Hey JulianBoulter, Another cause of higher CdA is yaw angle. If you have ideal no wind conditions and do the coast downs, this snapshot will still read higher if you have a headwind from off axis due to the larger 'picture' or area that is actually facing the wind vector directly. This is because yo...

I used some of the techniques that I mentioned in above post today after my ride. Because I had the issue in mind, I soft peddled in several places during my ride and tinkered with my CdA and Crr values after the fact. N_Loop_140301_z31.jpg It turned out that this steep downhill followed by uphill (...

Hi JulianBoulter, I will try to tackle your first question: "is there a way to work backwards then so that I can take the Cda figure I saw in the snapshot Cda of 0.45 and calculate what the Crr should be to give that Cda? " My analysis of your question brings up a subtle point that you may...

Called GMR Descent on Youtube, Nice display of iBike data on left in video. Really cool combination of products for iBike data enhanced video! He used a Pro now someone do it with a Newton+ ! Enjoy, Russ GMR Descent Ernest Villalon Uploaded on Aug 30, 2011 "Glendora Mountain Road (GMR) descent ...

Hi JulianBoulter (and Kens!), I would only add to what Ken said if you did coastdowns vs the iBike height and weight setup approach. If you did coastdowns, then iBike attempts to measure both Cda and Crr with complex math that looks for the Cda part at higher speed and the Crr part at the lower spee...

Hey Drissmalet,

I am sure they will ask for the file so go ahead and upload it to save time!

JulianBoulter, You said: Regarding your bullet 1, I didn't see any other way of doing this as I had not entered the user setup routine prior to the calibration ride, so you are saying that when using the unit for the first time you must either enter the user setup routine prior to the calibration ri...

lavoww, You might want to try a 'hard reset', see page 62 of this pdf file on how to do a hard reset: http://www.ibikesports.com/Download/iBike_Instructions_June_09_red.pdf Also I would try using a small plastic tube such as comes on some spray cans such as wd-40 etc (a clean new one is preferable) ...

JulianBoulter, You may want to also get the RWS (remote wind sensor) for when you have the bars attached. In that case, I would suggest using two profiles and having done the cal ride for each you would be good to go. The RWS samples the air from in front of your aero bars so that it is not affected...

Congratulations Velocomp! Very nice review. I notice this may be able to use a translation touch up under software: "Also iBike has developed with Isaac a very graphic software with many features, but they reveal themselves right away only to absolute professionals." I suspect it means, to...

Texmurphy, I agree with Velocomp but in the interest of trying to save spending money, I would first try moving the sensor further or close and possibly the magnet further from the hub if it is not fairly far away, for instance. You may find a sweet spot that works better, or not. If you can tolerat...

Happy New Year iBiker's ! I have thoughts of an improvement in Isaac. The problem I find is when I want to highlight a large section of the ride with an exact start and finish. Unless there is a way I am not aware of, it is a very tough task. What I am thinking of is, somewhat like the addition of l...

w01fy, I have had an Aero iBike for years, the Newton+ now but no DPFM :-( However, there are lot's of posts buried in this forum about that but my quick search did not pull up a gold mine. I did continuous cDa and DPFM cDa in the search box upper right, you may want to do that and expand from there...

Be sure to read the comments after this generally quite good but somewhat also critical review. Most of the critical comments are fair but are nicely balanced to the better by user comments.

I had not noticed this posted to the forum.

RGV Cycling had an initial review earlier but
this one is with more experience under his belt.

Enjoy!

doctorb,

No, not in Isaac but you can read an exported CSV file into programs like Golden Cheetah (free) and do the quadrant analysis among many other nice features. Check it out!

blueraidermike, The most accurate way is to do cal ride with coastdowns with that equipment to develop a matching profile. A couple of short cut ways to get (how?) close would be: 1. Assuming you are using same tires and pressures for should be same Crr, do a few runs down a hill and analyze the Cda...

JoseJ,
The cal wind is in the setup menu. It is normally only necessary just prior to your cal ride, with the Newton series. If the temperature changes a lot, maybe another cal wind.

Search the forum for cal wind, lots of old discussions about it.

Russ

Hi JoseJ,

Since you say your mount has been loose since originally mounting it, probably best to do another cal ride.

Texmurphy, I could not resist the poke at PS bs :-) However, for sure, if you can peddle to keep the water bottle from sloshing, you have mastered smooth peddling and riding! I was actually thinking more about the slosh of a partially filled water bottle causing a random contribution to the force ve...

PS bs has a nice ring to it!

My son has a Galaxy S 4, someday he will upgrade
Thanks for the idea, will give it more thought!
Russ

Thanks John and racefern, I think I have the picture now :-) Anyhow I am one who reads the announcements and then my imagination tries to insert functions that could be but were not stated. As far as smart phones go, just resisting another data plan cost. If I go for the smart phone and it's plan, I...

John said :

4) There's no difference in ride stats if you use a Garmin or the Newton+NT.

My question (I have a Garmin etrix) is what extra function/feature/information do I get without the app but with the Garmin, if I purchase the key? Sell me on this and I will spend the money : -)

Thanks,
Russ

racefern, I may not use the graph much in the future, not sure yet. Guess I am sometimes pedantic. However, I had the TSS data siting in a column in monthly spreadsheets for the year anyway so it was easy to start from Jan 01 to current. I have a blood pressure tracking spreadsheet from the web by a...

Racefern and Zoltan, Thanks for the replies! However racefern said: I've been using manual merge for years and it works very well. It is "labor intensive" and that's why I like the Newton Tracker option. Just like all the other add-ons for a Newton, the Tracker is not an absolute necessity...

racefern, That is a nice spreadsheet, thanks for the post. For help to other excel novices, like me... it took me a while to figure out how to put the date into A3. Duh, select the A3 cell and change the date up in the function line. Then I noticed that it was helpful, for the graph, to either enter...

Hello Velocomp, This looks great, but I have no smart phone. I do have a Garmin etrix gps. I have been able to merge the etrix gps file with my iBike file in Isaac just fine. It is especially cool that you also include the Android app but only my wife and son have those, not me :-) While I am not a ...

On the RWS even on Gen III. ... I used a wide (about 1/4 inch) variety rubber band and give it one half twist after looping if over the neck of the wind sensor just above the plug. Then I pull the rubber band over the iBike and adjust its position to best help hold the RWS in place. Even now on the ...

Well racefern,

I though of that too late
Great idea. Another great thing is Isaac fixed all the problems in what was recorded !

Thanks,
Russ
