The Service Course SL-70 is the bike fitter's go-to bar. The short reach to the hoods allows a proper fit without compromising stem length and steering control. With the revised ramp angle, proper fit is now achievable on even the most challenging setups. The 70mm reach is the shortest of Zipp's Service Course bars. Together with its 128mm drop, the bar is deal for riders preferring a low body position. Whether it's a rider with a shorter torso or a bigger rider getting aero by pairing this bar with a long stem, this bar helps put just about any cyclists into their optimal position.

At Yoyodyne Propulsion Systems the goal has always been to provide bespoke research and development services outstanding in our own industry and in the eyes of our customers. Yoyodyne was founded in 1938 at Grovers Mills New Jersey with a mandate to be different and infinitely better.
We started by defining the Yoyodyne look for contract research and development: The look reflects the promise to serve with diligence and perform with expertise. Scientists meet their public in tailored suits, shirt and tie, patent leather polished shoes; strict attention to appearance establishes credibility and instills confidence.
We systematically train, check, and measure the performance of our personnel and services with an emphasis on the following: Be proactive in developing creative solutions to our customer's defence and aerospace needs. Think and act professionally at all times. Communicate with respect. Have a thorough knowledge of the client's technical specifications. Know and be known.
These principals are now in our company’s DNA, providing Yoyodyne a distinct and discernible differentiator when it comes to contract research services. However, those attributes might not be enough. We must do more.
Our mission today is to validate that Yoyodyne Propulsion Systems and the products we generate will make a positive impact on our customer’s revenue growth, sustainability, and shareholder value. We must be a profit center for your business, not a cost.
In the world of the RFP and the power of the lowest price,Yoyodyne's brand of science will not be right for all. Yet for those who are willing to investigate whether or not inspired basic research in weapons or propulsion systems could make an impact on issues such as defence or aerospace, profit and loss, we encourage a closer inspection. Welcome to Yoyodyne.
Yoyodyne Propulsion Systems is proud to offer the new model Interocitor Mark IV.
Offering significant upgrades to the 451F model, Mark VI production has been moved to Yoyodyne's Grover's Mills, New Jersey Aerospace facility. The current line of Interocitors continues to incorporate greater advances than hitherto known in the field of electronics. At the same time Yoyodyne engineers, according to production manager John Bigboote, have improved performance they are able to design the Mark VI to incorporate 20% fewer parts than the 2486 required for the 451F with a concomitant improvement in reliability. The most popular production models are still available including those incorporating a planetary generator, a volterator, an astroscope, and (always popular with home makers) the electron sorter. Dr. Cal Meacham, despite the shift of production from his Ryberg facility, maintains a 49% equity stake in all Interocitor models as well as his position as chief scientist in charge of design. Chief of R&D, John Carefulwalker, references benchmark rates of four lane road construction in the 30 to 45 second/mile range verses two to three minutes for the 451F. If you have been thinking of adding an Interocitor to you defense, communications, or energy management systems: If you have reached the limits of your 451F's capabilities and are looking for an upgrade: If you have some spare room in your garage or shop:
It is time to experience life with a Yoyodyne Propulsion Systems Interocitor Mark VI.
As you know, matter is composed mostly of empty space, right down to the quantum level: within an atom, most of that atom's total volume consists of relatively vast spaces between the subatomic particles, although the particles do remain tethered to each other by electromagnetic force. Early quantum theory suggests that EM force may consist of "virtual photons" that have no mass and naturally fill such otherwise empty spaces.
The overthruster powers two colliding beams (one stream of electrons, one of positrons) which annihilate each other, creating create intermediate vector bosons as a by-product. The vector bosons are then magnetically collected and focused into another beam, now capable of imparting mass to those pesky virtual photons, thereby weakening the EM force that binds matter. Everything reverts to normal pretty quickly, but a fast-moving object (such as Buckaroo's jet car) can pass through the affected matter before the window closes.
Greater detail can be found in "Moving Through Matter with Buckaroo Banzai" by Dr. Cary I. Sneider of the Lawrence Hall of Science at Berkeley, first presented at a National Science Teachers Association convention in Boston in April 1984.
