Le nouveau dérailleur CYCLO

[Ebykr summary; the article’s text is not reproduced. The Cyclo marque brought a remarkable novelty with its floating-jockey-wheel derailleur (dérailleur à galet flottant). The system keeps the jockey wheel (galet) always in the axis of the chain link, which avoids the « cognement » (knocking) of the wheel against the side plates (flasques) of the chain. The author says the derailleur works both smoothly and firmly, surely and without jerks.]

[A short text-only notice with no drawing or photograph. The heading “Le nouveau dérailleur CYCLO” stands at the upper right in a bold sans-serif face with the name in capitals. The body is set in a slanted italic roman face with the name Cyclo in upright roman in the first line. No signature, address or stand number appears.]
