Claymore

A claymore (/ˈkleɪmɔər/; from Scottish Gaelic claidheamh-mòr, "great sword") is the Scottish variant of the late medieval two-handed sword. It is characterised as having a cross hilt of forward-sloping quillons with quatrefoil terminations. It was in use from the 15th to 17th centuries.

From the 18th century onwards the word claymore began to be used in Scotland and parts of England to refer to basket-hilted swords. This description was probably not used during the 17th century, when basket hilted swords were the primary military swords across Europe, but these broad-bladed swords remained in service with Scottish regiments for some time longer. After the Acts of Union in 1707 when Scottish and English regiments were integrated together, the swords were seen as a mark of distinction by Scottish officers over the more slender sabres used by their English contemporaries: a symbol of physical strength and prowess, and a link to the historic Highland way of life. Although these swords were no longer recognizable as the historical claymore, they were the broadsword of the era and so were referred to using the term. Such swords remained in service with Scottish regiments into the 19th century.

Mountain bike

A mountain bike or mountain bicycle (abbreviated MTB; or ATB, for all-terrain bicycle) is a bicycle created for off-road cycling.

Mountain bikes are typically ridden on mountain trails, fire roads, logging roads, single tracks and other unpaved environments. These types of terrain commonly include rocks, washouts, ruts, loose sand, loose gravel, roots, and steep grades (both inclines and declines). Mountain bikes are built to handle this terrain and the obstacles that are found in it like logs, vertical drop offs, and smaller boulders.

Mountain bike construction differs from a typical bicycle in many ways. The most noticeable differences are the inclusion of suspension on the frame and fork, larger knobby tires, more durable heavy duty wheels, more powerful brakes, and lower gear ratios needed for steep grades with poor traction.

Since the development of the sport in the 1970s many new subtypes of mountain biking have developed, such as cross-country (XC) biking, all-day endurance biking, Freeride-biking, downhill mountain biking, and a variety of track and slalom competitions. Each of these place different demands on the bike requiring different designs for optimal performance. MTB development has included an increase in suspension, typically up to 8" or 203mm, and gearing, up to 30 speeds, to facilitate both climbing and rapid descents. However, advancements in sprocket design has recently led to the "1x (pronounced one by)" trend, simplifying the gearing to one Chainring/Sprocket in the front and multiple sprockets on the rear of the drive train, more commonly, 9, 10 or 11 speed.

Red Bull

Red Bull is an energy drink sold by Austrian company Red Bull GmbH, created in 1987. In terms of market share, Red Bull is the highest-selling energy drink in the world, with 5.387 billion cans sold in 2013.

Austrian entrepreneur Dietrich Mateschitz was inspired by an existing energy drink named Krating Daeng, which was first invented and sold in Thailand. He took this idea, modified the ingredients to suit the tastes of Westerners, and, in partnership with Chaleo Yoovidhya, founded Red Bull GmbH in 1987 in Chakkapong, Thailand. In Thai, daeng means red, and krating is the large bovine called "gaur". Red Bull is sold in a tall and slim blue-silver can, while Krating Daeng is in a gold shorter can. The two are different products, produced separately.

The Red Bull company slogan is "Red Bull gives you wings", and the product is marketed through advertising, events (Red Bull Cliff Diving World Series, Red Bull Air Race, Red Bull Crashed Ice), sports team ownerships (RB Leipzig, FC Red Bull Salzburg, Red Bull Brasil, New York Red Bulls, Red Bull Racing, Scuderia Toro Rosso), celebrity endorsements, and music, through its record label Red Bull Records.
