Rotors and Brackets not included
Get everything you need!
Low Input - High Fidelity (LoFi)
Low effort system with predictable, progressive ramp up and a crisp bite point.
Loaded With Tech
Reduced Friction - A featherlight lever feel is acheived through a combination of an added glide ring on the piston and sealed ball bearings at the lever blade pivot
SRL - Our Stable Rate Link delivers a consistent lever ratio regardless of reach
Precise Engagement - Each Dominion is factory set to have the lowest dead stroke possible and a crisp bite point.
Built to last - Metal pistons are used to ensure that no matter the terrain or temperature your brake will continue to perform as it did on the first ride
Adjustable Reach - Adjust your lever reach with ease while on the trail thanks to an intuive adjustment knob design
Modal Resonance Cancellation (MRC)
FEA-optimized modal shapes of D-Series rotors are intentionally designed to oppose those of Semi-Met T106 and Sintered T100 pads, canceling out noise and vibration.
Hi, I would like to know which pads is included in the box? Thank you
These things are scary! I mean who wants to come to a complete stop with minimal effort?? I've gotten used to squeezing the ever loving crap out of my Shimmy's to come to a slow rolling stop for over a year now! With my new Hayes A4's I can wait until I actually want to brake to squeeze them....and only with a gentle pull of one finger! It's almost like Haye's wanted you to able to stop or something?!?!?!
I can't express how well these feel! I can brake easily with one finger on the lever now, and with confidence! Great combination of modulation and stopping power!
I have the A4 model for a few months, I am satisfied with the purchase.
I have a doubt.
When I have to do maintenance, can I use any DOT 5.1 Fluid?
Dot 5.1 Fluid and nothing else!
There are so many places I could start with the Dominion A4's, whether it would be the incredibly consistent, powerful bite point, the feathery lever stroke (which makes going back to a pair of SRAM/Shimano's feel redundant), or their unmatched modulation, but the truth is Hayes has made a product that stands out against all the other brands in my humble opinion. Not to mention, their customer support is next to none (try getting a new master cylinder shipped out to your door in 4 days (like I did from Hayes), from Shimano. Hint: it'll take more like 4 months... Shout out Matt K. !!)
I'll never look back at another brake set again. These have changed my riding exponentially. There's a reason Remy Metailler rides them, I suggest you find out for yourself, just like I did, you won't be disappointed.
Hayes FOR LIFE!
