"In particular I look to use the iBike in time trials in order to improve pacing my effort, and so I do need something that gives me a good readout in realtime" we all want real time accuracy richard, but lets face it, we are not going to get it with ibike . the only time it gets accurate ...

i am going to try a new set up on the TT bike, i'm going to try a RWS type set up and see how i get on. i have moved the mount onto the stem, changed the stem to lower angle. the unit is very solid which is good as i'm having another try with the GEN 1 ibike for reasons which will become clear later.

oh i see, it was just coincidence that the power began reading normal when i got off the bumpy road? it seems odd as the power was ok warming up, it was only when i got up to full speed on the bumpy chipped road that things went haywire, it feels like cobbles to ride on. things were still going wron...

at times on the graph the power drops to 0 in the first 2 miles and stayed there quite a while, this must have an effect on the average watts and i presume on normalised watts too. in between those 'negative power' spikes i am quite constant at around 320, so i am wondering what i can do to erase th...

i went out to do another fitness test on the training bike with GEN3 pro clamped to my tri bars. i rode an out and back . what i didnt really take into account was the resurfaced road is very rough and may cause problems for the ibike. i started the test with a huge tailwind. i was pedalling as hard...

thanks for trying todj, but i put in my details and the watts seem a lot lower than i see in the ibike, that is using .0055 and .0033 in your chart. it gave 260 watts for riding at 30mph .0055, seems kind of low to me for such a high speed average but may be possible i suppose, but how fast would wi...

great thanks a lot, i will load that up. i felt the watts seemed a bit high on the display after the cal ride, not by a huge amount though. a lower Crr may drop the watts i expect, i suppose a fitness test is the real gauge of how good the profile is. if i dont race on sunday i'll try to do a fit te...

The only comment I'd make on the profile (hopefully helpful) is that a Crr of 0.0033 seems awfully low to me. You probably have much better road surfaces than we have in the UK, but even on my own TT bike which has Vittoria CX tubulars at 120psi I've struggled to get below 0.0055. With regards to t...

ok here is what i got. my settings are to auto analyze so you might want to revert to original at some point. Crr will need to be lowered closer to .0033 to be accurate for my tyres. hope i got the right files that you wanted, cheers

ok great, i'll try that. i actually did a fast start last night while sitting at my PC, but i suppose if i do set up again and select fast start no before my ride, the details will be ignored? i have also changed to profile 2 now, i will use that for TT bike and prof 1 for training

will try to repeat a cal ride and coast downs with the GEN3 and see what i get. looks like i'll just have to use the gen1 on my road bike so i can mount it on the stem. thanks for the help guys when i begin again with cal ride should i go back to the beginning with a fast start, then cal ride and CD...

First off, don't give up. Fernando was a HUGE help to me in understanding and dialing in the unit. Second, the mount that he showed pictures of is mine. I will tell you that regardless of how stiff/tight.whatever the extension seems to be, it probably isn't. The mount I made was using .075 stainles...

just checked the tilt plot, there is massive vibration as far as i can see and i do not understand how it can happen when all tubing is rock solid and clamped to the stem. is this a GEN 1 issue? i dont see how the unit could be more firmly in place

i managed a ride today with the ibike set up as in the picture, just lowered slightly, at first sight it seems another hopeless attempt to get a good profile. the protocol of todays ride. i use the GEN1 as i want the GEN3 on my training bike to avail of the inbuilt training sessions. i rode a couple...

the tubing is cut short and clamped to the stem, not running from the bars, it is very solid . i may cut it a little shorter to lower it slightly. To be honest i'm not too keen on the idea of importing a RWS as the price seems extortionate for what isn't much more than a piece of plastic tube. by th...

a piece of tubing clamped directly onto the stem,(which i have changed to a narrower one), this make a very solid base for the unit and i think less prone to vibration than having it on a horizontal arm. all connections very solid, should be no movement, and good view of the wind from all areas.

actually it looks better on the pictures than from my view, just fits in that empty space nicely. still worried that breathing may mess up the wind though and lowering it may help, or moving it forward, i have some other ideas if this wont work

i'm working on something at the moment which would set the ibike above my arms, i figured above or below makes no difference, it is going to be in the wind. the only problem i have now is that it is set too far back and i'm worried my breathing may actually affect wind reading, it would be just a fe...

Fernando, i have looked at mounting the Ibike on the stem, it is not possible, firstly the stem is oversized and the mount will not fit, secondly there are cables running over the stem that are in the way, 3rdly the stem angles upwards and the unit would not be close to level. in other words, forget...

ok thats interesting to know about the vibration, i presumed the bar would be quite solid in that respect, obviously not. i'm not really sure i have room on the stem to mount the unit as my arm pads are close, i will look into it again, i'm currently trying to set up the ibike on an aerobar extensio...

ye i can see how wind from the left will be affected, but for the time being there is no other place i can set up. i was considering fitting an extra tri bar extension which drops down at 45 degrees so the uniot would be between the top of the wheel and the bottom of my arms but i couldnt get the un...

ok, i'm doing a long ride tomorrow with some hills, so will be interesting to see what comes out of that, if everything works and the battery lasts 4 hours i am confident of being quite close to a decent profile on the training bike, but the TT bike is a different story

lol, im well known for my uniqueness

ride file of the 2 up, conditions very windy, headwind/side wind out. i dont know if any useful info can be gotten from this file, hopefully an expert can tweak something. analyze wind doesnt look right so it may be something to do with that which is throwing the numbers out. i did a calc wind befor...

here are 3 pics of my ibike set up on the bar end, best place i can find for clear view of the wind, and i think clear of turbulents from my hands. todays TT was a disaster, the profile is hopelessly wrong. firstly for some reason pulse failed and i had to ride on feel alone, so have no pulse data, ...

yes i always keep the same position on the bike for coast downs and do not move at all, i even try to begin coasting at around the same part of road. on the 6 or 7 CD's i did last, the last 2 i tried a different hand position to see if it affected results, the last was also in a different direction ...

thanks, helpful as always. one thing putting me off the upgrade is the big sting i got hit with for import tax when i got the Gen 3 unit. if i upgrade i will not only end up paying pretty much the same as for a new unit, but also run the risk of that tax again when it arrives here. the beauty of the...

ok, i managed to find 4 ibcd4m files saved from the date in question. i have included 3 of them, i presume each is a different cal ride which i have played around with in an attempt to get a good profile. any advice welcome.

i purchased a used GEN3 wireless pro a few weeks back, and with some help from the forum, i have just about got that profile set up right for my race bike. Now i had a chance to pick up a GEN 1 wireless pro at what i consider to be a fair price for a new unit, to use on my training bike, and maybe t...

thats great advice and clears up a lot of doubts i had, will post again if i can't get it figured out
