PRESS RELEASE: Hayes
Hayes have announced a limited edition version of their Dominion A2 brake that shaves 50 grams per brake. The A2 is a slimmed-down, 2 piston version of the A4 meant for XC and trail bikes and this new version, the T2, goes lighter again thanks to some carbon and titanium upgrades.
Each brake now weighs 254 grams, thanks to a carbon lever produced in house by Reynolds, titanium hardware, a composite reservoir cover, pads with aluminum backing plates, and precise weight-reducing machining. There have also been some internal tweaks such as an added glide ring on the master cylinder piston and sealed ball bearings at the lever blade pivot. These updates are said to reduce friction and "keep the lever feel as lightweight as its carbon construction".
As in the A2, the brake has no dead stroke, meaning when riders move the lever, the pads start to move from the beginning of the stroke, and the bite point and lever reach can be adjusted using a 2mm allen key. Also brought over from the A2 is the 2-stroke dual-port bleed system that allows users to isolate your bleed to the caliper where air bubbles can hide behind pistons and the Crosshair Alignment screws on the caliper mount that allow riders to fine-tune alignment.
Hayes' D-Series rotors are designed to work with the calipers Semi-Met T106 pads, to cancel out noise and vibration. The T2 utilizes aluminum backing plates on the standard Semi-Met T106 pads to further reduce weight. Titanium rotor mounting bolts are included with every T2 Brake Kit for extra gram reduction.
The T2 is available now but is limited to just 500 sets. The brake retails for $289.99 or €258.83, which is around $60 more than the standard A2 brakes. More information on the brakes can be found, here
10/10 in my experience. Not one issue in the last few years.
I'd love to try a brand other than Shimano/Sam but its a decent investment to something that I have no idea if I'll genuinely like
Dominions beat them hands down. Consistent reliable bite point, consistent reliable bleed, consistent reliable power that hauls on in a nice ramp up to all the power that you could want.
Cunningham crowned them component of the year, other reviews have similar things to say. They aren’t as cheap as Shimano, but they aren’t cheap like Shimano. They come with spare pads and barbs. Buy them.
quick disconnect feature super cool, when you route brake intently or through fork , so you do not need to bleed after fork service;
the only downside - all spare parts should be ordered from EU, which is kinda annoying, when you bend lever or so;
My weight around 185 + gear comparing to SRAM and Shimano those are super consistent and reliable;
I've also been on Cura 4's for about a year now and they are the best brakes i've ever used(been on saints,xt 4pots etc)
I have also used Saint, Code, ... in the past but with my 95kg every brake has some negative sites. With the A4 - no problem's!
The (Do)minion's are the best! ????
