  Since the introduction of the first disc brake road bike, fierce debate has been around and this year's Tour de France is no exception. Here we will give a detailed and comprehensive introduction to the advantages of disc brake roads in terms of braking ability, adjustment, etc., as well as the rim brake system that has sufficient advantages in terms of lightweight, easy to use, and adjustable at any time. Nevertheless, we also foresee that the two sides will not completely agree with the other's views. Given that the Tour de France, the biggest event of the season, has just ended, we might as well take a look at whether the "Death Razor" disc brake road or the "Rain Brake Road" rim brake road won more stages. The vast majority of brands that sponsor World Tour teams are or have eliminated rim brake roads. However, there are still some riders who are holding on to the rim brake road, and even some frames have been discontinued but are still favored by prof...

  According to the model, the wheels of road bikes are mainly divided into three categories: road bikes, time trial/triathlon and all-terrain road bike/CX road bike. Let's talk about the difference between the three types of wheels. Excluding the shape and structure of the wheel set, the width of the rim is also different due to the different tire widths used in the three models. Nowadays, road vehicles generally use 25-28c tires, so general wheel manufacturers will optimize the wheels for these two specifications. Due to weight control, aluminum alloy wheels are generally not too wide. Nowadays, the mainstream inner width is 17mm and the outer width is about 22mm; the disc brake aluminum alloy wheels will be slightly wider by about 2mm because there is no brake edge. Because carbon fiber wheels are lighter, manufacturers can use some radical designs, such as widening the rim to improve stability in crosswinds. Starting from HED, manufacturers have begun to widen their rims. Among ...

  The 2020 Tour de France has ended for many days. There are surprises and surprises in this year's race. Today we will review these 21 stages and set the top ten events of the Tour de France.   1. Violent rain riding, multiple crashes in the first stage, a neutral game In the first stage of the Tour de France, the main group was caught off guard by a heavy rain. Many drivers crashed in the rain. Among them, there were many big-name drivers such as PILOT, LóPEZ, NIZZOLO and EWAN. The race was once into a neutral state organized spontaneously by the drivers. Rain riding is not terrible, the terrible thing is the slippery ground after rain. In the first stage, there are climbing and winding downhills. Once the car crashes, it will have a big impact on the next 20 days of competition. Therefore, in order to protect the safety of the main general, the teams finally chose a safe forward strategy. Despite this, the main group fell again at the 3km arch. For PILOT, the crash in the f...

  On September 10th, the twelfth stage of the Tour de France ended. HIRSCHI (Team Sunweb) made a solo breakthrough again. This time he finally realized his dream and won his first Tour de France championship. Coming to the 218km long twelfth stage, the first half is still a sprinter, and the second half is a little difficult. The second level climb with bonus time is 3.8km long and has an average slope of 7.7%, which is very suitable for short-hill explosive riders. The climb 5km before the finish line exceeds 100m, and a wonderful climbing sprint will be staged here. The race officially began, and many drivers launched a breakout action. In the end, only ERVITI (Movistar Team), SáNCHEZ (Astana Pro Team), POLITT (Israel Start-Up Nation) and WALSCHEID (NTT) successfully escaped from the main group, and inside the main group In a car crash, Guillaume MARTIN (Cofidis Solutions Crédits), LUTSENKO (Astana Pro Team), BONIFAZIO (TOTAL DIRECT ENERGIE), ROJAS (Movistar Team) and others fell...

  On September 9, the eleventh stage of the Tour de France ended. EWAN, SAGAN, VAN AERT and Sam BENNETT staged a wonderful sprint before the finish line. In the end, EWAN won the stage champion and once again stood on the top of the stage podium. Due to the intense sprint action, SAGAN collided with VAN AERT, the stage results were cancelled, and the sprint points were not collected. The eleventh stage is the last flat stage of the second stage of the Tour de France. The sprint points at the end are crucial for the sprinters to compete for the green shirt. The main group was downsizing again, and the FORMOLO (UAE TEAM EMIRATES) that crashed yesterday did not stand on the starting line today. In the neutral riding stage, LUTSENKO (Astana Pro Team) and ZAKARIN (CCC) crashed, adding a little episode to this otherwise plain stage. After the game officially started, LADAGNOUS (FDJ) broke through alone. Because it was against the wind, no one in the main group wanted to chase or particip...
