Le pido disculpas a ghost si malinterprete su comentario. No suelo ser asi. Y al bakalao, es lo q he notado de diferencia entre mis bicis y no estoy hablando d teorï¿½a.

Y antes de q alguien diga q no se pueden comparar las hardtail con las full, pues eso lo sï¿½. Por eso es q me opiniï¿½n es basada en bicis full d mas o menos el mismo peso y travel en la suspensiï¿½n trasera Pq es lo q Tengo y corro, Pq no tengo bicis hardtail. Cool

Nope!!! No Hubo Cinismo tampoco intenciones de formar una discusiï¿½n. Todo fuï¿½ un pequeï¿½o malentendido. Me gustan las crï¿½ticas que haces Carlitos, son muy certeras.

By the way!! no tienes que disculparte muchachï¿½n, no pasï¿½ nada. Soy un chamaco tranquilo y humildï¿½n, me dï¿½ cuenta que hubo un malentendido e inmediatamante te ï¿½ba a aclarar que nada negativo pasaba por mi mente. Henry se me adelantï¿½ jejejeje con su estilo jejeje. gracias Henry! esta todo bajo control.

Pa'lante chikos!! Razz

Dios les bendiga en el dï¿½a de Reyes.

Ending The Debate: 29er vs. 26" Mountain Bike

With the widespread adoption of the 29er mountain bike in manufacturing and the mountain bike community, the growing debate of 29er vs. traditional 26″ mountain bikes is getting hot amongst riding groups. If you are in the market to upgrade your current mountain bike or get into the sport, your options are wider than ever which is a good thing for the sport but can be debilitating when looking to purchase a new rig.

There is no ï¿½right answerï¿½ for every mountain biker, so letï¿½s take a look at the 26″ vs. 29er mountain bike debate and see where it shakes out in my opinion. This topic is probably the most debated in the industry, so you will find that every rider has what they think is the right answer for you (typically what they bought).

The 29er Mountain Bike: What is the big deal?

Before we get into what will work best for you, letï¿½s take a look at this larger wheel size and see how it affects the mountain bike in a general way.

What does a 29er do well?

Rolls over rocks and roots easier due to the wider circumference.
More distance covered per pedal revolution.
Higher air volume in tires smooth out ride.
The larger diameter wheels of the 29er mountain bike can create the sensation of having an 1″ more travel than the bike is specï¿½ed due to the larger air volume and larger contact patch with the ground. For this reason, it has become the go to size for much of the hard tail and shorter travel mountain bikes in the industry. The racing world has really embraced the larger wheels size for these benefits it brings to the trail.

What are the drawbacks of a 29er?

Large size equals larger weight.
Harder to maneuver in tight, twisty single track.
Longer travel (5.5″ and higher) 29ers feel REALLY big.
Sizing and geometry issues with smaller riders.
Larger radius needs stiff wheel build and fork to prevent deflection.
Just as with any big change, it is not all good news. While the true 29er zealots will probably tell you these things are not true, the reality is that you are adding bigger wheels to the mountain bike than traditional 26″, so there are going to be negative side affects that go along with the positive changes.

26″ vs. 29″ Wheels: Which is right for me?

When you are taking a look at the 26″ vs. 29er mountain bike, there are several personal questions you need to ask yourself as you make your decision. As with all things, there is no right answer that fits all people. How you ride your bike and how you want it to react is the most important factor when making this decisionï¿½not what your friend bought and says is the best.

So here is how I see it shake outï¿½

How tall are you?

As the distance from your head to the ground increases, the 29er wheel size actually becomes more proportional to your size. Riders in the 6 foot and up crowd that are looking for a XC to light AM mountain bike should test ride a 29er just to see how they like it. You might find that it fits perfectly and you have finally found a bike that feels like it actually fits. Shorter riders in the 5ï¿½6″ range and lower will need to take a serious look at geometry and test ride different frames as they might find the bike feels too big or isnï¿½t able to maneuver as well. I have known shorter riders that have loved the bigger wheel size, but that is typically in hard tail applications.

Taller Riders: Yes
Shorter Riders: Maybe
How much travel are you looking for?

While the argument that a 29er ï¿½adds an inchï¿½ of travel is almost true in theory, there is a big difference in 140mm forks and 160mm forks in mountain biking. The thicker stanchions and construction make a huge difference for riders looking to get into the more technical side of riding. If you are in the market for a 140mm or 160mm travel mountain bike, a 120″ travel 29er is not going to give you that same stiffness and confidence from a bike build and component standpoint. Also, as you move up in travel the bike feels bigger and when you add in the larger wheel diameter, that gets multiplied and can hold you back in slow tech and DH situations.

However, if you are looking at lighter 130mm to 140mm travel 26″ mountain bikes and you are taller, the 120mm travel 29er might be a great option. It will roll over technical rocks and roots on most single track easier and you will still be able to keep the overall bike weight under 30 pounds in most cases.

In the short travel and hard tail mountain bike market, the 29er mountain bike has almost completely taken over.

HT and 100mm travel and under: Yes
120mm to 130mm: Yes
140mm: Maybe
160mm and up: No
What type of trails do you ride?

As mentioned before, 29er mountain bikes do take more to maneuver through tight single track. If all of your riding is filled with tight turns in trees, you will want to try out a 29er on your own local trails before making a decision. On the other side of the spectrum, if your trails are more open and rocky, the 29er wheel size can really excel and bring more speed as you can hit sections faster.

Do a lot of racing and forest service road riding? A 29er is almost a no brainer in those situations. If you donï¿½t believe meï¿½just try to keep up with a 29er rider on a FSR. This adds up with the shorter travel and hard tail mountain bike market.

Tight and twisty: Maybe
Open and rocky: Yes
Racing and FSR: Yes

What do I personally use? 29er or 26″?

When I spec out my personal mountain bikes given trail conditions, this is how everything lays out for me personally given my specs. I would describe my riding style as technical. I like to find the nasty lines possible and make them ridable at speed. For this reason, I typically like to ride mountain bikes with big forks and more travel, but I also like to dip into the XC and race side every now and then as I have a background in those applications. At 6ï¿½1″ tall, I fall into the taller side of the sizing spectrum in between large and x-large. To fit my need to find all tech riding, I am on large size mountain bikes to keep the bike easier to move in slow tech.

Singlespeed and Hard Tails: 29er
Short Travel Race Bikes (100mm and under): 29er
Trail bike (140mm and higher): 26 inch
As of right now, I have not found a 29er mountain bike that has been able to handle what I want to throw at a 140mm travel or higher mountain bike. It has not been agile enough and the 32mm stanchion forks mated with higher radius wheels are not built to withstand the abuse. Given the specs of 29ers, I do not see this changing for me as a rider.

On the shorter travel end, there are a lot of advantages of the larger wheel size that have made a couple of 29ers the fastest bikes I have ever ridden for those applications. I doubt if I will ever go back to 26″ wheels for anything under 100mm worth of travel.

What is the right bike for you?

As you take a look at all of these specs, you have to look inward at your body type and riding style to see which wheel size will be the best option for you. There is no right option for everyone and the 29er wheel size is not going to take over the mountain biking industry like a lot of the Kool-Aid drinkers are trying to say. The larger wheel diameter does have some serious advantages in certain situations, but it also does not work for others.

The best optionï¿½test ride your top 26″ candidate on your local trail and the top 29er candidate if they are available. If they arenï¿½t, find the closest substitute. At the end of the day, you are the one making the investment in your mountain bike and you will be the one riding itï¿½not everyone else that is trying to inject their opinion in your buying decision.

Actual measurments using same gearing. lengths are how much further a 29″ wheel rolls per 1 revolution

22/34 5″
32/34 8″
44/34 9″
22/11 19″
32/11 20″
44/11 33″

Bicicletas 29er. ï¿½Cuï¿½l es el problema?

Antes de comenzar a explicar quï¿½ bicicleta es mejor para cada uno de nosotros, echemos un vistazo a este tamaï¿½o de rueda mï¿½s grande y veamos cï¿½mo afectan estas pulgadas a una bicicleta de montaï¿½a de forma general.

Ventajas de una 29er

1. Pasa por encima de las rocas y raï¿½ces con mï¿½s facilidad debido al diï¿½metro mï¿½s grande de la rueda.

2. Tiene una mayor distancia recorrida por vuelta de pedal. Es decir, a igual cadencia, mayor distancia recorrida.

3. Hay mayor volumen de aire en los neumï¿½ticos. Las cubiertas de 29 pulgadas tienen una mayor superficie de contacto con el suelo debido a su mayor diï¿½metro, y por esta razï¿½n los fabricantes de bicicletas de paseo han convertido esta medida en un estï¿½ndar para este tipo de bicis. En el mundo de la competiciï¿½n las ruedas mï¿½s grandes tambiï¿½n aportan muchos beneficios en las carreras, y es muy fï¿½cil ver este tipo de modelos en la mayorï¿½a de competiciones de Mountain Bike.

Inconvenientes de una 29er

1. Un mayor tamaï¿½o es igual a un mayor peso, si hablamos de componentes de gama equivalentes entre ambas versiones de rueda.

2. Mï¿½s difï¿½cil de maniobrar en pistas estrechas y reviradas.

3. Tiene un recorrido mï¿½s grande,por lo que las 29er parecen gigantescas.

4. Por tamaï¿½o y geometrï¿½a, una 29er no es muy adecuada para ciclistas de estatura baja.

Como todos los cambios, existen ventajas e inconvenientes. Probablemente los fanï¿½ticos de las 29er creerï¿½n que los inconvenientes no son tales, pero la realidad es que en una bicicleta de montaï¿½a 29er las ruedas son mï¿½s grandes y por lo tanto, si existen cambios que son positivos con respecto a una 26", pero tambiï¿½n existen otros aspectos negativos.

26" vs. 29er. ï¿½Cuï¿½l es la mejor para tï¿½?

A la hora de elegir entre una bicicleta de montaï¿½a de 26" o una 29er, existen varias cuestiones que hay que plantearse antes de tomar una decisiï¿½n. Como todas las cosas, no hay una respuesta correcta que se ajuste a todas las personas. ï¿½Cï¿½mo usamos la bicicleta y cï¿½mo queremos que reaccione? ï¿½sta es la pregunta que debemos hacernos y no debemos guiarnos por lo que se dice que es mejor o por lo que nuestro amigo ha comprado hace poco.

ï¿½Cuï¿½nto mides?

En una 29er, la distancia desde nuestra cabeza hasta el suelo aumenta. Como el tamaï¿½o de rueda es mï¿½s grande, en realidad llega a ser mï¿½s proporcional a nuestra estatura. Los ciclistas de mayor estatura deberï¿½an probar a montar en una 29er, puesto que probablemente sean los mï¿½s indicados para este tipo de bicicletas. Quizï¿½ encuentren una bicicleta que se ajusta perfectamente a su cuerpo y se adapten a la perfecciï¿½n con ella.

Los ciclistas mï¿½s bajos o de menor estatura, tendrï¿½n que valorar mï¿½s seriamente el tamaï¿½o de los cuadros de una 29er, asï¿½ como buscar la geometrï¿½a del cuadro que mejor se adapte a su estatura. Podrï¿½a darse el caso de que la bicicleta nos quede demasiado grande y no seamos capaces de manejarla correctamente. Lo mejor es probar a montar en diferentes modelos de bicicletas 29er, hasta encontrar (si es posible) la que mejor se adapte a nuestra talla.

Ciclistas altos: Sï¿½

Ciclistas mï¿½s bajos: Tal vez

ï¿½Quï¿½ recorrido necesitas?

Si bien el argumento de que una 29er solamente aï¿½ade una pulgada en el recorrido de la suspensiï¿½n es casi cierto en teorï¿½a, en la prï¿½ctica existe una gran diferencia entre horquillas de 120, 140 y 160 mm. de recorrido. Las barras mï¿½s gruesas y la construcciï¿½n mï¿½s robusta de las horquillas de gran recorrido pueden marcan una gran diferencia en ciclistas aficionados a los descensos y el FreeRide.

Si buscamos un recorrido de 140 o 160 mm. en nuestra suspensiï¿½n, una bicicleta 29er de 120 mm. de recorrido no conseguirï¿½ aportar la misma rigidez y confianza en su construcciï¿½n desde el punto de vista de los componentes. Ademï¿½s, a medida que aumentemos el recorrido, una bicicleta de montaï¿½a 29er se siente cada vez mï¿½s grande y menos manejable, por lo que no es muy aconsejable para los amantes del descenso y FreeRide extremo.

Sin embargo, si buscamos un recorrido de entre 120 y 140 mm. en una bicicleta de 26 pulgadas, una 29er de 120 mm. de recorrido puede resultar ideal para nuestros propï¿½sitos. Si tenemos una estatura media o alta, con una 29er pasaremos por raï¿½ces y piedras mï¿½s fï¿½cilmente, sin que con ella aumente el peso de nuestra montura considerablemente.

En recorridos cortos de 100 mm. y menos en la suspensiï¿½n o en rï¿½gidas, las bicicletas de montaï¿½a 29er son totalmente aconsejables.

Rï¿½gida y 100mm. de recorrido o menos: Sï¿½

De 120 a 130 mm. de recorrido: Sï¿½

140 mm. de recorrido: Tal vez

160mm. de recorrido: No

ï¿½Quï¿½ tipo de senderos sueles hacer?

Como menciono anteriormente, las bicicletas de montaï¿½a 29er son mï¿½s difï¿½ciles de maniobrar en senderos estrechos y revirados. Si solemos salir por rutas llenas de curvas y ï¿½rboles, es muy recomendable probar una 29er en esas mismas rutas antes de tomar una decisiï¿½n.

Por otro lado, si nuestras rutas suelen ser mï¿½s abiertas y con caminos pedregosos, el tamaï¿½o de una rueda 29er realmente puede marcar grandes diferencias y hacernos circular con mayor velocidad, sorteando piedras y raï¿½ces con mayor facilidad. Solamente tenemos que intentar seguir una 29er en este tipo de terreno: sudaremos de lo lindo.

Estrechos y revirados: Tal vez

Abiertos y pedregosos: Sï¿½

Racing y rï¿½pidos: Sï¿½

ï¿½Cuï¿½l es la bicicleta ideal para tï¿½?

Una vez que hayamos echado un vistazo a todo lo anterior, solamente queda mirar hacia nosotros mismos y en virtud de nuestra estatura y estilo de conducciï¿½n, decidir quï¿½ tamaï¿½o de rueda serï¿½ la mejor opciï¿½n para nosotros.

No hay ninguna opciï¿½n adecuada para todos y el tamaï¿½o de una rueda 29er tiene algunas ventajas muy importantes en ciertas situaciones, pero tambiï¿½n sus inconvenientes.

La mejor opciï¿½n: probar a montar el modelo de bicicleta que nos gusta en 26" y despuï¿½s probar la candidata en 29er si estï¿½ disponible. Si no es asï¿½, buscar un modelo semejante de 29 pulgadas y probarlo en las mismas condiciones. Al fin y al cabo, nosotros somos los que vamos a invertir nuestro dinero en una bicicleta nueva y debemos asegurarnos que se trata del modelo ideal para nuestro estilo.

Respeto sus opiniones y preferencias, pero en los 30 aï¿½os que llevo compitiendo en bicicletas; el cambio en la bicis que mayor que a impactado el desempeï¿½o de los corredores es el PESO.

si algunos de los 26" (antiguos) que tenga una Scott Spark en carbon medium en buen estado se la cambio por mi 29" carbon SuperFly/Trek super equipa en 24 lbs. Enviame un PM.

como dijo de los anteriores: "para los gustos.. los colores".

Prefiero mas la corrida agreciba, que los caminos abiertos donde la 29 se siente SUPER y definitivamente puedo mover mejor la 26".

Por cierto no tengo IPhonoe.... :)
