I'm a self-teaching geek. teaching because that process is far from over. I don't know a ton, but what I know, I'll share, and I won't answer a question if I'm not confident I'm correct.

@Rider_X As are many of the "When and Why should I change my chain?" questions already on the site.

@Rider_X Only for manufacturing purposes. For fitting purposes, not useful except in the context of a specific rider.

comment Pressure mapping a Brooks saddle
It doesn't. Regardless of the brand you are asking about, pressure data like this is only good for one thing. The thing that makes this not useful to others is that you are asking for a data source for research. Anyone not doing your research, doesn't need that. I appreciate that you want to learn, and tried to point you in the direction of someone that might have the answer you want, because I'd like to be helpful. But the question and its only possible answer are not on topic here, in my opinion. Any further discussion should be taken to meta.

comment Can shimano di2 be programmed to be automatically readjust shifting for different hub/wheel types?
Not for Shimano, no. With SRAM's upcoming electronic group, there is a wireless system in the prototype phases, but it's not close to release. Shimano doesn't see the utility, since on a wireless system, each component has it's own battery, and needs to be charged separately. In addition, if your friend said the only wire was going to the battery, that would indicate a single battery system, and that isn't possible with a wireless system. Each radio receiver needs a power source. If there is no wire, it needs its own battery.

comment Pressure mapping a Brooks saddle
If it was useful for me to have someone else's saddle scan in relation to my fit, then I could see the utility for general use. Since it isn't useful for fitting, unless I have my own scan done, then at best this is requesting "product, service, or learning material recommendations", and off topic. That said, if you all think it useful, feel free to vote to re-open.

comment Pressure mapping a Brooks saddle
@NeilFein The question asked is does anyone have a database of pressure data regarding a particular brand of saddle. GebioMized pressure data is specific to the type of saddle, and the rider sitting on it. It is good for 2 things: Making modifications to saddle choice or position for a particular rider, or designing a new saddle, using a wide range of pressure readings on a particular saddle to design a new saddle or chamois. Unless someone intends to do one of those things, the data is useless.

For what it's worth, the GebioMized system is awesome. Michael Fuhrmeister at GebioMized has been very helpful with everything we have needed related to the pressure mapping software and the scanner. I think he would be happy to help with this, assuming the data isn't proprietary.

@jimirings That was my interpretation as well. I have nothing against the OP, and attempted to answer his question, but I don't think it will be useful to anyone else in future, which is my key metric as to its utility.

comment Pressure mapping a Brooks saddle
@Rider_X The OP did not ask a question about saddles or bike fit. He asked a question about a source of information for a research project. I did my best to supply that info, but I don't think that the question itself is relevant here.

comment Pressure mapping a Brooks saddle
@NeilFein The question is asking for a database of pressure mapping info on one particular brand of saddle. I agree that the end result of the research he proposes would be useful. I do not agree that the source for the database is useful to anyone not conducting that research.

Manuals for Shimano Di2, both road and mountain, are available at si.shimano.com.

The communication protocol it uses is ANT+, not bluetooth. Since there is a wire connecting the derailleur and shifter, there is no need for wireless communication there.

@PeteH Dura Ace 9070, the latest Shimano Di2, doesn't and can't communicate wirelessly between shifter and derailleur. There is an accessory called D-Fly which allows limited wireless data transmission to a connected cycling computer which has been designed to accept it. It also allows buttons on the shifter to control the screen on the cyclometer.

comment Pressure mapping a Brooks saddle
I'm voting to close this question as off-topic because the required knowledge to answer it is very specific, and not likely available to anyone outside of the Brooks or GebioMized companies. I would suggest directing questions about the data availability to Michael Fuhrmeister at GebioMized. The company was started as a research division of the Sports University at Freiburg in Germany, so I'm sure they would be interested in furthering the research in this matter. It also has no long term benefit as an answer for future users of this site, in my opinion.

While GebioMized is an excellent system for this purpose, I'm not sure this question is a good fit for the Bicycles.SE site. It requires specialized knowledge, and if answered will not benefit anyone on the site other than the OP. That said, I do think the research itself would be useful.
