Jamis Bicycles: review of models, reviews, specifications

For all its simplicity as the basis for bicycle transportation facilities gives plenty of opportunities to implement various structural, functional and ergonomic solutions. Models of the latest generation is confirmed, regularly surprising even experienced riders with new technological developments. Company Jamis - bicycle manufacturer, which focuses on the ever-popular niche of professional mountain to the city's amateur modifications. A rich 30-year experience in this segment now enables designers of this brand to explore new directions, using their own unique solutions.

The main characteristics of the models

Product specification standardized bicycle and approached in different versions, but there are notable differences in the design of the device depending on the destination. Thus, urban model and version for cross-country weigh about 13-14 kg, are 21 to 27 and the velocity of the aluminum alloy frame. At the rim diameter is generally 26 inches, although there is a 29-inch versions. A classic example of such a version with a set of characteristics is a bicycle Jamis Trail, positioned as universal bike, but with an emphasis on the use of mountain ranges. In urban models less weight - 11-13 kg, but the choice of speeds their modest - a maximum of 3 and is generally 1-2. In this segment of road bike version stamps are presented weighing 11.8 kg, but with speed modes 16 to 20, which also extends the possibilities of their application.

Manufacturers Technologies

A key factor in comfortable and safe operation of the bicycle Jamis developers find the optimal location of wheel axles. To do this, first of all the designers aim to provide movement, very close to vertical. This makes it possible to minimize the impact of the suspension in the course of driving. In order to further stabilize the suspension mechanism on the rear shock damping system is also used Pro Pedal. With this solution, an optimal position of the axes of rotation. Attention is paid to the design and reliability, which is especially important for mountain bike Jamis like Laser or Trail. For imparting high strength engineers reduced the dimensional parameters of the rear triangle. As a result, increases the torsional and lateral stiffness. Professional look can be seen and understate the position of the link Bell Crank, what was done for the universalization of its application in the different structures, without making adjustments in the operating parameters.

Trail model is the X

One of the most popular models among novice riders. Bicycling is a base class mountain bikes, but that does not mean that he loses much competitors on quality and performance. The frame structure laid high strength by 26 inches, are not cheap components and balanced steering glass. Many fans of mountain biking also emphasize good location brake cables and shift mechanism - they are derived under the top tube front triangular designs that reduce the risk of damage and contamination of the wiring. Transmission bicycle Jamis Trail X is represented by the system Shimano Acera, that is probably the weakest point of this version. Completing Acera line close as possible to the widely used public sector, so they are hardly suitable for the high requirements of extreme driving. But this impression is smoothed by a decent performance rim mechanics and fork RST Gila.

Model Dakar XC

This option can be a good solution for the cross-country. The model is provided with a frame chetyrehsharnirnoy suspension and good workmanship of damper Rox Shox Bar. Moreover, it should immediately be noted that the damping effect of the design lends itself to adjustment. Suspension travel in this case is 90 mm. The main frame material is represented by aluminum, but a special high-grade. In addition, it is worth adding and enhancing inclusion in the database as "kerchiefs" in the bottom of the pipe. The main drawback of bicycle Jamis modification Dakar XC is the impressive weight of 14 kg. I played on weight gain and frame structure and fork Suntour XCM size 100 mm, which is added, the total weight of 2 kg. Therefore, in order to facilitate the construction of many hesitant to replace the component. But Bush implemented a successful combination Geax AKA and bushings Formula tires. But in the harsh conditions of the rim may show a small "eight". Minimum error and narrow rims tolerant, but this fact alone inspires riders uncertainty in the course of driving. Protectors Bike wheels Jamis this version ideal for dry ground. As the practice of exploiting even slow the sharp rise without slipping overcome by bike.

Durango Model

This is one of the oldest series of the manufacturer, designed for mountain trails. If the previous generation of users criticized for insufficiently strong design elements, the last modifications such flaws can be traced all the rarer. There is also a 26-inch model and the version of the representative added Durango 29 Sport wheels with a diameter of 29 inches. Hinge of the basic version is equipped with a fork RST Blaze and the already mentioned transmission Shimano Acera. The frame is also implemented on the aluminum alloy, which not only looks solid, but also causes a modest weight construction. As a result of simple geometry found a decent reel, springiness and ergonomics. It is noteworthy that in the bicycle Jamis Durango new generation of short feathers were used with the front triangle. This decision is surprising just because of the larger diameter wheels. However, such a device is allowed to make the model more maneuverable and comfortable to operate.

Model Renegade Expat

A solid bike's road version of the modern, providing leading edge technology, high-quality alloy frame and clear functional mechanisms. Suffice it to say that the basis of the bicycle laid carbon-fiber monocoque and the same carbon dropouts. Despite the appointment of a responsible and solid construction, the model turned out easy and comfortable to operate. An interesting feature of Renegade Expat is a bet on the classic mechanical brake Series TRP Spyre. This solution was used just to please the fans of slow, but comfortable ride for long distances. Jamis bikes differ in this series, and useful additions. The manufacturer has provided functional bumpers, as well as a removable retainer for the rear derailleur. Used in the construction of bicycle parts well-known companies, including Shimano.

Product Reviews User Jamis

The strengths of this bike company owners include sophisticated design, comfort and convenience in use. As for reliability, it is not all clear in this regard. Members noted that the frame, which are directly involved in the company's engineers, is performed at a high level and fully justifies the price list model. However, the versions of the lowest price category traced the presence of frankly weak mechanisms that are used to reduce the cost Jamis bicycles. Reviews indicate the use of forks and brake systems of budget categories. But this is just cheap models costing up to 15-20 thousand rubles. With the increasing price tag aligned and qualitative characteristics of the bicycles.

Finally,

Strategy Jamis manufacturer can be expressed as tending to reach the broad mass of potential users. In the line of all categories of demand and demand, reflecting the credibility of the brand from the different groups of riders. Of course, Jamis bikes are also in the face of fierce competition, as many eminent firms in each model will offer similar performance for analog. However, in the design qualities and design performance can be traced original handwriting experts of the brand. Also, during the operation the owners of bicycles there is increased ergonomics, even when it comes to brutal and powerful versions, designed for the harsh driving conditions.
