Clement cyclocross tires such as the MXP and PDX have become very popular among cyclocross riders. The Clement name was being licensed by Donnelly Cycling, but that relationship is ending this fall. Donnelly Cycling will continue to offer the popular Clement products, but under the Donnelly Cycling brand name. 

Also, the three-rider Clement team of Lance Haidet, Laurel Rathbun and Jamey Driscoll will also be racing under the Donnelly banner this season. Read this release for more information. 


Donnelly Sports LLC, which has been licensing the Clement name from Pirelli, is ending its use of the trademark with the Italian-based tire brand. Donnelly Sports owner, Donn Kellogg, will launch the tires and wheels under the brand name, Donnelly Cycling.

Kellogg began licensing the Clement brand name in 2010 and revitalized the 130-year-old tire brand by developing new road, cyclocross and adventure tire tread patterns. The designs–many of which have been raced to World Cup and National cyclocross titles–are owned by Kellogg and will continue under the Donnelly brand name.

“The tread patterns, the tire model names and the wheels were all designed here in Colorado beginning in 2010 at the time of trademark licensing,” said Kellogg. “People ask for our tires by model name such as PDX, MSO, and USH which will all be rolled under the Donnelly brand name.”

Donnelly-branded products will be released in mid-September beginning with cyclocross tubulars. Clinchers for cyclocross and gravel will follow. Long-awaited wheel sets, media-tested at last year’s Colorado to Interbike Beehive Ride, will start to land toward the end of September.

The Donnelly brand will emphasize its home base of Colorado. The new packaging will include the state licensed “Colorado Designed” logo. “We are proud to be a Colorado based company,” Kellogg said. “It’s a world-class destination for all genres of cycling. The strong cycling community here is on the highest level, which is an integral part of our design, development and testing team. This has allowed us to develop each individual tire for very specific riding and racing conditions. We’re a young company that will continue to make products that are well ahead of the curve.”

The long-running and highly successful cyclocross team the company has supported and managed will continue with U-23 National Champion Lance Haidet, Jamey Driscoll and Laurel Rathbun racing under the Donnelly banner this year. The team was known as Raleigh-Clement last season.
