Minimum Flüela grades, explained

MINIMUM Flüela

Minimum runs two bouldering halls in Zurich, Flüela and Leutschenbach. The Flüela hall on Flüelastrasse opened in autumn 2013 in a brick building with about 800 m² of bouldering, plus a second room of about 200 m² for warming up and training with a system wall and campus board. Walls are reset every week.

Bouldering grades

Boulders are sorted into colour categories, from yellow (easiest) through green, orange, blue, red and white to black. Minimum publishes a Fontainebleau range for each colour on its course-colours and route-setting pages, and the ranges below are copied from there. The site writes them in lower case, e.g. 6a+.

From the gym's own grading guide. Gyms reset and regrade often, and grades vary between setters, so treat this as a guide and check the boards when you visit.
