The Recumbent & HPV Information Center Top Stories | www.dirtragmag.com Buyer's Guide / Cantilever Brakes - Bicycle Parts at discount pr We have added a feature to our writing about cantilever brakes which we call the "Bike-Pro profile measurement" This is the distance expressed in millimeters from the center of the mounting stud to the end of the arm. The measurement is made as though the each arm were installed. The left and right arm measurements are added together to come up with a "Bike-Pro profile measurement".

Keep it simple. Make it better. WILD MOTION Yetifan.com The Curious Wavefunction Cycling News and Bike Reviews for Road Bikes, Mountain Bikes, BMX and More - Bike Rumor The Hub - Hublog of The Hub at Backcountry Outdoors WD-40 is not for bicycles, bike chains, bike gears, bike pulleys, bike cables nor bike tires. Nothing! WD-40 does not belong on your bike! A short history of WD-40 from Wikipedia. WD-40 is the trademark name of a United States-made water-displacing spray. According to Jimi, our wise old service manager, the one and only actable use for WD-40 on a bike is to help loosen a stuck part, but then added that PB Blaster is far superior to WD-40. WD-40 isn’t actually a true lubricant. So on your bike chain you should use a DRIP (not spray) lubricant designed for bicycles. Tri-Flow® Superior Lubricant is the superior, light viscosity lube that allows for deep penetration into hard to reach moving parts. How to properly lube your chain: 1. 2. 3. 4.
Bruce Booth - Life Sci VC Biotech IPOs have long been viewed with skeptism, especially over the past few years in comparison to the high-flying media darlings in the Tech space. But recently a number of the social media phenoms have fallen from grace: Groupon is off 72%, Zynga is off 68%, and Facebook is off 44% as of today. Yet during the past 12-18 months, new Biotech IPOs have quietly been putting points on the board with their post-IPO performance. It’s now fair to say they have resoundingly outperformed their Tech cousins in the public markets. According to the National Venture Capital Association, 83 venture-backed IPOs occurred since January 2011 through end of 2Q 2012: 15 Life Science deals and 68 “Technology” deals (which include social media, retail, software, etc…). Biotech median and average percent change since IPO are +19% and +26% versus Tech performance of -9% and +3%, respectively. But all deals aren’t created equal. The outliers don’t even breakout in favor of Tech.
Hydraulic brake device patent - Ashima Ltd. 1. Field of the Invention The present invention relates to a hydraulic brake, and more particularly to a hydraulic brake assembly used to apply opposing brake loads on the wheel rim of a vehicle such as a bicycle, a motorcycle, and the like. 2. A conventional rim brake in accordance with the prior art comprises a pair of left and right arms pivotally attached to a frame of a bicycle, each having on its distal end portion a brake shoe, and a spring for energizing the arms to move toward brake releasing direction. A conventional hydraulic brake in accordance with the prior art comprises a hydraulic cylinder, a piston movably received in the axial direction of the cylinder, and a brake pad connected to the piston. The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional rim brake and disk brake. The main objective of the present invention is to provide an improved hydraulic brake device of a vehicle such as a bicycle, a motorcycle, and the like.
In the Pipeline: Improving Chain Lubrication The majority of chains used in industry suffer unnecessarily short lives. This leads many companies to forego chains all together and replace them with belts. In most cases, however, the problem is not the fault of the chains but rather the method in which they are lubricated. The current chain lubrication practice consists of applying a heavy oil or grease to the outside of the chain. The majority of chains fail from the inside. Figure 1. A penetrating-type chain lubricant not only displaces water, but also cleans dirt and wear metals out of the pins of the chain and off of the sprockets. The operating conditions (including load, environment, temperature and speed) must also be considered. The method of lubrication is equally important. Lubrication is required between the rollers and bushings, but other important areas to lubricate are the pin and bushing surfaces, which articulate with each other while the chain is under full load.
