Product Description
Park Tool CC-4 Professional Chain Wear Indicator Tool
One of the first time-savers they invented was a stand that held the bike off the ground allowing easy, back saving access to any part of the bike. This original stand was put together using legs from a dining room table, an empty shell casing and a truck axle from a 37 Ford. As other shops, and eventually Schwinn Bicycle Company, saw the stand in action, requests were made for a production model. Park Tool Company was born!
The line grew quickly to include a wheel truing stand, more repair stands including a double arm shop version, wrenches gauges, fixtures and consumer tools soon joined the company's offerings. The retail side of the business also grew earning Top Ten Schwinn dealer status fifteen years in a row including number one overall in 1977. In the early 1980s all three retail shops were sold to concentrate on the tool business.
Park Tool CC-4 Professional Chain Wear Indicator Tool
The CC-4 is a drop-in style gauge that measures bicycle chain wear
The laser cut CC-4 accurately measures a long section of chain and strategically comes in contact with the chain in three places, quickly and easily taking the guesswork out of knowing when chain replacement is necessary
A worn chain will cause poor shifting as well as accelerate drivetrain wear
The CC-4 works on any 5 to 12-speed derailleur chain (including SRAM AXS) and is designed to accurately indicate when a chain reaches .5% and .75% wear, the points at which most chain manufacturers suggest replacement
Made in the USA and covered by Park Tool's legendary limited lifetime warranty
