Duh! So as the op can have some measure of the distance they have done and then join in with all the fun on the S/C/R challenge 2011 obviously!!!
Distance is meaningless on a trainer. Totally meaningless. if S/C/R challenge is the goal then go for it, if the goal is racing well then dont.0 -

Tyre slip.
Tyre pressure.
Trainer press on force.
Temperature effect on body.
Resistance setting.
Gear selection.
If magnetic trainer - what about changes in magnetic resistance, not strictly consistent.
If fluid trainer - what about the effect of the temperature of the oil on resistance.
So many variables to be controlled to have a repeatible test.
Yes there are so many variables and you cannot perfectly simulate conditions in the real world. For example if you do a 3k run test on the track in December and again at the end of Jan you would note any changes in the environment against the benchmarked values of both tests. Track grip, runners, temp, wind etc...
I agree largely that distance is a less important value on the turbo but it has its uses. For the testing, its indoors so you can simulate a simlar enough environment and checking the trainer flywheel and tyre pressure for consistent variables will still give you decent test conditions. If you want measurement to the 0.001 percentile, it won't do obviously.
Lets say you are scheduled to do a 70km bike ride and its milling outside or iced over, or perhaps you have a target of 800km for the month. Distance is handy then too eh:) 0 -

How many people check the variable factors before use though.shotgunmcos wrote: »Lets say you are scheduled to do a 70km bike ride and its milling outside or iced over, or perhaps you have a target of 800km for the month. Distance is handy then too eh:)
In that hypothetical situation a trainer that has a load generator, hooks up to a PC, and simulates real world environments, terrain, wind and similar would be invaluable. Hypothetically speaking as well the 800km goal is probably out the window given health issues.0 -

LOL. sure I couldn't let you away with a statement like 'totally meaningless'
OT I changed my doc a couple of years ago beacuse the old family doc, ie my parents one, was a) oblivious to my sporting interest and b) my son didn't like him at all.
I found a doc who I like, had a keen interest in me and my families needs and simply gave him my old docs number so he could get the files.0 -

Crono fluid is quite, have the old version of it.mitresize5 wrote: »I've the Crono fluid as well - cant fault it for the money.I have the Sirius myself, ....I find it good, not too noisy - i can watch TV with it on, although my wife still let wont let me use it if she is trying to sleep
Thanks Folks, looks like they are both decent. It's good to hear from people who have used them that they are what they claim to be. Now, all I have to do is master my inner sloth.
Thank again0 -

It's not even properly winter yet and I think I've caved already and am going to get a turbo.:( Is it worth the extra few quid for the TACX flow for the power readings and hr etc?
You mean the Tacx Flow T1680?
I think I'll be going with that too.
I don't like training indoors including swimming :rolleyes: so I might even set up the turbo outside

I was setting up my new Turbo last night and have a few basic questions that someone might be able to help me out on. Its the first time I've even seen one so pardon my ignorance
1) Does the new quick release skewer that gets fitted onto the back wheel to suit the Turbo usually remain there when the bike is dismounted or does one change it back to the original skewer when going back out on the road?
2) Does the adjustable bolt / knob that controls the position of the brake unit and its resultant pressure on the tyre remain in the same position each time the bike is mounted or does it have to be adjusted each time?
3) I only sat up on the bike for less than a minute after assembling the turbo last night but I thought the rolling resistance seemed very high. I have ZERO experience of what it should feel like and maybe it loosens up after a few minutes warmup? Should the resistance be high or should it spin relatively easily (presumably by adjusting the bolt referred to above)?
4) Small issue - I already have a Garmin cadence sensor on the bike. Would it be ridiculous to fit the Tacx one on just to have cadence displayed on the computer? I'd probably be using the Garmin HRM anyway so should I also be able to get "speed" using the Garmin (based on cadance?) or does it rely on GPS
.
5) Small issue - I've removable tri bars on the handlebars and the computer won't fit on them. Should I be using tri bars on a turbo so as to ensure proper technique?
6) Setting calibration value of brake unit - Does this need to be done each time the bike is mounted due to some of the issues mentioned below? On the Tacx, does one adjust the brake unit knob (see Q2 above) until the calibration reading = 0. The Manual is a bit vague about this.Tyre slip.
Tyre pressure.
Trainer press on force.
Temperature effect on body.
Resistance setting.
Gear selection.
If magnetic trainer - what about changes in magnetic resistance, not strictly consistent.
So many variables to be controlled to have a repeatible test.
7) I'm unsure as to what the interaction between gearing, cadance and speed is with regard to Slope Resistance and Power settings but I'll probably figure that out handy enough once I start using it :rolleyes:. I'm still also unsure what sort of training I should be doing despite the recommendation to the site below. Too many choices only has me more confused
I find this site good for sessions Red + the siren that goes off at the end is most welcome
http://www.turbotraining.co.uk/turbo_trainer_sessions.php
I went on the Tacx website and it gives loads of recommended sessions for Endurance / Hills / Intervals / Recovery workouts on the Tacx Coach tab as well as fitness tests and a forum. They also have a recommended 90min workout for November. Should this time of the year be focusing on base endurance and long sessions or should intervals also play a part? I'm thinking of doing one 90min Z2 session and one 30min interval session per week plus an outdoor 2-3 hour spin. Does this sound about right?
Thanks in advance for any feedback.0 -
I will try and answer some of these questions and leave the more difficult ones for the more advanced posters - I have only the Tacx SeriusI was setting up my new Turbo last night and have a few basic questions that someone might be able to help me out on. Its the first time I've even seen one so pardon my ignorance
1) Does the new quick release skewer that gets fitted onto the back wheel to suit the Turbo usually remain there when the bike is dismounted or does one change it back to the original skewer when going back out on the road? I have to swap the skewers from turbo to bike, being honest my bike wont see the light of day until the spring so I dont have to change it often
2) Does the adjustable bolt / knob that controls the position of the brake unit and its resultant pressure on the tyre remain in the same position each time the bike is mounted or does it have to be adjusted each time? It remains in position each time for me anyways, I might have to pump the tyres the odd time but thats about it
3) I only sat up on the bike for less than a minute after assembling the turbo last night but I thought the rolling resistance seemed very high. I have ZERO experience of what it should feel like and maybe it loosens up after a few minutes warmup? Should the resistance be high or should it spin relatively easily (presumably by adjusting the bolt referred to above)? On a low setting it should spin pretty easily but when you bump up the resistance it should be much more difficult to spin
4) Small issue - I already have a Garmin cadence sensor on the bike. Would it be ridiculous to fit the Tacx one on just to have cadence displayed on the computer? I'd probably be using the Garmin HRM anyway so should I also be able to get "speed" using the Garmin (based on cadance?) or does it rely on GPS. No idea, I have just a cycle computer hooked up to the back wheel - make sure whichever way you do it that you have some type of cadence monitor on it
5) Small issue - I've removable tri bars on the handlebars and the computer won't fit on them. Should I be using tri bars on a turbo so as to ensure proper technique? We have a weekly turbo class over the winter and the instructor gets us down on the tri bars at regular intervals to get used to the position, I gradually increased the time I was able to spend down on them throughout the year as it was killing my back when i first started them
6) Setting calibration value of brake unit - Does this need to be done each time the bike is mounted due to some of the issues mentioned below? On the Tacx, does one adjust the brake unit knob (see Q2 above) until the calibration reading = 0. The Manual is a bit vague about this. No idea

What are you aiming for next year Red, that should influence what you are going to do over the winter. I am splitting mine over the winter between decent endurance spins at low heart rates and some high resistance sessions as I cant go up hills to save my life. Come spring I will start doing some vo2 max and speed sessions
Thanks in advance for any feedback.0 -
