CrankCase Is The Only Bicycle Chain Cover You'll Ever Need!

CrankCase display at Ironman Lake Placid 2012

CrankCase™ inventor, Jane Tunnicliffe Stine, brings more than thirty years practical knowledge and understanding of cyclists’ needs to the design and construction of CrankCase™. A cyclist, competitive runner, mountaineer and life-long traveler; Jane recognized the need for a professional-quality bike transport from first-hand experience. Hesitant to carry her cycle outside her vehicle, she also knew that carrying it inside meant that chain grease and outdoor debris would get all over the interior of her new car and leave the crank, gears, chain, derailleurs, and pedals vulnerable to potential damage.

Dissatisfied with makeshift covers like towels and garbage bags, Jane designed the prototype of the CrankCase™ from an old pair of khaki pants on her living room floor. She then worked with a leading textile company where her vision was coupled with the manufacturer’s knowledge of high quality nylon and the superior product that is CrankCase™ was born.

CrankCase™ is in use by competitive cyclists everywhere and was featured at the 2012 Ironman Lake Placid. We remain committed to providing all cyclists with a professional, durable, easy-to-use protection from grease and grime.
