Here are the crowns with Ø94mm hub hole from CHARVIN Industrie for Peugeot 103 with 5-spoke jail rims. With a wide choice ranging from 43 to 56 teeth, you will be able to fine-tune your transmission settings. A large crown will allow you to get more acceleration (also take into account the variation / clutch part) while a smaller crown will offer you an extension in speed at the expense of acceleration / recovery!
It's up to you to find the right compromise according to your configuration. It is strongly recommended to change its chain and its sprocket to start again on a new transmission without problems. A crown of excellent quality Made in France with an alloy of treated and machined steel. An element intended to last over time, do not forget to grease your chain well to avoid friction between the sprocket / chain / crown (to reduce heat, wear, play, etc.). Model 10 fixing holes in width 415.
Be careful to select the number of teeth before adding to the basket.
