Outings @Putrajaya 11th Oct 2009

Salam All.

Just done a Outings at Putrajaya this morning.

Route : Putrajaya (new route, kena mapping nih)
Time : 8am-11am
Mileage : 36.9km
Duration : 1 hour 30mins (extra 30mins at checkpoint Persint 11)
Cal Burn : 495 kcal
Participants : 27

Yang best kayuh dalam hujan..terpaksa stop kat Persint 11 sebab hujan lebat sangat.lecun giler.. kasut dah macam kapal selam bocor.. tak rasa penat langsung, maybe sbb sejuk dan tak berpelah.. dah rehat kat rumah baru rasa badan lenguh.

Kayuhan kali ni agak ok.. Maybe sbb mood ok, jam 5pagi dah warm-up 5km sekitar rumah. Gerek pon dah setting baru..

Pic will be uploaded later...

Cheers

Competitive Cyclist Fit Calculator

Nothing is really more important for creating a great cycling experience than matching yourself---your body, your goals, and your dreams---to the right bike. Some will tell you that there is one perfect fit for you and only one perfect bike. But we take a different approach. We know from experience that you can fit on a bicycle in a variety of ways and that each of them can be perfect for the many kinds of riding you want to do. We also believe that different bikes, sizes, and parts create different riding experiences and that there is more than one perfect experience. Undoubtedly, that is one of the beauties of great bicycles. We ride lots of different bikes and in different ways. Our experience tells us there are all kinds of bikes and ways to ride.

Because everyone is different, there is no one, single formula that creates the perfect fit. Different bikes and styles of riding create different fit options. We believe that there are different bicycle fits that will be perfect for you and different bicycles that will suit your needs, goals, and expectations. This means that we can tailor the fit to your style of riding and tailor the bike to fit you. Finding a great match between yourself and a bike isn't complicated but it is a matter of knowing what you really want and what you can expect from different kinds of bicycles.

Our fit methodology combines two - and if needed, three -- traditional approaches to fitting.

1. Body measurements and tested formulas. The numbers don't lie and are an important feature of your individual experience. We understand that measuring your body for the purpose of buying a new bicycle can be a daunting and confusing exercise. There are numerous techniques for determining your ideal size and fit, the most widely accepted of which is the "Lemond method", as set forth by Greg Lemond in his classic late-80's book "The Complete Book of Bicycling". The Lemond method provides the logic and the math behind virtually every bike fitting system you'll encounter. Whether your fitting is performed in a retail environment with tools such as Bio-Racer, the Fit Stik or the Fit Kit, or if you've derived your fit from a database-driven on-line fitting system, certain truths almost always hold true:

1. You will always be asked for your inseam, and you will always be provided with the following conclusions:
   1. Your center-to-center seat tube will equal (inseam x 0.65).
   2. Your center-to-top seat tube will equal (inseam x 0.67).
   3. Your bb-saddle height will equal (inseam x 0.883).
      
      
2. You will always be asked for a torso length and an arm length, and you will always be provided with the following conclusion:
   1. Your total effective reach (i.e. the sum of your top tube length plus your stem length) will equal (torso + arm)/2 + 4.
   2. Alternatively, instead of torso length, you might be asked for the length of your sternal notch to the ground. In this case, your total effective reach will equal (sternal notch – inseam + arm)/2 + 4.

Most folks rely on the Lemond method for one good reason: it's quite accurate. Over time, though, we became fixated on the two significant drawbacks of the process:

1. It computes your ideal seat tube measurement and initial seat height based solely on your inseam. Your femur length, however, can play a major role in determining your ability to produce maximum power in an adequately comfortable position. For example, if your femurs are long, you'll need a setback seatpost and a higher saddle position than someone with a smaller bone structure.
   
   
2. It offers only an overall effective reach measurement for your upper body. In other words, you won't be provided specific information about your top tube length and your stem length. Rather, you'll get the sum of an idealized top-tube-plus-stem measurement. Some riders are better suited to a combination of a long top tube and a short stem, some riders are the opposite, and some are in between.

When we made the decision to develop our Fit Calculator, it was specifically an effort to address these limitations. It became a bit of an obsession for us. We traveled to New York (more than once) to attend the weeklong Serotta Bike Fit Certification seminar, we logged countless hours fitting people on our Fit Cycle, we analyzed systems such as the Fit Kit inside and out, and we worked with the cycling consultants at the Australian Institute of Sport. We expanded the scope of biomechanical variables taken into account by the Lemond Method, allowing us to substantially improve upon its accuracy.

In terms of your upper body, our Fit Calculator takes into account both your torso length and your arm length, which sheds quite a bit of light on the inter-relationship between your top tube and stem. In terms of your legs, our Fit Calculator evaluates your femur length and tibia length independently, allowing it to provide you a more accurate assessment of both your frame size and initial seat height.

Is our system better than Lemond's? Not necessarily. But it's a more comprehensive evaluation of your anatomy, which in turn allows us to provide you with a greater amount of information for selecting and setting up your new bike. Think of it as a trustworthy second opinion to put alongside Lemond's tried and true system. After you enter your measurements, we'll supply you with fit and sizing data based on our Fit Calculator methodology. When you consider these numbers in combination with your sense of how well you fit on your existing bike, you'll be armed with virtually all of the data you'll need for sizing yourself to a new bike.

2. The experience of the master designer and fitter. While formula-driven fit systems are extraordinarily useful, there's a reason why stock geometry frames of the companies whose bikes we sell have made countless riders - many of them the most experienced, most demanding connoisseurs of the bicycle - so happy with the fit and the handling of, say, their Colnago, Pegoretti, or Pinarello. What's the secret? The years of wisdom of a master builder or fitter cannot be replaced by numbers or machine calculations.

3. Your positioning on your current bike. The optional third step of our Fit Calculator is to contact us via e-mail or phone to discuss your positioning on your current bike. Typically this sort of conversation is an excellent way to get a clear grasp of how your measurements might inform the output provided to us by the Fit Calculator.

In these ways we can combine facts, experiential input from you the rider, and the expertise we possess from years of fitting all types of cyclists and bodies. Ideally we can learn more about you, your cycling style, fitness and physical needs, as well as your plans for riding and what you can expect from a great bike. Our goal is to create a fit that matches you and the bike into a seamless relationship that meets your most realistic expectations as well as your dreams. Getting to know you will create confidence that you're making a great decision. We want to take the fear out of buying a high end bicycle and that means creating a relationship rooted in understanding, trust, and professional expertise.

Choosing the "right" bike means choosing a bike that keeps its end of the bargain. If you are planning on racing or enjoying fast club rides then the bike should perform to match your expectations. If you are looking to ride long days or face challenging climbs that test your endurance, then the bike should match your goals. The truth is that many bikes can perform well under all sorts of conditions and in different scenarios: what you need is one that matches your needs.

We are sometimes mistakenly led to believe that there is only one "right" size for each individual. Actually there may be more than one size of the same bike model that works well for you and the "right size" depends more on how you choose to ride. We'll help you make the best choice for you and your riding style. It's certainly possible to find one bike that serves you well under a variety of circumstances but this means coordinating the best match between rider, bike, and fit. Even if you have only one bike there can be more than one great fit on that bike. We know this from hard won experience.

We need 7 core pieces of information in order to calculate your optimum frame size and initial position. You'll need the assistance of another person to make the most accurate measurements possible. And don't be afraid to take each measurement 2 or 3 times and average the measurements together. Please keep in mind that the accuracy of the Fit Calculator is strictly a function of the accuracy of the information you provide! We've discovered over time that if there is a large variation between the results from the Lemond method and the results from the Fit Calculator, it's a strong indication that the body measurements you've provided are inaccurate. Please take your time and be as meticulous as possible!

Input

Wear your cycling shorts, and take the measurements in bare feet.

1. Inseam
   Set your feet approximately 8" apart and straddle a straight edge – something like a square or a 2' level is ideal. Put as much pressure on your crotch as you feel when sitting on your bike seat. Measure the distance from the top of the level to the ground. Alternatively, mark the wall, then step away and take the measurement of the mark to the ground. And whatever you do, please don't use the inseam measurement from your Levi's! Pants inseams are at least 2" shorter than your actual inseam.
   
   
2. Trunk
   Sit on a stool with your back straight and your pelvis hard against the wall. Make sure your back is straight and your pelvis is against the wall. Place the level on top of your AC (Acromioclavicular) joint and against the wall. The AC is the bony bump on top of your shoulder. Measure from the bottom of the level to the top of the stool. Measure both sides of your body and average the measurements.
   
   
3. Forearm
   Remain seated and hold a cylindrical object (a magic marker is ideal) in your fist. Lower your arm so that it is to your side and extend your forearm ahead of you. Keep the object in your hand perpendicular to your forearm, and measure from the center of the object, which should fall in line with your knuckles to the boney protrusion at your elbow pivot.
   
   
4. Arm
   Continue to hold the cylindrical object and extend your arm in front of you, holding your arm parallel to the ground. Try not to allow your shoulder to come forward. Make sure that the object in your hand is perpendicular to your arm. Locate the Pivot of the arm to shoulder point and measure from this point to the center of the object, which should fall in line with your knuckles. Measure both arms and average the measurements.
   
   
5. Thigh
   Sit on a stool again making sure your back is straight and your pelvis is hard against the wall. Make sure your femur is parallel to the ground and your tibia is perpendicular to the ground. Place the level across the front of both of your kneecaps, then measure from the inside face of the straight edge to the wall. Take this measurement from both legs, then take the average.
   
   
6. Lower Leg
   Remain seated. Place the level across the top edge of your kneecaps (where they connect to the bottom of your inner quadriceps muscles). Measure from the bottom of the level to the ground.
   
   
7. Sternal Notch
   Stand up against the wall. Set your feet approximately 8" apart and straddle a level. Find the sternal notch in your neck – it's the bony "V" immediately beneath your Adam's apple. Measure the distance from the apex of the notch to the floor.
   
   
8. Total Body Height
   Remain standing against the wall with your feet 8" apart. Set a hardback book or a ruler on top of your head and make sure it touches the wall without sagging. Mark the wall at the point where the book or ruler meets your head. Measure from this point to the floor.

Output

1. Seat Tube Range C-C
   Your new bike's seat tube height should fall within this range. "Center-to-Center" signifies the length of the seat tube as measured from the center of the bottom bracket spindle to the midpoint of where the seat tube intersects the top tube. The seat tube height is most important as it relates to your head tube. If your seat tube is too short, your head tube will almost certainly be too short. This results in too low of a handlebar position placing an inordinate amount of stress on your neck and back. For this very reason, if you feel as though you could go with either of two sizes, going with the bigger frame is normally advisable. Please keep in mind that many frames come with a sloping or "compact" frame geometry in which the C-C seat tube measurement is artificially short. In the case of compact frames, you should primarily focus on the top tube measurement.
   
   
2. Seat Tube Range C-T
   "Center-to-Top" signifies the length of the seat tube as measured from the center of the bottom bracket spindle to the top of the seat tube where it intersects the top tube. Colnago is the one brand we sell that sizes their bikes according to C-T instead of C-C, so pay close attention to this measurement range if your primary interest is in a Colnago.
   
   
3. Top Tube Range
   This measurement is along the top tube, from the midpoint at the seat tube to the midpoint at the head tube. No single piece of frame geometry has a greater impact on comfort than your top tube. If you plan on paying attention to one measurement and one measurement only, make it this one. Keep in mind that we do not measure the actual top tube on bikes with compact frame geometry. Rather, we use an "Effective Top Tube" measurement – an imaginary line drawn parallel to the ground along the length of the top tube.
   
   
4. Stem Length
   This measurement indicates your ideal stem length. It takes into account that your stem will be flipped to its flatter angle (e.g. 80° for Deda, 84° for Ritchey).
   
   
5. BB-Saddle Position
   This measurement is along the seat tube, from the center of the bottom bracket spindle to the top of the saddle. It is an ideal starting point for saddle height. Given the varying differences of cleat and pedal heights, and given the varying differences in the thickness of saddles, the BB-Saddle position has a broad range of 2cm.
   
   
6. Saddle-Handlebar
   This measurement ties together your choice of stem length with your saddle setback. It is measured from the nose of the saddle to the near edge of your handlebar. Keeping within this range will assure that you don't accidentally push the weight balance of your bike either too far forward or backward.
   
   
7. Saddle Setback
   This measurement is primarily a function of your femur length. The longer your femurs, the further your saddle needs to be behind the bottom bracket in order to allow you to produce power. If you sit too far forward (or too far back) you can over-emphasize certain muscles and joints, which robs you of power and can potentially cause you injury. Saddle setback is measured by dropping a plumb bob from the nose of your saddle and measuring how far behind the center of the bottom bracket it falls. This is not to be confused with the setback measurement of your frame, which is a measurement taken by dropping a plumb bob from the center of your seat tube/top tube interface, and measuring how far behind the center of the bottom bracket it falls.

Mountain Bike 101 - from Shimano

Mountain Bike 101 From Shimano

How do I choose?

Because riding styles and equipment have evolved to suit different terrain, deciding which bicycle is right for you will be easier if you know what type of terrain you intend to ride.

A common misconception is that a new rider needs more suspension because of the added control. While the added suspension may instill confidence in some technical sections, often time the relaxed geometry is not suited to less experienced riders.

On the other hand, it is just as hard to avoid the temptation of the ultra-light bike. The benefits of light weight are undeniable, but a novice rider will find XC racing bikes can be difficult to control when the trail gets rough.

XC Racing Bikes

Often called Cross Country bikes, XC Racing bikes are designed to tackle a mountain from the bottom. Lightweight and efficient, XC bikes often sacrifice comfort and control as luxuries you can’t afford when racing to the top.

XC bike frames are either hardtail or short travel, semi-active suspension designs. Long and low, XC bikes put the rider in a stretched out position. Best suited to gradual terrain, XC racing bikes are popular in areas without a lot of rocks and roots and among competitive riders.

If your idea of mountain biking is fitness and endurance you may want to consider a XC Racing bike. If you consider the best rider the one who made it to the top first, then your choice is made.


XC Trail Bikes

Often called all-purpose, XC Trail bikes are what most people think of when they hear the phrase “mountain bike”.

XC Trail bikes are designed to climb with control and comfort and descend with speed. With active suspension, knobby tires and low gearing the XC trail bike is slightly less efficient than an XC Racing bike but can be more enjoyable to ride downhill. As terrain gets steeper, trails tend to get rockier and the ultra-light XC Racing bike may ride roughly, but the XC Trail bike is right at home.

If you like the idea of challenging yourself on a rocky climb, enjoy extended singletrack descents and want to battle it out with your friends going uphill or down, An XC Trail bike may be for you.

All-Mountain Bikes

Some riders just need more. As adventures get longer and trails more remote, many riders see increased value in reliability and downhill control.

The bigger tires, plush suspension and powerful brakes of the All-mountain bike are an insurance policy against accidents and mishaps and can be just plain fun to ride. With geometry suited to steep terrain and small drop-offs All-mountain bikes can inspire confidence, however, on more mild terrain they can feel sluggish.

If you are an all-day adventurer or ride harsh trails you may be an All-mountain rider.

Freeride Bikes

Freeride bikes are designed to ride the most extreme types of terrain. Steep chutes, large rocks and roots, big jumps and drop-offs, and just about anything else, natural or man-made, that you can imagine.

With only the occasional concession made for even the thought of riding uphill, freeride bikes are mountain biking’s version of monster trucks. Blurring the line between bicycle and motorcycle, bikes with eight inches of rear wheel travel, three inch wide tires, and eight inch diameter brake rotors are commonplace.

If you are attracted to the challenge of going big and see mountain biking as a source of individual expression, Freeriding will appeal to you. And what does any extreme athlete need? Well, a Saint to watch over him, of course.
