Calling the Catlike Vacuum Helmet the most conventional looking helmet in the 2012 Catlike line would be tantamount to arguing that Cippolini's pink skinsuit for the 2005 Giro was his most conservative wardrobe choice. Granted, it's not as immediately memorable as Catlike's top-shelf Whisper Plus (the equivalent to Cippo's zebra-striped skinsuit), but for many of us, that's probably a good thing. More important though, is that the Vacuum is an economical alternative to the Whisper Plus, while retaining the clean lines, complex technologies, and overall striking aesthetic choices that Catlike is best known for. Like all Catlike helmets, the dramatic appearances aren't without rhyme or reason. Each design is intelligently engineered to enhance the helmet's ventilation efficacy while maintaining the strict safety standards established by CPSC. The Vacuum is constructed around Catlike's Air Tube System, which, similar to the structure of the Catlike Sakana (another radical Catlike design that is not currently available on U.S. shores), is a series of small tubes connecting the helmet's segmented 'fins' together. While elegant, the design also cleverly divides the helmet into impact-absorbing crumple zones that dissipate energy at the time of a crash AAA not unlike the skeleton of a compact car. These fins strengthen the core structure of the helmet, and allow Catlike's engineers to reduce weight in other areas, giving you a helmet that tips the scales under 300 grams in all three of the available sizes. The fin structure also opens up a wide range of possibilities for ventilation. The Vacuum has 19 generous vents, most of which run lengthwise around the helmet along the Air Tubes. Each forward-facing vent has a matching rear exhaust vent to keep a constant and efficient circulation of cool air over your head while you ride. The Vacuum uses the same MPS (Multi Position System) retention system as the top-shelf Whisper Plus.

Light weight lugging a vacuum from room to room,floor to floor is enough to make where you can say, "People can live with those crumbs!"But DIY light weight weighing system which takes the torture out of toting.Weighing scale system which can just 16 pounds its third less than a typical upright,but ...

I bled my Avid Elixir brakes yesterday and one of the first steps is to place the brake fluid under a vacuum by pulling on the syringe plunger. I thought about this for a minute and believe I have a better way of doing it. When I raced RC cars I had a shock vacuum chamber such as the one at this l ... Read More »
manual bleeding cars is basically not done anymore.. just takes too long, and does too poor of a job! in terms of design, bike brakes are nearly identical to car brakes, except with 1/4th the components.. seems like we could vacuum bleed them too, but no one seems to?

I have been riding on an 08 Reba Race for about 3 months now. The past couple rides, whether it's singletrack or rails to trails stuff, my positive chamber loses air pressure whereas the negative chamber gains air pressure, creating a vacuum inside the fork and compressing it.
