Who would have thought that the largest bicycle manufacturer in the United States, TREK, actually originated in a rural barn, after more than 40 years of development, TREK has become the world's leading bicycle company, with the world's largest dealer network, Trek can produce the top race cars, but also developed a lot of models suitable for the public to buy, each model affects the technical trend of bicycles.
 
TREK's mastery is OCLV (short for Moderate Compression, Low Voiding) carbon fiber technology, and the resulting OCLV Mountain is carbon fiber specifically designed for mountain bikes. As we all know, carbon fiber has high tensile strength, but low shear strength, and in the event of a collision, the strength is not even comparable to that of aluminum alloy. In the rocky suburbs, bumps and crashes are unavoidable, and poor drop resistance can be said to be the pain point of carbon fiber frames. OCLV Mountain is stacked with different composite materials to make the frame more elastic and maintain a good load capacity after impact, and it is also equipped with "carbon armor" on the surface of the impact-prone parts, which is an elastic protective layer that multiplies the impact resistance.
 
The TREK naming convention is the model number, and the higher the number, the higher the configuration. The hardtail model is rich in style, and the entry-level Marlin series starting at 2000 yuan allows entry-level riders to ride the Trek car, but its configuration is lackluster and is not competitive at this price point; The X-CALIBER in the price range of more than 5,000 yuan has upgraded the aluminum alloy material process, and the addition of hydroforming and pipe extraction technology has reduced the weight and increased the strength, and the frame uses a more professional competition-level geometry, which has begun to have a certain degree of professionalism; Superfly is TREK's highest-end hard-tail aluminum alloy model, and the multi-stage cold-pressed aluminum alloy has a higher level of strength, but its high price of 10,000 yuan can already buy good carbon fiber models from other brands.
 
The Procaliber is TREK's top-of-the-line hardtail model, powered by OCLV Mountain carbon fiber, the first to feature IsoSpeed disconnect technology for its flagship road bike, which roughly works by separating the chainstay from the seat tube to create 11mm of travel, similar to a softtail, allowing vibrations to be dissipated throughout the frame, taking hardtail mountain bike comfort to a new level without compromising the rigidity of the frame and without adding extra weight.
 
One of the features of the TREK softtail is the use of the ABP suspension system, which is a modified single-turn point structure, and the biggest advantage of this suspension technology is that it can largely avoid the interference of the brakes on the shock absorbers. The rear suspension of general models will have a certain rotation angle relative to the rear axle when the rear triangle is in action, and the rear axle and the rear triangle are tied and locked by the brake system when braking, and can no longer rotate relatively, resulting in the obstruction of the operation of the shock absorber, which is called brake interference. The rear triangle of the ABP suspension system is not a welded fixed triangle, and the two brackets that connect the rear axle can rotate freely regardless of whether the brakes are braked or not, thus avoiding brake interference.
 
The single-turn point structure cannot avoid the situation of stepping on the deflating force, and the pedaling rigidity is not as good as the virtual turning point structure, but the suspension structure can not be handed over to the shock absorber to solve. TREK has partnered with Penske and FOX, leaders in racing suspension design, to develop the "RE:aktiv" suspension liner technology, which compensates for the shortcomings of TREK's softtail suspension system by combining pedaling rigidity with suspension agility.
 
TREK softtail models are divided into different models according to different races, and the top manufacturers basically use this classification. From low to high itinerary, "Top Fuel", "Fuel EX", "Full Stache", "Remedy", and "Slash" are listed. The suspension mechanism of the different Trek softtails is basically the same, but the stiffness of the frame, the size of the wheel diameter, and the geometry will be adjusted according to the needs of the race. Soft-tail models all belong to the high-end series, a single liner costs several thousand yuan, the price of the aluminum alloy basic model is about 20,000 yuan, the carbon fiber version is basically more than 30,000 yuan, and the model mantissa is 9.9 for the flagship of the flagship, the price is about 70,000 to 90,000 yuan, which is not a plaything for ordinary enthusiasts.
 
TREK's quality control is excellent, even the frame of the entry-level model has a limited lifetime warranty, and whether it is purchased online or in a physical store, it is much more convenient than those high-cold European and American brands that do not even have a Chinese official website. Larger cities basically have TREK specialty stores, so you might as well check them out before you buy.
