WHEN TO REPLACE YOUR BIKE HELMET?

WHEN TO REPLACE YOUR BIKE HELMET?

(Taken from the SNELL foundation’s website):

The five-year replacement recommendation is based on a consensus by both helmet manufacturers and the Snell Foundation. Glues, resins and other materials used in helmet production can affect liner materials. Hair oils, body fluids and cosmetics, as well as normal “wear and tear” all contribute to helmet degradation. Petroleum based products present in cleaners, paints, fuels and other commonly encountered materials may also degrade materials used in many helmets possibly degrading performance. Additionally, experience indicates there will be a noticeable improvement in the protective characteristic of helmets over a five-year period due to advances in materials, designs, production methods and the standards. Thus, the recommendation for five-year helmet replacement is a judgment call stemming from a prudent safety philosophy.

(The same explanation as above, but written in English):

You should probably replace your helmet every 5 years if you do not encounter any hard knocks or hits. If you have a stack and hit your head, replace the helmet, even if it shows no significant damage.

The glues and other materials to hold your helmet together will degrade and 5 years is the cutoff for safe helmet usage. However, sweat, cosmetics, hair gel, hair spray and other factors will further break down your helmet.

The Australian Sun is more powerful than most areas above the equator and will break down a helmet even faster!

Don’t forget that all the exhaust, nature’s elements, rain, wind, and….MAGPIE’s will degrade a helmet!

If your helmet even makes it to 5 years, please replace it!

CONTINENTAL TYRES: DID YOU KNOW?

 

German Engineering Since 1871

More than 100 years experience in the development and production of bicycle tyres has made Continental a unique company within the industry.

Continental is the only German bicycle tyre manufacturer to produce its tyres in Germany. Knowing this serves as a mighty incentive to our engineers and everyone else involved in the manufacturing process to constantly strive for further innovations.

In the research and development laboratories for Continental bicycle tyres in Korbach, Germany, the staff and engineers have been looking for the solution to one of the fundamental problems of tyre construction: The running properties of the rubber compound of a tyre are largely determined by three interacting factors: static friction (grip), rolling resistance and mileage. The dilemma is that you improve one of these factors, and in turn, worsen at least one other factor.

A tyre with maximum grip wears out faster and rolls slower. If one makes the tyre faster or more durable, then this in turn reduces grip. With the then current highest standard of compound technology, the Activated Silica Compound having already reached a very high standard of compromise, our developers wanted to take compounding to an even higher level. This lead them to venture into new territory, exploring new ways so that in 2005 they made a breakthrough in mixing technology, the first steps to what is now known as BlackChili. This revolutionary compound is based on the latest findings on polymer and other raw material research.

For BlackChili we refine newly developed synthetic rubbers with natural rubber with the proven high-performance tread compound. We use these rubbers with special nanometric carbon soot particles, which are optimized in shape and surface properties for best uses for the intended tyre. BlackChili Compound reaches an unprecedented of performance.

Tyres with BlackChili Compound reach an unprecedented level of performance. Compared to the previous best Activated Silica Compound, BlackChili tyres have 26% less rolling resistance, a 30 % higher friction value (grip) and a 5 % increase in mileage. BlackChili technology never stands still as it is continuously developed and tailored to the individual applications of new Continental tyres as they continue to be produced out of the Korbach factory. Whether on the road or mountain bike, speed and grip advantages are very noticeable. The complex compound technology is so sensitive that tyres with BlackChili Compound can only be produced exclusively in our German Korbach factory.

The following tyres in the Continental range feature BlackChili:

What Is Strava?

STRAVA is a madly addictive app that has cyclists battling to be the virtual king of the road. Strava is changing the way you ride!

Strava, a website and app, has brilliantly tapped the power of GPS to change the way millions ride. Strava turns your solo or group rides into a real-life computer game.

Strava works by allowing cyclists to upload rides recorded via its smartphone app or any GPS bike computer such as Garmin. Routes, be they 5km commutes or 100km+ rides are mapped alongside times and data such as power output. Members may follow each other and create “segments”, turning stretches of road into virtual race tracks.

If a route takes in a segment, Strava automatically ranks the rider’s time. The cyclist with the best time wins King of the Mountain (KOM), a name taken from the Tour de France, where pros fight to be awarded the polka-dot jersey for best climber.

Strava gives you a ‘virtual locker room’ where you can share workouts among friends.

Strava fans say: “A bunch of grown men trying to compare where they stand seemed like a silly thing to do,” “But then you get into it and realise how much fun it is and what it adds to your riding. You use it to find key climbs if you go somewhere new. If a friend does a long ride somewhere, I get an alert and can send them a note saying well done.”

Another Strava fan says: “It allows you to track your progress and see how you compare with others without having to go through the formal or scary racing process,” “I definitely try to beat other cyclists and the first time I got KOM I pretty much danced around the house.”

BEGINNER BICYCLE TIPS: BIKE SEAT HEIGHT

 

Saddle height controls the leverage for your pedaling. Too low and it puts stress on your knees, too high and you may rub the saddle excessively. Children, or their parents, often put the saddle low for safety and to build confidence but it doesn’t allow them to pedal efficiently and may make cycling more difficult. This habit of having a low saddle may then continue with them even when they become adults.

Maybe you’ve seen riders with their seat too low. They’re even painful to watch. Knees splayed out, lunging about, trying to get their knees over to make the next revolution. You can almost hear their knees slowly giving out with each turn of the pedals!

Seat too high? This is just as bad and can stress your knees in a different way! When your seat is amongst the clouds, your hips will rock side to side to compensate, which will make for some intense chaffing and rubbing (great for bodyglide sales!), while making your knees over extend, which may bring about pain behind the knee.

What to do? You’ve got so many questions and not enough answers!

You ask your Facebook Fans of course! Here are some of the great suggestions we received regarding easy saddle height rules as followed by some of our Facebook fans:

Of course a professional bike fit is always best! But for those of you who are casual and maybe don’t consider yourselves ‘serious’ cyclists, there are more tips below:

You may see a theme or consistent recommendation regarding bike seat height. One thing for sure, if you are riding a road bike, city bike, fixie bike, or ladies bike, if your feet can touch the ground when you are sitting, your saddle will definitely be too low!

While there are many sources and tips online, I hope some of these tips could help if you are starting out and need a basic guide or ‘rule of thumb’.

Also, please note that this rule may be different depending on the type of bike you ride. The setup for a full carbon road bike, will be different for a ladies bike, or other types of bikes (see below):

(Seat height for this one might be a little high for most)

(This woman has obviously found the best seat height for her)

I leave you with a final technical schematic diagram to remind you that a saddle that is too high or too low will keep you from enjoying your riding! Please find the best height for you!
