As (almost) always, the great Sheldon Brown has covered this particular topic. Standing while Cycling To Sit or to Stand? It is my belief that a great many cyclists stand up to pedal much more often than they should. I've often said: "If you find yourself standing to accelerate, on level ground, it is a sign that your gear is too high or that ...

To complement Neil Fein's answer, the rider's position is almost entirely controlled (given a particular rider) by the geometry of the bike. Compare the following bikes. In the first image of a hybrid bike, the saddle is slightly below the handlebars. In the second image depicting a road racing bike, the saddle is well above it, forcing the rider to lean ...

I think that this is a bad advice you've heard (by many?). For pedaling seated, the seat has only one position; the proper one. See How do I determine the correct position for my bicycle seat? for info on how to set it correctly. Regarding the flab thing, as far as I know touching your stomach with your thighs (or any other part of your body) will not ...

I think this relates quite nicely to motorbikes where you corner at very high speeds and I'll give a run-down of the techniques, why they are useful and how they apply, and how they might apply to cycling. So when turning left: You shift your weight over on the seat and tilt the bike left. This allows the centre of gravity to be slightly lower, aiding in ...

Standing up on a bike, especially when you lack fitness, is a good way to go "anaerobic." Put simply, that means your body is working so hard, it can't get enough oxygen. You can only do that for a short amount of time, which for most people is in the range of 10-30 seconds. Then the lactic acid build up in your muscles becomes too painful and you are forced ...

Boardman used what is known as the "Superman" position, as shown in this image. This position has been deemed to be against the rules by the UCI. Compare it to the position that Wiggins had on the bike, shown here. His arms are not as outstretched, and therefore it is not as aerodynamic. The superman position was first used in the hour record attempt ...

Yes there is one main trick, and some regular skills. The trick is: if you LOWER THE TIRE PRESSURE, any tire will float over sand like magic. It should not be so underinflated as to allow easy pinch flats, but the lower the pressure, the more marked the floating effect. There are just two limitations: If the tire is skinny (low volume) it might not be ...

Low seats provide clearance for more acrobatic body movements. This is essential for bunny hops and nearly every other trick which builds off of this skill. If you look at trials bikes they similarly have lots of clearance for the rider over the frame and the saddle. Since speeds are relatively low, and long distance riding is not the goal, pedaling ...

I agree with Hicks sentiment that the crank "giving" is more likely due to worn parts or misalignment. The crank would have to flex a lot to actually be responsible for ghost shifting, which would make it incredibly poor quality. Sheldon's article strikes me as cursory for "When Should You Stand"... Assuming you have the gearing for whatever you're riding ...

There isn't really any reason you can't stand while pedaling. If your drive train is not adjusted properly then they will experience skipping or mis-shifting. That's an entirely separate issue from being able to stand up and pedal.

I think most people find the bike-to-run transition quite difficult while the legs adjust from going in a circular motion to running. Particularly for longer distance courses. Here's an interesting article from a renowned triathlon athlete/coach: http://www.trainingbible.com/joesblog/2007/01/cleat-position.html The article discusses the merits of putting ...

I would suggest attaching the bars and doing some test rides. Is your bike, with it's aggressive geometry, stable when using them? Are you comfortable using them? Does this new position provide some relief, or is it just more annoying? I think you're the only one who can determine if they'll be an advantage to you. In general, I'd think the extra ...

What you're referring to is tucking, an act that's most easily done with drop bars - the curved handlebars with multiple hand positions you see on road bikes. The holy grail for some hardcore roadies (road cyclists) is the flat back, where the rider is tucked all the way forward, their hands on the lower part of the drop bars - the "drops". This is done so ...

Yes, a more aggressive stance requires a narrower saddle. Your pelvic bone is a fairly complicated structure, but there's basically a triangle that you sit on with a saddle. There's two bumps ("ischial protrusions") at the back end that take your weight if you're sitting with your back straight up (such as on a chair or the saddle of a cruiser or dutch ...

Of course, you will have less control over your bike if you don't hold the handle bars, especially if something unexpected happens (like a truck coming out of nowhere at full speed for example). Regarding sitting upright, you are very lucky to be able to keep your back straight like that, most people have a bad posture, and are not comfortable sitting ...

While it's true that your hips rocking indicates that the seat is too high, there is a different rule of thumb for knee pain related to the fore and aft position of the saddle. It's easy to remember: If your knee hurts in front, your seat is too far forward. If your knee hurts in the back, your seat is to far backward. The most important thing to ...

Your question is based on an incorrect assumption about how a bicycle makes turns. You say "...move my bottom to the left and this is sufficient to tilt the bicycle to the left." Unfortunately, what you are stating above is simply impossible in practice. A bicycle can be thought of as a vehicle that is "attached" to the surrounding environment by an ...

Regarding part 1: I'd start by raising the stack height a bit so that you lean on your wrists with less weight; your position will be more upright and less aerodynamic. Along with this, make sure your saddle is properly adjusted for height. More importantly you should try strengthening your abdominal muscles. With a stronger core you will be able to ...

As @Daniel has commented, and I agreed, you probably have a bike fit problem. We cannot be sure; the only way to find out for sure is to get a professional fitting done. Having said that there are still a few things you can try. While you say you try to adjust my hand positions, what positions do you use most? ... The Allez handlebar setup is one I ...

Pedaling while standing always takes more effort; we do it when we need the extra boost. When you were younger and rid[ing] a bicycle a lot, you were also fitter. I'm guessing you have had a sedentary job for a while, so now your whole system needs to build up again. This is, unfortunately in our modern world, normal. As with any strength / fitness program,...

This is most likely because you are putting your weight right on the median nerve (see first picture). Padded gloves may help a bit, but I suspect your hand position is more likely to be the problem. Other common hand nerve problems with riding can compression of the ulnar nerve, which will present itself as a different area of sensation than what you ...

I ride a pro racer XL BMX. They are built for speed. I keep my seat down for 2 reasons. all my pedaling is done standing up -- power is everything for a racer. My saddle is made of one material only -- composite material -- its like sitting on a steel plate. I only use it to coast on and relax -- and that is only after the race. However, If I ...

I have plenty of experiance in insanely soft sand. Before you leave : 29er, wide tyres, low pressure. BUT Low preasure costs when you get back onto hard stuff, as do insanely wide tyres. I set the bike up to go well on the hard stuff, and pay the price on the soft sections. On the track : Riding style is Weight Back, Very high cadence, great balance ...

There are some very good answers on here that go part way to explaining why there are something like 2000 saddles on the market. You did not mention whether you dress up for your daily commute with padded cycling shorts, however, your hybrid bike is designed for more general use, i.e. jeans and T-shirt, not the padded shorts. Hence it has a padded seat and ...

As others have said, just because the bike shop says it's a good fit, doesn't make it so. Their incentive is to sell a bike off the floor so they'll find the one that fits best and sell it to you. I got a custom fit and I have longer thighs than most people. This meant that to get the seat position right, I had to have my saddle further back from the pedals ...

I am not entirely sure this is really a bicycle question. It amounts to "I can't eat my usual lunch while riding a bike. What should I do". Fundamentally you can take two different approaches. First, you can modify your bike or riding style so the food you currently eat works. The most obvious solution is to fix the bike in place and add a table to the ...

It all depends on your saddle. As someone who has just been enlightened, some saddles are supposed to be pointed a bit nose up. Take the brooks flyer for instance, it is not the front that is supposed to be level. It is the back making the front point a bit upwards. I think of it less of a seat then a hammock. I have also had a saddle that was a left over ...

I have personally ridden and raced on many sandy courses and trails (e.g. Moab) and the best advice is to shift your weight back, relax and think about guiding rather than steering the bike. You will never be able to ride in a perfectly straight line, so get over it or avoid sand. Rather you need to let the bike move and shift around under you. You will ...

Changing from 50 to 65 (or the opposite) is definitely noticeable. And depending on your needs, switching may improve your riding. Switching from 50 to 65 will mean more pressure on the front end. That means better cornering (the front end will not wash out easily) and more stability on the downhill. Some people also mention that it'll improve climbing on ...

When it comes to turning on a bicycle, the two most important things you can do are: Keep your weight as close to the bike as possible. Simply put, your center of gravity should be as close to your bike as possible. If your turning left and sitting straight up with your torso haning off to the right of the bike the turn is going to be much more difficult ...
