Le « Guidonstop » SIMPLEX

[Ebykr summary; the article’s text is not reproduced. The notice says the Établissements Simplex, whose reputation in the field of the derailleur is long established, have just brought out a new product worth attention, the Guidonstop (the opening sentence is broken by the drawing). It describes the Guidonstop as a high-safety braking system for cycle and cyclomotor, represented by the two figures illustrating the article, and gives its characteristics as the list below.]

— Montage instantané à la place de la potence classique et
serrage normal par expandeur.
— Permet l’emploi de tous les cintres de guidons (excepté les
guidons « course »).

[An editorial note set in the magazine’s own column: a heading in roman type, right-aligned, with the firm’s name in capitals, over an italic opening sentence that is split in two by a ruled square panel. The panel holds one line-engraved drawing, shaded with fine hatching, of a handlebar stem clamp seen from above and the side: a cylindrical clamp with a round bore and two bolts at the top, a short stem running down into the fork column with a ribbed locknut, and a small bracket at the left from which a braided brake cable hangs down, with thin cable lines crossing the clamp from the upper left. The artist’s boxed monogram “DR” (Daniel Rebour) is drawn at the lower right of the drawing inside the panel. Below the panel the italic text continues with a dash list that is cut off at the foot of the crop. A three-star break mark, belonging to the preceding notice, sits at the top edge. No agency mark appears.]

— Peut actionner tous les types de freins (tenailles, cantilever,
étriers, tambours, etc…, etc…).

[Ebykr summary; the article’s text is not reproduced. The notice says this control device permits the list below, then adds that to these advantages should be added easier handling of the cyclomotor, through the possibility of reducing the throttle (gas) and braking at the same time.]

de freiner instantanément, sans chercher les leviers de freins,
par une légère rotation du guidon (pas de crispation des doigts) ;
de tenir normalement et confortablement les poignées du guidon
en effectuant le freinage, et conservant ainsi le contrôle absolu
de sa direction ;
une position très confortable des mains.

[A text-only continuation of the editorial note in the magazine’s own column, set in italic roman type: a dash list item, a short run of italic lines, and a closing paragraph, with no drawing, photograph, signature or agency mark in this part.]
