somehow your image didn't show up...

so is there a left and right lever? i'm about to put an order in.

also what tools are required? looks like i'd need some special tool to remove the bolt at the pivot.

can you see it now (attached on mtbr)?

Greg answered your other question it looks like.

Here's a German test with Bianco's / Code's / etc : http://www.sharebigfile.com/file/107041/07dhbrakes-pdf.html

I would also like to point out that we also have specific models made for specific applications:

Oro K18: Entry level XC/AM
Oro K24: Mid level XC/AM
Oro Bianco: DH/AM/FR
Oro Puro: High end XC/AM Race.

Hey Chris, is there really a difference between the Bianco and K24/Puro? I just recently got the Puros which are excellent by the way. Was told by my LBS that the Bianco is just a pimped up version of the K24. Care to elaborate the difference? Thanks! ;)

All the Formula brakes use the same master cylinder and caliper body. Where they differ is lever material, braided lines, lever length, hardware (Ti or Aluminum), and pads (sintered v. organic) and the color.

Biancos use a one finger lever, sindered pads, have some TI bolts, and use braided lines aimed at DH/FR.

Chris might be able to expound more but thats it as far as I know.

Basically all of these brakes are the same, with tweaks to get them to fit a range of riding. They aren't truly application specific.

I'm not sure i'd go that far to say that. Isn't brake compound, rotor size, and disc hose material making it more application specific?

Do you really need to dictate an XC/DH/FR powered brake by the number of pistons?

Shimano does the exact same thing. XT is the same as Saints just a different body color and utiling varying rotor sizes and those brakes are awesome for DH/FR. They dropped their 4 piston design for it.

Hope Moto FR for example is a two piston brake, The Moto FR offers a 25% increase in power compared to the MonoM4(4 piston) or Mono6(6 piston) with the same disc diameter.

The 4 pott xt still feels like it has more power and more controlled power while hauling yourself down from high speed stuff.

The rotor surface area is like twice as wide on the Moto.

Yea I have a set of the 4 pots and they do work great and trouble free. While they do feel great hauling down from high speed, i don't think the newer design Saint/XT is far behind as far as braking or overall power.

Yes the rotor is bigger, but its still two piston was the main point.

There is a lot in this post that makes me chuckle. Some of it falls into the "state the obvious" category. Some of it falls into the "lack of understanding the usage of multiple pistons" category.

So just a moment, is the Bianco lever really only for one finger? I mainly one finger brake on my Mono6s but am looking at building up a 30lb-ish All mountain bike that would be used for everything from steep trails to xc races, which Formula brake would be the best choice?

I just came off a pair of XT 4-pots (with Dangerboy levers and Goodridge lines) and I must say they are better in terms of stopping power and modulation as compared to the XT (conventional 2piston) which I was previously using (with Goodridge lines as well for fair comparison).

The Puro provides a better feel in terms of modulation and the braided lines look wicked. Still need some time to break-in the brakes as the stopping power isn't there yet. But I should be getting there soon as the feel on my 2nd ride was much better and it provided excellent control in the singletrack. Only thing I miss is my Dangerboy levers from my previous setup. Darn ...

The Bianco lever was developed based on input from the Honda/G-Cross team.. They wanted a narrower lever for one finger braking. If you're thinking you might be better served by the wider lever on the K24, you can always buy the sintered pads when you wear through the stock organic pads, and power wise you will have the same brake. We get a lot of comments about the K24 levers being very comfortable - the Bianco is new enough that we haven't gotten a lot of feedback in the US. Minnaar likes it, though!

I personally use one finger with the Puros on my Nomad (32 lbs give or take), and it works great for me.

Best regards,
Greg

Well I probably only ever one-finger brake, so the Bianco may be the best choice (not to mention it has an awesome finish!), but if I were to get the Bianco and then later decide I want the wider lever, could I purchase some extra levers and swap them? The lower cost of the K24 is still attractive though...
Thanks for the response!

Edit: just looked back in the thread and I think my lever swapping question has been answered.

well myK24's just arrived yesterday, so fitted them and went out for a pretty hilly 20 mile ride. These brakes are awesome straight out of the box!!

Even without bedding in they have great power and modulation. I bedded them in during the ride, and now they are better than the Hope minis and Juicy 7's that i have tried. Set up was simple (my hoses are a teeny bit long, but they'll do - i dont fancy cutting them as i know i'll make a mess of it, and i dont really want to book my bike in at the shop as i'll lose riding time :))

I have one little query though for other users (and Greg from Formula if he reads this!!):

When i first put the front on and tried it in my street, there was a tiny 'click' each time i applied the front brake while moving. I checked caliper and post mount bolts and all are tight + alignment seems good. I put a bit of copper grease on the back of the pads, and the 'click' went, but i have a very slight buzz now when braking (its not loud at all, and no vibration felt). The noise doesnt bother me, just wondering what it could be? Is it some vibration of the pads, or something more serious?? All the bolts are torqued up correctly, + loctited where required.

Anyway, i would defintalely reccommend these brakes if the original poster hasnt ordered theirs yet!!

what is ur set up (fork and bar rise), and how long is ur front brake hose (100 or 85cm)?
I just ordered a 100cm, and i'm thinking the 85cm might be long enough (measuring my current hose)........ but there's been a report of the 85cm being too short on a similarly equipped bike.

My brake hose is 85cm,
Forks are Fox Float 100mm
Vertical distance from Dropout height to bars 68cm (shock completely unloaded)
Lever clamp is 19cm from centre of bar
Stem length is 90mm

ideally my hose could be a bit shorter, but its ok as it is,just gives a slightly larger curve of hose from the bar to the hose guide on fork leg.

HTH if you want any other measurements let me know. But it will be tomorrow before i go to garage again as i've just opened another beer :D

Hi guys,

Eldiablo: The click you remedied was most likely the pads/pad spring breaking in or the pad shifting slightly in the caliper. It probably would have gone away by itself after a few break-in rides. Your solution should be OK as long as you used only a very small amount of the copper grease.
The very faint buzzing/whirring you hear is not uncommon with our brakes and it can be attributed to the shape of our rotors and pads. Nothing at all to be alarmed about...it sounds like they are working correctly.

Re: other questions about hose lengths:
Ft: We have found that the 850 front length is long enough to fit most single crown forks with 160mm of travel or less. If you are running a 160mm fork and you have XL bike, if your frame has a particularly large headtube, if your using 20mm+ of HS spacers, or a high rise bar you should probably move up to the 1000mm.
Rr: The 1500mm rear fits most bikes with the following exceptions: Large or XL 29er, XL 26" which have particularly long cable routing or very long/high rise stems or bars. Large or XL DH/FR bikes which are using extra wide bars.

If in doubt, get the longer length! All of our brakes come with a new fitting kit if you need to shorten your hose.

I hope that answers all the questions.

Cheers,

Chris Costello

Short answer is no. Only Glycol based DOT fluids, not silicone.

5.1 is NOT silicone. DOT5 is silicone based. Since silicone came out before 5.1, it was given the DOT5 designation, thus the break in compatibility going from 4-5.1. Please do a websearch to verify this fact.

DOT 4 is compatible with 5.1. I can also scan some of the instructions from my autorepair manuals and my Hope manuals that speak of this compatibility as well.
