CROSS IS COMING!

August 20, 2019 / Bicycle News

Cross is coming, and with it comes all the questions about tire selection and tire sizing.  Our friends at USA Cycling were kind enough to share their WHY, WHAT, WHERE, and WHEN's for cyclocross regulations and how that effects riders and their bikes.  The regulations below come directly from the USA Cycling website and can be viewed in the resource section by clicking this link: CROSS FAQ.   

Cyclocross Equipment and Regulations FAQ

We publish eligibility and equipment rules for all of our National Championships on our website on the National Championship Page. Even with this published information, many of our members still call with concerns and questions about what’s legal, universally falling victim to, “someone told me”. So, here’s the 411 for cyclocross equipment:

WHY

In order to understand the regulations that apply to your event, please appreciate that USA Cycling and the International Cycling Union (UCI) have regulations related to cyclocross racing. Isn’t a bicycle a bicycle? For USA Cycling, the answer is yes, but with a few details. For the UCI, they have a robust set of regulations that, for the most part, are to make sure that what everyone understands as a bicycle, used in competition, still looks enough like a bicycle that 95% of the people in the world would recognize it. For most local events, the requirements are very basic.

Because of the popularity of cyclocross (CX) in the United States, it has quickly become one of the few disciplines in our sport to truly “go international”. As many events became part of the UCI’s international calendar, suddenly, there were more rules and regulations to pay attention to. Although the principals are really the same, the details matter. Bike design, bike equipment, and tires especially, become areas of misinformation.

WHAT-Regulations

USA Cycling has extremely generous bicycle regulations. If it’s a pretty standard bicycle, you are welcome to race it in our events. These regulations are found in Chapter 1, specifically starting in 1I (that’s one-i). What do you need? Two wheels, self-propulsion with a circular pedaling motion, a bike less than 2 meters long or 75 cm wide, brakes and handlebars (yep, there are things missing). Note that most local CX events will fall under the first category below.

USA Cycling Regulations: See Chapter 1. Simple.

  • Two wheels
  • Handlebar (dropped or straight-but no bar-ends that extend forward or upward)
  • Brakes, no forearm supports/extensions
  • Freewheel
  • Saddle
  • Pedaled in a circular motion
  • No metal studs in tires

For example: Mountain bikes, hybrid bikes, single speeds, and even beach cruisers are okay for USA Cycling Regulation CX events as long as they meet the requirements above.

USA Cycling Regulations with UCI Light:

  • USA Cycling Regulations +
  • Double triangle frame shape
  • Drop handlebars
  • Wheels same diameter
  • Tire width-35 mm maximum (when inflated and ready to race)
  • Saddle
  • Freewheel

UCI Regulations:

  • Tire width 33 mm maximum (when inflated and ready to race)
  • Drop (traditional) handlebars only
  • Chain drive
  • Pedaled in circular motion
  • 2 wheels, same diameter between 550 and 700 mm
  • Saddle
  • Brakes (one on each wheel)
  • Freewheel
  • Shifting mechanisms/brake levers (that don’t extend excessively to become a place to rest your forearms)
  • No metal studs in tires

WHEN/WHERE

UCI calendar races-UCI Regulations:

  • Elite, Juniors and sometimes U23 riders depending upon the event. All of the UCI Regulations affecting bike equipment apply. For everyone else, see USA Cycling Regulations.
  • Masters at Masters World Championships

USA Cycling National Championships

  • UCI Regulations-Elite, Junior (17-18) and U23 
  • USA Cycling Regulations-Junior under 16
  • USA Cycling Regulations with UCI Light-Masters

USA Cycling Local Events (INCLUDING amateur events at a UCI level race):

  • USA Cycling Regulations 

Our national championships are an important part of what USA Cycling governs. For those events for the rider classes of Elite, Junior (17-18) and U23, we require that bikes and equipment meet international standards. This puts us on a level playing field with the rest of the world and our riders, eligible for World Championships, know that there are no mysteries or last-minute changes that they will be forced upon them for bike/equipment/set-up on the world’s biggest stage. As Masters World Championships have grown in popularity with USA Cycling’s Master competitors, they too have had to adapt to the world stage of international cyclocross. For that reason, we have added a small layer of what we refer to as “UCI light”, in order to set the stage for an easy transition to international events.

People powered. In addition, self-propulsion is a component of both local and international bike racing. This means no motor in the bicycle. All bicycles at any level of racing are subject to motor checks (mechanical doping control).

So, what do these regulations mean to you and why are they on Kenda's website?  Well, the reason we have published these rules is because almost 10 years after the UCI implemented their maximum tire width regulations there are still many people who do not know when or if the regulations effect them, and their choice of tire for cyclocross. The chart below details Kenda's cyclocross (and gravel) offerings as well as what sizes are or aren't compliant with USA Cycling and the UCI's rules.
