The following list contains the basic characteristics and differences for the aforementioned types of MTBs plus 2 types of bikes that you didn't mention. Note that I've tried to summarise and "average" the characteristics of modern MTBs used today by amateurs and pros. So 9 kgs for XC bikes means that you can easily find 8 and 11 kg ones. Cross country (XC) ...

First off, when riding over rough terrain you should be hovering above your saddle, not sitting on the saddle. This holds whether riding a hard tail (no rear suspension) or riding a full suspension bike. If you are sitting you have less ability to move your weight around, and therefore less control of the bike. When sitting it is easy for a large bump to ...

If you can imagine a compromise between a mountain bike that is light weight and easy to pedal, versus one with that is strong and has lots of suspension travel to tackle rougher terrain you might get a diagram such as the one below. As we go from category to category we get heavier bikes that are harder to pedal, but that can handle rougher and rougher ...

First of all you need to tell the LBS (local bike shop) that the disk can be "fixed". Then you need to find another LBS because they are either amateurs or are simply trying to make you buy stuff that you don't need. You need to remove the oily disk from the bike and use a bike degreaser or alcohol on it to remove all oil. Rub with a clean dry cloth or ...

In german this is called "Hinterrad versetzen" -- "displacing the back wheel". I got to learn this in an mtb course I took a while back. If you can, try to find an instructor or other experienced rider to teach you. How to practice: Start very, very small and always wear full protective gear, i.e. a full-face helmet and vest in case you crash. You will ...

A lot will depend on the construction of the helmet. For example the basic material in the helmet will be some sort of sponge or foam which relies on its texture to absorb sudden impacts; does this degrade over time? For example, a loaf of bread gets its texture from the tiny air bubbles formed while rising and proving, but if left to prove too long, the ...

Vibram is simply a brand name for rubber soles made by Vibram S.p.A. of Italy. The actual composition of the rubber and the lug design used differs across their product line, with specialized compounds for hiking, industrial use, and for their "Five Fingers" barefoot running shoes. They began as a manufacturer for hiking shoes and were one of the first to ...

I don't think you are matching like for like and actually the price differential is quite small. The only fair way to compare two bikes is by looking at the frame only price. In this case I've been unable to find the frame only price for the Codeine (SingleTrack forum suggested £599 with Monarch R vs £225 for 456) so have used Santa Cruz instead: The frame ...

I'm told rear suspension is not a must have That's right, there is even a category in Down Hill races called "hard tail", for people with, well, hard-tail bikes. And they kick some serious arses with those bikes. What is the ride like without rear suspension, what do I lose? You have to pay attention where you put that rear wheel on. With a full, ...

I'm assuming this is your bike and you really mean that you've removed the fork from the bike as disassembling the fork isn't really something you do by mistake. The specs I found say that you've got a threadless stem and sealed bearing headset. This is easy to reattach. There are 3 or 4 bolts you need to be concerned with. One right at the top, that goes ...

Each type of racing is able to take advantage of certain team dynamics, and a few things are common across all disciplines. Specifics: DH/Super D: Downhill "teams" are more associated by sponsors and bikes than by riding together during a race. Since each run is done one at a time there's no drafting or anything like that. However, during track walks and ...

First, let's answer the first to questions together, as they are closely related. Does one lean with the bike? ...and... Does the bike stay more upright? Short answers are yes and yes in most cases. To elaborate, let's take a look at what you're trying to achieve when cornering. I found this image recently and I think it does a great job of ...

Simply put a bigger rotor provided better braking, and a four pot caliper provides better braking - better meaning more, and more control (Everything else being equal). For the same force between the disc and pads, a bigger rotor generates more torque on the wheel - i.e. more stopping force. It is running though the pads faster, generating more friction ...

Thru axles not only keep the wheel in place, they also strongly join the right and left dropouts together. This structurally reinforces the component either being it a fork or a rigid/suspended rear triangle. This simply makes the bike able to handle greater forces before failure, because it distributes forces between both sides of the structure. It also ...

Flat pedal specific shoes usually have a special rubber compound, such as Five Ten's sticky rubber or Shimano (and others) Vibram sole (used in hiking shoes as well). The goal of these special rubber compounds is to better stick to the pins of the pedals and are therefore usually softer so as to get a good grip on them. My personal experience with skate ...

Although this isn't explicitly part of your question, I'll go ahead and throw it in as it's one of the most important factors to consider in terms of increased suspension if you plan on pedaling your bike- the basic principle behind propelling a bike is to convert a mostly downward force (pedaling) into forward momentum (the drivetrain turning the back wheel ...

Ultimately there is no limit to what you can ride beyond your own skill. Many people say "too steep" is a cliff, but some riders just look at that like a drop and ride it anyway. You need to evaluate whether the places you are walking are because you lack the skill to ride them, the confidence to ride them, or improper equipment. Yes, you could ...

The S shape allows for: stronger head tube and bottom bracket welds without the need for gussetting. You'll find this on more trail focused bikes (such as AM, FR and DH). wheel clearance for long travel forks wheel clearance for the front wheel (ie. 29er's) Still allows for room for a water bottle within the front triangle

To answer your question title in very short: You don't have to fear them but some healthy portion of respect won't be wrong. The longer version: normally cow herds aren't really aggressive so it is quite safe to just go around the herd (if it blocks the trail) or pass them if they're close to the trail. Going right through the herd isn't a good idea in any ...

No. If you sit on the saddle then you become connected with the bike. That means that the next hit from the ground will be transmitted as is on you and you'll most probably go flying in an uncontrolled manner, usually nose heavy, and you don't want that. Apart from getting rest or pedaling, the only case where you touch the saddle is with your inner thigh ...

These are downhill MTB specific tyres. The extended side knobs will fully engage when cornering hard. By hard I mean: http://www.pinkbike.com/photo/6705085/ http://i129.photobucket.com/albums/p223/XCSlayer/DSCI4707.jpg The large gap between the center and the side knobs is mainly to reduce weight and to improve the mud management of the tyre (to not ...

I used to ride with skate shoes for a year and it was not good. I didn't know it. Generally skate shoes: bend more than MTB shoes so they'll not transfer all of your energy on the pedals do not have sticky soles so riding on rough trails may be harder and more dangerous due to the feet constantly changing position on the pedals Regarding non racing ...

Ask yourself this- would you buy a car off of Alibaba to save a few bucks, or would you fork over a little more money and buy a Honda/Toyota/whatever? Buy the name brand bike. If your Alibaba bike's headtube snaps off on a gnarly high speed descent, who's going to do something about it? Not Alibaba, and good luck getting the manufacturer from god knows ...

It's called an endo and you can start learning it anywhere right now (e.g in a parking lot). Don't try to learn turning endos or rolling endos at first. Here is a good how-to video (doesn't matter that it's on a bmx): ...

The answer to your question depends heavily on the infrastructure that is available to you, and the highest level of mechanical ability in your party. As another pointed out, you will want at least two pumps, multi-tools, etc. My wife and I do pretty challenging mtb tours with BOB trailers. We generally bring the following (subject to modification ...

What feels unstable when cornering on hard and smooth surfaces will turn out opposite on soft or structured ground. In this case the pronounced edge of the thread will bite into the soft ground or hook into the structure of hard ground which will give you a better side control than a thread that is just following the roundness of the tire. You can compare ...

Don't make any major mechanical changes to your bike the day before the race. If it ain't broke, don't fix it- at least not at the last minute. You will end up kicking yourself for it. Make sure you've had plenty of riding time on your bike's current configuration. Bring tools and tubes, but pack light. Bring a small/medium sized multi tool, a tube, ...

I ride a lot of trails where it is almost impossible to ride up and sometimes not even practical to push the bike up, and it is easier to carry. I've got a full suspension mountain bike with no space inside of the triangle, so it is not possible to shoulder it. And carry a bike on my back, rather than on a shoulder. Bottom tube is resting on my shoulders ...

The rotors cool very quickly (under 30 seconds for glove-meltingly hot to ambient). But the caliper can hold heat for some time, I'm very surprised at your 20min claim though - there's so little thermal mass. Modern disc brakes use an 'open' system which involves a reservoir with a metal diaphragm in, so when the fluid gets hot and begins to expand, the ...

disadvantages : more weight (more material, more oil) more energy required in order to pedal the bike is less snappier because it "eats" some of the terrain, so dirt jumping tricks (e.g 360s, backflips, frontflips) are harder than on bikes with less suspension some people believe that more suspension is not appropriate when learning to ride MTB and ...
