Hi,

what do you think about a data field showing the current gear (calculated from the gear ratios stored for the current bike profile, the cadence and the current speed) ?

With best regards,
  TJ

  Great idea... for me would the gear inches be enough:

  ...but might be too old fashioned for some ;-)

  IpBike has something like that.

  Hi everyone,

  This is really a good suggestion and idea we love. For that reason, I am forwarding this to the development team. They will be happy to discuss this.

  The values to calculate the gear inches is already present if there is cadence available:

  spd= speed in meter per second

  cad= cadence revolutions per minute

  60= to get speed per minute

  25.4^-3= go from meters to inches

  gear inches= (spd x 60) / (cad x pi x 25.4^-3)

  I hope this makes sense, but again, this is an old fashioned way to show gear, I am not sure how popular this figure is these days, but for me would it be great, and “simple” to implement ;-)

  For e-shifting there are already the data fields. They also could easily be used for non-e-shifting gears. I really like the plot (see below):

  I use Di2,

  I think is useful also real gear indication i.e. 53-15 or 39-23 some exercises are done by gear, cadence and power
