Triathlon Wetsuit

Bike riding is one of those sports that anyone can enjoy and the benefits are almost limitless. Some use cycling as a means of getting from A to B, whilst others cycle to boost their fitness and tone up their muscles. The fitness benefits for your muscles varies quite a lot depending on which type of cycling you do. If you cycle very long distances at relatively low intensity, your muscles will become very good at endurance and will build many slow-twitch fibres. Conversely, if you ride at a high intensity over shorter periods, you will develop more fast twitch (powerful) fibres and build muscle size. So which muscles get worked the hardest when you ride a bike.

Quadriceps (thighs). The muscles that are worked the hardest whilst cycling and so need to be the most developed are the quads. These muscles work to extend the knee joint and provide a downward force on the pedals, which is then passed onto the crank. Racing bikes in fact are designed to locate the quads directly over the crack so that maximum efficiency is achieved. When cycling fast, these muscles are contracted and relaxed hundreds of times a minute and so they need to be in good shape.

Gastrocnemius (calf muscles). Although the calf muscles are much smaller than the quadriceps, they still do and important job of transferring power to the pedals.When the leg is straightened by the quadricep muscles, there is still a percentage of power that can be gained by flexing the calf muscles and pointing the toes downwards. Pinarello make pedals that dynamically pivot to squeeze every last bit of power juice from the calf muscles.

Hamstrings. It may be the thigh muscles that provide most of the forward momentum when riding, but in order to flex the legs and prime them for the next downward push, it is the hamstrings that do the work. This doesn’t require much force on a standard bike as the rotation of the pedals pushes the leg up but when you use cycling shoes that clip to the pedals, a large amount of additional force can be generated by these muscles in the upward movement

Bmx bikes are expressly durable given the nature of the sport which includes high speeds, repeated jumps and occasional crashes and are presented in an assortment of sizes to accommodate all types of riders and all ages

BMX bike frames are constructed of lightweight metals and components in order to be lifted, and catapult in the air, without the additional weight deterring this component and are expressly durable given the nature of the sport which includes high speeds, regular jumps and occasional crashes.

BMX bikes are expressly planned with a low profile cromoly frame, solitary pace gearing, gyro brake system for frequent turns of the handlebar without tangling the brake lines, and hinge pegs for additional foot placement during tricks and as in all racing bikes, the frames are stiff for maximum power transfer and the wheels are light for faster acceleration.

The wheels and tires that are put on BMX bikes can be different, then again the tires are made with diverse treads, and include textures to grip services, and thwart slides on dangerous tracks and scales and some BMX bikes are built from strong heavy metal and these are less prone to yield to damage than the lighter ones, however you should still be watchful when looking.

These bikes are made of wonderful way and you can of course acquire expert bmx bikes suited mostly for stunts, or bmx bikes planned expressly for dirt racing, on the contrary all bmx bikes are usually than not

Dirt jumping is also a well-liked sport which uses BMX bikes, and there are even bikes built distinctively for this purpose and are the just right choice for individuals riders of bmx bikes who comparable to play roughly, these bmx bikes are famous for their toughness and resisting the strain that any dirt racing, stunts or freestyle riding may put upon a bmx bikes frame.

Freestyler BMX bikes vary from standard BMX bikes in a few basic areas in that the frames and forks are normally stronger, the wheels are more robust, specially if they have 48 spokes (instead of the usual 36), the headset unit is a GYRO type, which means that the handlebars can constantly be spun round with no the brake cables tangling up and these bikes are more light weight than freestyle bikes, however are durable enough to take on street/skate-park trick riding.

One of the best sites to understand all about BMX bikes and the world celebrated Mongoose BMX Bikes is http://www.mongoosebmxbikes.org/ full of stunts tip and tricks plus much more.

Less than a month before release, Genesis has finally released details and images for their 2010 lineup. Depsite all these bikes being part of the 2010 lineup for Genesis, they are actually being released in September 2009.

It looks like Genesis will be returning to the road bike market with their 2010 bike lineup. The first bikes up on the list are the Aether 10 and Aether 20 racing bikes.

The Aether bike has really been designed for the daily commuter. Both feature ALX-9 aluminium frames as well as carbon-legged forks. However, everything comes at a price and this is no exception. The cheaper of the two models, the Aether 10, features Shimano 2300 and Sora parts, all for £599.99. If you want to go for the Aether 20, this is will cost you another £200. A mix of Sora and Shimano Tiagra parts is what makes up the bike, and the £799.99 price tag.

The next bike is the Vapour. This model features an ALX-9 6069 aluminium frame and will cost £849.99. To go alongside your lightweight frame, you also get a mix of Shimano Tiagra and Sora parts, plus a new front hanger mount, designed by Genesis to supply better braking.

The final road bike on Genesis’ list is the Flyer. This one is a singlespeed bike and features a number of stylish bonuses. This bike is made from a Reynolds 520 steel frame, with features such as chrome cable clips and a white chain. This bike will cost you £599.99, not a bad price for such a good looking city bike. The strange thing is that this bike doesn’t feature any bottle bosses so you can attach any bike accessories, I guess Genesis must have assumed that if you own one of these, you don’t sweat through your cycle clothing.

Along side this array of road bikes revealed also came a range of improved mountain bikes. The first one of the list, the Core, comes in two different varieties. There is the Core 40 which will cost £999.99 and then there’s the more expensive Core 50 which costs £1,199.99.

The next one up is the Alpitude costing £1,699.99, not to be mistaken with the Altitude, features a Reynolds 853 steel frame, perfect for long trails.

If you’re looking for a relatively cheap mountain bike, the new iO is the best suitted. There are two different versions, the singlespeed for £599.99, or the more expensive eight-speed version which costs £1,099.99. Both versions come with a Reynolds 520 steel frame.

The final bike in the lineup is the Altitude, and it comes in 5 different models. Built with the Reynolds 520 steel frame, these two models are the cheapest, the Altitude 00, costing £799.99 and the Altitude 10 costing around £999.99. For a more expensive ride, the Altitude 20 is the next level up. This model features a high quality Reynolds 853 steel frame and will set you back a whopping £1,449.99. Skipping the fourth model, the final and most expensive model is the Altitude Ti. This final model features a titanium frame and comes at a staggering £2,799.99.

The hybrid bicycle has been around for a few years, but it is becoming increasingly popular now, both with commuters and leisure cyclists alike. With pressure to use the car less from environmentalists and ever increasing fuel costs, the hybrid bike is becoming a credible alternative to the traditional commute to work in the car.

So just what is a hybrid bicycle?  They are essentially a cross between a mountain bike, a touring bike and a racing bike. Mountain bikes are probably the most popular choice for general cycling, particularly off-road. But when on the road they can be cumbersome and heavy, with the deep tread tyres creating a drag on the road surface.  The hybrid bicycle uses mountain bike features such as suspension and wider tyres, but on larger diameter rims such as those found on racing bikes. The tyres have a flat section in the centre, to reduce the drag effect on the road but still have the usual knobbly tread on the outer part of the tyre for grip off-road. Most people wouldn’t imagine riding to work on a racing bike because of the discomfort over a longer distance, particularly in rush hour traffic.  Similarly a mountain bike isn’t ideal because of the tread on the tyre and the lack of storage for work items.

Some models also feature panniers for storage, something normally found on touring bikes. The gears are similar to the mountain bike, featuring around 25 speeds or so, as do the handlebars which are flat. They are relatively cheap as well, when compared to a racing bike or mountain bike and because of the all round nature of them, just one bike could be used both for the commute to work and at the weekend in the park with the kids.  Cheap bikes can be found just by going to Google, or down at the high street where you of course have the luxury of being able to try them out first!

Its an amazing fact but sometimes in road racing, a few grams can mean the difference between winning and losing. Pro cyclists are on very strict diets and watch their weight very carefully, but the racing bikes also need to pretty trim. The average decrease in weight that time trail bikes have seen in the last 10 years in quite amazing, dropping at a rate of 7-11 grams per year. If you’re thinking this is nothing, there are a million riders who will testify to just what a difference this makes. So what are the latest developments to come on scene, aimed at shaving another few pounds off?

Carbon fiber shoes. When it comes to cycle clothing, light and strong is the key. Cyclist like their shoes to be a solid as possible so that non of their energy is lost through shoe flex. Traditionally there has been a tossup between using hard materials which were usually heavy or lighter ones that softer and not as effective. New carbon fiber shoes however solve the problem by being very light but also incredibly strong

Lightest spokes. Spokes may look pretty small and insignificant but the combined weight of all of them can make quite a difference. Some spokes are now being made out of carbon fiber but they have to be thicker in order to have adequate strength. The preferred option is now titanium spokes Zipp wheels have adopted and can be made to the same size steel ones, but are around half the weight.

Fully carbon bikes. Having a bike that is made up of 90% carbon fiber is something most people can only dream of. A bike made from this material will not only boast an amazing low weight but being strong enough for any type of racer. Its a very comfortable ride as well according to those lucky enough to have had a go.The only thing stopping your from being a carbon fiber racing machine is the cost. Most people can not even afford the shoes, let alone the bike…for the time being at least.
