So you have decided to learn guitar, and went out and bought an instrument. You know a handful of chords already, and can strum and sing a few easy guitar songs. But all of a sudden you come across a song that's out of your vocal range and therefore requires a capo (pronounced kay-po). What the heck is a capo, how does one use it? Read on to learn how.
A capo is a metal bar that is clamped across the fingerboard of all six guitar strings, which raises the pitch of all the strings uniformly. It functions much like the nut of the guitar, except that it is movable. It essentially lets you use the same chord shapes to play in different keys.
Lets say that you only knew the chords G, C, and D. Play a G chord on the guitar and a G chord on the piano and two will sound fine together. However, what if the piano wants to play the chords, A, D and E. Put a capo on the third fret, and then use the same G, C, and D chord forms. Though it will look like you are playing in the key of G the chords will sound like they are in A because the capo has raised the pitch of the strings due to it being clamped at the third fret. Make sense?
Capos come in a few different configurations, lets take a look at them.
Trigger Capos
Trigger capos are made by companies like Kyser and Dunlop. They maintain clamping pressure by a powerful metal spring mechanism. The tension on these capos is not adjustable; you open the capo, place it where you want, and it clamps down. As a result they will sometimes pull all the strings sharp. They are very fast to use and place on different frets, just squeeze it with one hand, move it, and let go. A lot of guitarists that change capos mid song like them for that reason. They are a bit bulkier than other types, so if you want a slim unobtrusive capo this may not be the one for you.
Adjustable Tension Capos
Adjustable tension capos allow you to vary the amount of tension that is placed on the strings when you clamp the capo down. Units like the Shubb Original and the John Pearse Ol Reliable are examples of adjustable tension capos. They use a screw mechanism on the back to vary the clamping tension. Thus it's very easy to find the exact amount for your particular guitar neck that will keep the strings clamped down, but not pull them out of tune. The John Pearse capo is nice because it can be hung between the fingerboard and the headstock when not in use. This is very useful if you tend to lose capos at a gig.
Hi Tech Capos
Over the past few years there have been a couple capos take a cool high tech approach. The G7 capo is the most notable of these, winning several awards for its design. It is variable in clamping pressure, but uses a hub and spring system instead of a tension screw. You squeeze it down onto the guitar neck and it clamps down with as much pressure as you give it. Pretty neat. Planet Waves makes a capo called the NS, for Ned Steinberger, who helped design it. It is very slim and unobtrusive. Tension adjusted by a small dial in the back. You place it in the desired location, and tighten the dial till it clamps down with enough pressure to keep the strings in tune.
Depending on the style of music you want to play, some capos may work better than others. So head on down to your local music store and check a few out.

Using On-Board Cameras For Track Days
Track days are becoming increasingly popular both for people wanting to experience high speed motoring in top of the range cars or simply for others wanting to push their own bikes and cars to the limit in a 'safe' environment. No extreme motoring experience would be complete without a DVD to demonstrate your Lewis Hamilton-like skills to family and friends. If this is a must-have for you it is worth checking out what is on offer at your track of choice before the day itself. Some tracks will allow you to take your own on board or helmet camera, others will allow you to film providing you sign a disclaimer and some have an absolute ban. There are four main scenarios:
Someone at the track may already be on hand to offer their services to provide you with a camera set up to film your experience. This service generally includes mounting the camera, handling all the filming and burning the video to a DVD. You should expect to pay between £25-£35 for this type of package.
The second and popular option is to take your own helmet camera with you. Most of the regular tracks around the country are perfectly happy for people to use a helmet camera or on-board camera but they will check to ensure that the mounting of the camera is secure.
Thirdly, the higher profile tracks such as Silverstone or Brands Hatch will require you to sign a disclaimer promising that the footage is for private use only and won’t be uploaded to the web. At these tracks you’ll also need to have the permission of the race officials to take the camera out and again they will want to check that it is mounted securely.
A handful of tracks are completely against having any in-car, on-board, or helmet mounted action cameras out on their tracks. Unfortunately this includes the legendary Nürburgring where they will give you a life time ban if they catch you trying to sneak a camera onto the track.
Choosing a camera
If you are going to be enjoying track days fairly often or if you would also use the camera out on the road or for various other sports, then it may be more cost effective to buy your own. A starter camera retails from just £99 and for £299 you’ll be able to get a top spec, HD action cam. The most popular cameras and the best for filming track days and other motorsports are on board cameras.
Mounting
There are various ways to mount an action camera to optimise results, dependent on both an individual's preferences and the specific sport. Within the field of motorsports, correct mounting of the camera is a vital consideration as track day officials won’t allow an action camera which isn’t mounted securely. Whilst industrial strength adhesive has been tested at huge speeds, that simply won't cut it with officials. You’ll need to have a purpose built camera mount which either fits around or clamps onto your handle bar or forks. Panavise suction mounts are also acceptable on most tracks which is good news as the suction mount lets you position the action camera on to your helmet, the bikes tank, the outside or inside of your car or pretty much anywhere else where you can find a smooth surface.
Each track and race day official will have its own views on the best and safest way to use in-car, on-car, on-board, or helmet mounted action cameras to film your race day. You can rent them at the track or bring your own, in which case you need to be sure to have a secure mount so that you’ll be able to take it onto the track to capture your experience.

road bike stem-handle bar quere?
have a miyata roadbike,frame little small for my long legs. if i get a stem extender,i'll be o.k. / now when i loosen the head of the stem ,part that contacts and wraps around the handle bars/ will the bars detach from stem, or do i have to take bar tape off brakes off scwirm the bars through the stem clamp?any help appreciated. basically i want to detach the bars from the stem. will the stem clamp point spread to pull bars away.
You'll need to remove the brake lever and bar tape from one side of the handlebar.
If you try to spread the clamp, you'll ruin it.
If you're trying to get a bit more stretched out on the bike, you'll either want to use a longer stem or insert the quill deeper into the steerer tube...or a combo of both. If there's much of a difference in length, you may notice the bike's handling becomes a bit slower.
