Rim brakes vs disc brakes - what’s the difference?
Traditional rim brakes apply the braking force on the outer edge of the wheel. A disc brake focuses forces on a smaller rotor, situated towards the centre of the wheel.
What are the advantages of a disc brake?
Power - Disc brakes generate an incredible amount of stopping power, usually far more than is necessary to adequately stop a road bicycle. This allows the rider to apply much less force to the lever before the bike comes to a halt. Less hand strength leads to a decrease in muscle fatigue, especially on longer descents.
Disc brake power can also be customised by exchanging the disc rotor (the metal braking surface) for rotors of differing diameters. A larger rotor equates to more powerful brake, useful for larger riders or heavier bikes.
Modulation (control) - Pulling with a specific amount of strength on the brake lever of a rim brake can result in wildly inconsistent results. When you pull on a disc brake equipped lever, resultant braking force is much more consistent. This reliability allows you to accurately judge how much force you need to apply in order to achieve the expected result. So despite it being easier to lock up a wheel with a disc brake, the feedback at the lever means you are far less likely to do so.
Disc brake advocates often state that disc brakes actually make you faster as technically you can spend less time ‘on the brakes’, allowing you to brake later before a corner and increasing the time spent at higher velocities.
Reliable, all weather braking - When you apply a rim brake in wet weather there can be a split second delay before you start decelerating. This delay is due to the brake pad displacing water and road grime from the rim to enable sufficient contact and friction. As such the actual braking force you apply in the dry might not stop you in the wet. If you have carbon rims, this is further exagerated . The location of the disc rotor, plus the generally protected calliper position normally results in very little impact to a disc’s wet weather performance.
Bike Shorts Were Officially Paris Fashion Week’s Most Curious Trend
The Tour de France might seem an unlikely place to spot trends, but the competitors’ skintight shorts are the latest summer must-have among the style set. Don’t worry if you don’t own a bike ....
At Paris Fashion Week, the show began and ended with bike shorts. Off-White closed with Naomi Campbell in ivory bike shorts and a blazer. These are not isolated incidents as spandex bike shorts appeared at both Dolce & Gabbana in Milan and Dion Lee in New York
Apparently the most-wanted is a £300 pair of black neoprene shorts by Kanye West’s label Yeezy, which sold out after being worn by Kim Kardashian and Bella Hadid. The style, a collaboration with the Australian sports performance brand 2XU, is made from a compression fabric designed to increase blood circulation to the muscles. Though they look similar to the pair Geraint Thomas has been wearing in the Alps, Hadid styled hers with a crop top and a diamond necklace for a night…
