Contact adjustment, also known as dead stroke or dead band adjustment, changes the point in the lever stroke where the brake pads come in contact with the rotor. Poppet cam technology accomplishes this without affecting the lever’s home position. Some riders prefer a very short stroke, or throw, when they squeeze the brake lever blade. Others like a lot of lever travel. The poppet cam adjustment covers both, and everything in between. Additionally, you can use our Top-Hat tool free reach adjustment to dial the lever blade position closer to the grip or further away. This feature combined with the poppet cam stroke adjustment allows the rider to tune the Prime brake exactly how they like it. This tuning can be done in the shop or at the trailhead before the ride, but the Prime takes it a step further. The tool-free dials and short adjustment ranges enable the rider to make stroke and reach tweaks on the fly, with the flick of the thumb. No other brake can do this for you. Top-Hat sets start point. Poppet cam sets end point (tire lock point). The two can be adjusted individually without affecting each other.

The poppet cam design has a flow path five times larger than that of the Stroker’s three port-timing holes. This increased flow will eliminate lever pump caused by heat buildup. Additionally, the reservoir allows the brake to compensate for brake pad wear. As the pads shed material, the pistons will slip and allow the pads to stay close to the rotor rub area. When these pistons slip, additional brake fluid is needed behind them. This equalization can only occur with a properly sized reservoir and an efficient flow path.

The bore of the Prime master cylinder does not have port-timing holes drilled into it. In a traditional system, a port or ports must be drilled through the bore in order for the brake fluid to be able to vent into and from the reservoir. This traditional design has been in production for decades and is a relatively simple and cost-effective design. However, the rubber primary cup or seal of the master cylinder piston must cross over these holes every time the brake lever is squeezed, and then back across when it is released. This wears on the rubber cup over time. Additionally, any burrs or imperfections in the port-timing holes will accelerate this wear.

Has anyone seen a bike that has 3 chains? I can’t find the real use of it, but it looks interesting.

Hey there!
Due to the lack of time I have, I have left a lot of articles in the “Drafts” section, still waiting to be published. School was not enough, so, for making it harder, my internet service provider decided that I do not deserve internet anymore. However, the problems were solved and we are up and running again.
Since last I have logged in, some wierd bots posted some “GIEOIGAEGOIAGAGA” type of comments, but that’s OK and I have dealt with that 5 minutes ago, using my l337 admin ass-kicking powers.
Keeping it on bikes, I’ll just put up the only picture of a damaged Specialized Demo frame I have ever seen. In my life. Really.

OK, so by posting this I want to assure you that we are nowhere near out of business or subjects ( new Hayes Prime news, a lot of interesting stuff out there ) ! I will start posting daily again, for your reading pleasure! I’m out!

 The guys at BlkMrkt bikes have released some pics of their new project, the Killswitch frame. The pictures created a lot of hype around this frame, and that is with a reason !

We are talking about a 100mm travel full suspension dirt/slopestyle frame. Unlike other BlkMrkt frames, this one is made out of Alu, not steel. The suspension design on it is called “Hammer link ” . This bike can be singlespeeded, so they had to find a suspension design that would not cause ” chain growth” . The 100 mm of travel are assured by a  custom tuned version of the X-Fusion 2010 02 RCX shock . The weight will be around 3,4 KG and the price around 1400 USD ( including shock, headset and seat clamp device).

The frame has replaceable drop outs ( horizontal, vertical or Maxle versions ), and the sizes will be :  S (21″), M (22″) & L (23″).

The frame will be available in Flat Black, Flat Grey and Flat Purple colours.

The frame seems to be very good; do not forget that BlkMrkt have invented the true street/dirt 26-inch wheel geometry !
