The V-scale doesn't consider risk and is purely focused on the technical difficulty of the movements. [2] The V-scale is the dominant scale in North America, and it and the Font scale are the most dominant systems worldwide; beyond the easiest grades, the two systems can be almost exactly aligned in comparison tables.

The notable first ascents that set a new highest-grade prior to The Face were traditional climbing routes: . 8a (5.13b) [m]. Grand Illusion – Sugar Loaf, Lake Tahoe, CA – 1979 – First-ever consensus 8a (5.13b) in history, by Tony Yaniro.
The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
Climber leading the sport climbing route Hulkosaure 8b (5.13d). Quickdraws have already been attached to the line of pre-drilled bolts that mark the route.. Sport climbing is a form of free climbing (i.e. no artificial or mechanical device can be used to aid progression, unlike with aid climbing), performed in pairs, where the lead climber clips into pre-drilled permanently fixed bolts for ...
Ueli Steck making a rapid 'alpine style' one-day ascent of North Couloir Direct (VI, Al 6+, M8) a major alpine climbing route on Les Drus [6]. The derived term "alpine style" alludes to the fashion of alpine climbing to be in small fast-moving teams – or even solo – who carry all of their own equipment (e.g. no porters), and do all of the climbing (e.g. no sherpas or reserve teams laying ...

Climber leading a traditional climbing route, attempting to insert a nut for climbing protection.. Traditional climbing (or "Trad" climbing), is a form of free climbing (i.e. no artificial or mechanical device can be used to aid progression, unlike with aid climbing), which is performed in pairs where the lead climber places climbing protection into the climbing route while ascending.
