Health Benefits of Cycling


SALLY WRITES - In the year 2000, Americans made approximately 2 billion trips by bike and as of 2017, a whopping 66 million riders were recorded. In fact, statistics show that many Americans choose cycling to keep themselves healthy. While cycling provides a good workout, cyclists still need to pay attention to their food intake. Nutritionists note that the right blend of minerals and nutrients can help keep the body strong and healthy even during intense bike rides. They also add that the right nutrients eaten at the right time can also help the body recover faster. However, even seasoned cyclists make nutrition-related mistakes. :: More

Clement Tubless tires now available in U.S

We first got word of the Clement BOS tubeless cyclocross tire last year at Sea Otter, and then saw early images of it back in September at Interbike, but now we have our hands on one of the first sets to land.


The Clement BOS tire is named after Boston’s Logan International Airport three letter code, in typical Clement cyclocross/gravel tire style (other tires are the LAS, PDX, MSO, USH). The BOS is billed as a mud tire.

Andrew Austin | Ebikecatalog.com — When it comes to e-bike maintenance, many people can feel confused or even overwhelmed. This is why it will actually prove important to understand they are just as easy to clean as regular bikes. This means that a good cleaning routine can have a positive impact on its overall performance.

There are a couple of options you can choose from when it comes to proper maintenance. The first option would include taking the bike back to the dealer if your local shop has this regular service and maintenance package. The second option will be easier, as you will be the one responsible for good cleaning and maintenance.

FUG Brands Introduces Premium Lubricant


You wouldn't think that a dry lubricant formula would perform better than a wet formula, would you? But it does. Why?

The FUG It! formula was developed for aerospace where it’s mission critical to keep particulate matter and debris away from highly sensitive moving parts and components.


It's no different for gears, chains and moving parts on bicycles, motorcycles, cars, garages and around the house. Keeping dust, dirt and debris  from sticking to moving parts is half the battle of keeping things running smooth without squeaking, squawking and promoting premature wear and tear. 

FUG It! Premium Grade Multi-Purpose Lubricant is made from a superior quality of liquefied petrols which are biodegradable, a bonus for your trash can and the environment. The spray canisters formerly designated as pepper spray cans for law enforcement contain Co2 as the propellant (that's the same stuff in soda cans) versus propane or butane. A short nozzle and 2.6 oz size make for a convenient carry anywhere size.   :: Shop Now.

Boulder, CO—As the CX season heats up Donnelly Cycling looks to the year ahead with newly branded tires and a fresh outlook for 2022.

A tradition of extraordinary tire design evolves into an American brand. For more than 10 years Donnelly Sports has been developing cycling tires under a classic Italian name. Race tested models that have become so ingrained in the sport will now pay homage to their Boulder, Colorado home and bear their founder’s name. CX tires like the MXP, PDX LAS and BOS. ADVENTURE tires like the X’PLOR MSO, and X’PLOR USH. And ROAD tires like the Strada LGG, LCV and CDG. The Donnelly brand name may be new, but the model names, production materials and methods will remain the same.


All good things evolve. Donnelly Cycling—Same race tested tires, more familiar name.


SPECIAL ANNOUNCEMENT: Donnelly Cycling is moving to a new distribution home.   :: Shop Now.
