day bike or a road bike should go with the dual pivots.
dual pivot stop way better, but in my experience all that happens is I have to squeeze harder with the single-pivots - the actual stopping distance is much the same. Adjusting the duals is also a lot easier. I wouldn’t put single-pivots on any new bike, but I’m still using them on my road bike (used to be race bike).
I don’t think dual pivots have more stopping power, they maybe have a higher ratio of stopping power to lever effort.
For a Tri/TT bike, single pivots work fine. They can slow the bike down for corners, and if it’s a panic stop situation, you naturally pull the lever harder.
IMHO, I’m not sure why most people think you need TONS of braking power on your front wheel…the LAST thing I want to do is to lock up my front wheel. Bad things happen when it does.
I’m with you on this. I got a pair of 200SLs from another STer and they have been great. Plenty of braking force when adjusted properly, and they are a lot easier to modulate than the dual pivots I had on there (Ultegra I think). The pads are key though…

I don’t think I’ve ever locked up the front wheel with dual pivots, under any conditions.
