Unfolding: derailleur vs Pinion<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Comparison of the drives<\/h3>\n\n\n\n

The stromerforum.ch<\/em> - Moderator @bluecat<\/em> has a graphical comparison of the drives here<\/a> published.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The diagram shows the gear ratios. The derailleur gear system is based on an 11-42T cassette, a 52T chainring and 27\u00bd\" (26\u2033) tires.<\/p>\n\n\n\n

Legend:
x12; x9; x6 = Pinion gearbox
S\/A = Sturmey Archer
52-11 = Chain with 26\u2033 tires
x-axis = gear
y-axis = unfolding (meters covered with one pedal rotation)<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

In this graph, the derailleur is compared with a cadence of 75 and the Pinion with a cadence of 60, so that the difference in gear development does not count.<\/p>\n\n\n\n

Legend:
x-axis = gear
y-axis = gear step in km\/h<\/p>\n\n\n\n

Gearbox design calculator from Pinion<\/h3>\n\n\n\n

The Pinion gearbox calculator<\/a> or a Pinion calculator<\/a> helps you to select the ideal transmission setup. The internal ratio for each gear of all gearbox types is already defined. The entire range of a Pinion gearbox can be shifted to fast or slow with the secondary ratio to the rear wheel. By using sprockets or toothed belt pulleys of the same size, 1:1 tuning is also possible.<\/p>\n\n\n\n

Cadence comparison chain \/ Pinion<\/h3>\n\n\n\n

If you want to know what the cadence is at vMax=45 km\/h, here is a comparison of an ST3 with Derailleur gears<\/a> and a Pinion C1.9.<\/a><\/p>\n\n\n\n

Here you can see that the Pinion (Tf=62) requires around 10 revolutions\/min less than the chain model (Tf=72).<\/p>","protected":false},"excerpt":{"rendered":"
