    New Hayes Prime Disc brakes

    These new brakes look rather interesting. I wonder what the price and weight will be for the pro version?

    from the google:

    Target weight for the Pro is 385g for a complete front setup with 160mm rotor and the Expert is slightly heavier at 415g. Projected prices are aggressive across the board with the Prime Pro costing US$209 (UK prices TBC – direct currency conversion is £133) per wheel and the Expert model just $179 (approx £114). Consumers should see Prime on store shelves from June 2010.

    Improved Reach Adjust

    Tool-free design that is independent of the contact adjustment. This feature has improved durability and aesthetics over the existing Stroker design. Additionally, mechanical advantage is fixed regardless of lever home position. This means you get the same power and feel with the lever set close to the grip as you do with it set further away.
    Mechanical Leverage Ratio

    Increased throughout the entire lever stroke, resulting in a high power level later in the stroke. This promotes progressive braking that is more predictable (modulation).
    Hydraulic Power Ratio

    20% increase in hydraulic ratio over the Stroker Trail. Higher clamp force on the rotor is reached with the same given input at the lever blade.
    New Technology: Components

    Performance Hose- A new four layer low expansion hose tuned for the Prime’s high mechanical and hydraulic ratios. Power transfer to the caliper pistons is more precise and system feel is more consistent regardless of front and rear hose lengths.

    Hayes Tube Tops- Protect the frame’s head-tube and headset cup finish from abrasion and wear at the point where the hydraulic hose makes contact.

    Rotor- New low noise and high Mu two-piece rotor. Carries on the original Hayes sweeping fin design patented in 1998, but has a new rub area and is stiffer than the standard one-piece design. At 110 grams for the 6” version, it is also lighter.

    Prime Hardware- Nickel plated, titanium and anodized aluminum fasteners resist corrosion and maintain the high-end finish. All hardware is designed and tested to meet precise torque values.

    Lever Bushings- New press fit Titacon CL 500 bushings are used in the master cylinder body. This results in precise tolerances and better bearing surface between the lever blade and the body. The system will have smoother actuation and no lever slope.

    Clamp Attachment Method- A new two-piece design that allows the master cylinder to be removed without affecting other handlebar components. This offset system is tightened to a stop on the primary side and tightened with a torque wrench on the secondary. This distributes the clamp force evenly on the handlebar and aids in proper assembly.

    Really cool looking. I wonder why the photo is pixelated in the center?

    hayes is trying to spark interest in their version of pad contact adjustment. you can pretty much figure out what it looks like and how it will work from the drawings on the hayes prime website. regardless of the 'new technology', i'm pretty sure the end result is turning a dial or lever will increase or decrease when the pads contact the rotor.

    "Why is the Poppet Cam (stroke adjust dial) blurred out on the new website?
    This is the new technology for Prime and all Disc brakes. We didn’t want to “blow our load” all in one shot. We will reveal all of the information regarding Poppet Cam and the guts of the Prime in two weeks." leelikesbikes.com

    Well, it sounds like they are trying to address some of the shortcomings of their Stroker line.

    If so, and it works, that's a good thing.
