Thanks for the help, I did not know about the cadence factor and I will start measuring this.
[QUOTE=SweetLou;5947160]The cassette has 8 cogs, with the smallest cog having 11 teeth and the largest cog having 30 teeth.
So what is the difference with for example a 12-25, 10 speed in terms of performance? what´s the meaning of the cogs having more or less teeth and the cassete more or less speeds.
Best regards
