with that money you could buy an actual motorbike! And have proper fun :D

Thanks for pushing me over there. Somehow I already had the spreadsheet with brake data from that thread in my google-docs.

Anyway.. I've added a bit of data I gathered from mtb-news forum and the Hayes Support: The Dominion A4 comes out almost as strong (on paper) as the Direttissima which (I guess) is regarded one of the strongest brakes, only bettered by Trickstuffs own Maxima Brake.

The Cura 4 is a bit less powerful... Anyway.. when looking at the overall system leverage (hydraulic and mechanic) your input would be multiplied about 39 times with the Direttissima and A4, 36 times with the Cura 4. I'm really looking forward to finding out if these paper-facts will translate into your comparison.

What sets the Dominion apart from the other brakes and explains the light lever feel is: The A4 generates by far the highest hydraulic leverage whereas Trickstuff and Formula achieve their braking power by using a relatively high mechanic leverage. That could explain the super light action and good modulation.

BTW: V4 comes out really week: Your input will only be multiplied almost 30 times.

Code is not much better (due to rather small braking calipers, factor 32.7

Combine the V4 caliber with a Code OR Dominion Lever and you'd put that brake on par with the pure A4 or Direttissima brake.

I don't know if anybody is interested in this... but I am :D

I mean, in the end I might try and pair some CODE RSC levers with Hope V4 calipers... but who knows.

Did you ever measure things while tearing down? What's the calipers diameter, can you give information about the hydraulic leverage generated with the lever? What's the size of the master cylinder?

The rest is trickery physics.. but calculatable :D

Damn I really dig these brakes. I'd like to really like the clumsy looks though. That housing is just plain ugly.

So now I will wait for your Cura 4 review. I really need to decide how to upgrade over those quickly overchallenged Guide-Rs mounted on my bike. Bringing 100kg and too much speed to every corner the guides need to go before it's drying up :D

yeah, what Bagheera said.

I like to spin between 80-90 rpm while seated and have developed a habit to stand up when the cadence drops. Maybe it's my knee-issues that force me to do this, but I really shift around a LOT while climbing.

Made my day! That's the last tick in these direction I needed as this annoys me a lot on the mallets. Since I switched from XC-shoes to more sturdy ION-Rascals I have to move the cleats too far inside to my liking.

Thank you!

and that's my point living in the black forest. You can easily find a 1000m vertical ascend with an average of 10% incline or more. (So 8 to 10km) To the point where pushing seems more efficient than pedaling on a 30-50 ratio.

Yeah.. and that's a totally valid point. You're not even hiding your point of taking the data to use towards your own agenda. Still wanted to point that our.. wasn't sure if I was sounding like a roadi though, emphasizing on  pedalling frequency and such :D

About the wider Q-Factor, first off I was thinking about replacing the axis in my mallet-e pedals with the long spindle versions.

So Dougcan uses the upper half of his cassette most. But than, as he shifts so often, isn't that due to the small spacing, that he can always pedal efficient in a (to him) nice frequency?

To me Eagle was the greatest thing. I'm mostly on the 10,12 and 14 teeth rings to commute to the trail, on the steepest parts of the access gravel roads I am using even the 50tooth pie platter quite a lot. (Using a 30t front ring)

All the in between rings are in use, too. I don't know if my lazy ass and weak limbs are the limitation here though.

But I do understand. I guess one could live with less rings, especially when we would be able to build stronger wheels. And when we do that we can talk about wider bottom brackets, too (like in the chromag article), and build way stronger rear triangles, wheels, chains into our bikes.

(sorry for the bad english, it's not my mother tongue)

Hey Andrew,

when will you follow up this and the Dominion's teardown with a longer review piece and maybe a sweet nice comparison on braking power and such?

I'm trying to decide between these two and the MT7 but I just cannot :D

drop 15 kilos and work on my FTP --- up it to 270-300 Watts (3 Watts per kg bodyweight) (driven by numbers, I am :-D )

Climb my nearest mountain (1000m altitude change) in under 75 minutes (currently 100minutes)

be able to do 10 Pullups, 50 Pushups, run 10km under 50minutes
