With the invasion of bicycles on the streets during the pandemic, many doubts also arose from those who had been away from bicycle pedals for years.
Over the past few years, the bicycle scenario has changed a lot, especially in relation to the size of bicycles, in the more specific case of the 29 rim bicycle.
Bigger than the traditional 26 rim bikes that dominated the market years ago, the 29 rim bike has become the object of desire for older cyclists and with advances in competition, developments in sport and media, they have become the focus.
As a result, the market has enormously absorbed the 29-rim bicycle, making even those who are returning to or starting out in the sport opt for it. But of course, many questions also arose with this, especially on how to choose the rim 29 bike and that, we help you as you see below:
Check the frame size of the bicycle rim 29
Regardless of the size of the bike, knowing how to check this measurement is essential so that the bike\’s compatibility in relation to the cyclist is accurate , helping to achieve better performance and greater comfort when pedaling.
This factor does not change the modality or intensity of use for cyclists and is extremely important, as it directly interferes with the physical condition, since cycling with larger frames can cause discomfort, pain and injury.
As well as larger frames, smaller frames can also cause these problems, besides, of course, that, in both situations, they compromise the performance, comfort, health and safety of each cyclist .
In each brand there are differences in relation to the size of the bike frame and, therefore, it is important that when you find the bike you want, this information is passed on to you, especially due to the specifics of each bike model .
In general, the vast majority of rim 29 bike brands have 4 frame sizes for their 29 mountain bikes .
These sizes slightly modify the geometry in relation to height and length measurements, but the angles tend to be the same so as not to compromise comfort and handling when pedaling, regardless of the rider\’s height .
The sizes start on the 29 rim bikes with the measure aimed at smaller cyclists in size P or also known by numbers, in this case, 15 or even 15.5. In this case, the average height indicated for these tables is for people between 1.65 and 1.71m tall.
Already the frames with size M or also called 17 are indicated for cyclists with the most common average height of the population and so is the frame size most sought by varying the cyclists height of 1.72 to 1.76M height.
Note the pictures above and to the side where the difference in relation to the top tube is shown – the top bar of the frame of the bicycle rim 29.
In these two photos it is possible to see the difference in relation to the position of the cyclist who has 1.68m in the top tube and also in the angle of the arms.
Another frame that is in great demand by the vast majority of male cyclists are the size 19 or G frames. They are indicated for taller cyclists with an average height between 1.72 and 1.76 m.
Finally, the frames of bicycle rim marks 29 mtb size GG or 21 are aimed at cyclists with heights between 1.83 and 1.90 m. There are still more frames above these for rim bikes 29 , but they are less common to see and can be ordered from manufacturers.
For those who ride speed , that is, in road cycling, the numbering of frame sizes of bicycles differs a little. The speed charts have numbers ranging on average from 46 to 58 , varying a little more or less according to the manufacturers.
In the photo on the side a comparison with a 29 GG rim bike, or size 21. Note that the cyclist almost has to stand on tiptoe to be able to position himself on the bike .
But in all cases and even with different geometries in the modalities, the numbering and size of the frame are fundamental for you to pedal and always keep an eye on.
Take a look at the bike group
With the frame size in the right measure for you, adjusting other measurements is essential and for this the bike fit helps a lot in the small details of lengths and angles of the table, handlebars and seatpost .
But another very important point is the transmission of the bicycle rim 29 or also known as gear group.
In general, the group can currently be composed of versions 1, 2 and 3X, that is, from 1 to 3 crowns.
In each of them, the amount of teeth in the cassette varies to suit different types of cyclists and their focus . In general, 1X these days has been quite common among the most high-end bikes and even reaching 9-speed models.
Groups are responsible for helping to better transition between different types of terrain, and the famous 1×12 with cassettes of 50 or more teeth help to climb steeper slopes even more easily than groups of 2 speeds.
There are some points that for beginners may seem strange in a 1x ratio. The lack of a front derailleur helps in the functionality of use, as well as reducing the weight of a changer, cables and the gear itself.
But there is also the compensation of the amount of speeds and gears in the cassette, which help in the so-called amplitude, compensating for the lack of more crowns in this case.
That\’s why keeping an eye on the group is so important. There are different brands with different compositions and technologies and this can greatly increase the value of the rim 29 bicycle. In the composition of the frame (carbon/aluminum) there is already a big difference.
So at this point, evaluating the modality you\’re going to ride, intensity and type of terrain are fundamental so you don\’t waste money and that the bike\’s configuration is more compatible with your needs, especially on hills and flat terrain.
Check the suspension and components
Currently, bicycle prices are on the rise due to market demand.
What would be ideal is the visualization of the bicycle as a whole for a better choice, but this is not always possible, so analyzing the group is fundamental for the values and then verifying the other components.
Among them, the ones that are most important in this case are the tires, after all, they are high value bike parts , and if they are in disagreement with the place you are going to ride or the sport, they can affect safety and performance.
Finally, the suspension is also important due to the conditions of use , thus favoring the ability to absorb impacts in extreme use and which, contrary to popular belief, requires a series of precautions for greater durability.
These little tips can help you choose your 29 rim bike much better and of course with the right equipment and accessories you can face the sport you want with great quality.
