Abstract:
A light alloy bicycle rim comprising a base portion, two lateral flanks forming an outer braking surface, and a longitudinal hole provided along said lateral flanks and extending over a first portion of the height of the braking surface; said first portion of the height of the braking surface comprises a wall having a thickness corresponding to a shortest distance between the longitudinal hole and the braking surface; said wall is designed to be worn off down to the longitudinal hole so as to form a visible slit, while a second portion of the height of the braking surface, situated radially outwards with respect to the first portion, has a thickness such as to prevent deformations of the second portion when the first portion is worn off down to the longitudinal hole; said lateral flanks being further reinforced to prevent them from bending outwards when the braking surface is worn off down to the longitudinal hole.
