Didn't Hunter post on the Wattage list, about some guy (in Colorado?) who has a super-fancy rig with EKG sensors and wires that fixes one's pedal stroke and produces 'HUGE' benefits? Of course, there was no 'how', other than to say that it was expensive. Hopefully you know what I'm talking about, because I don't want to go back through the archives looking for that post.RChung said:
Dave, I have not made an effort to envelope the calibration, since I use a PT on my KK Road Machine, but maybe this post (and the associated thread) will give you an idea of what you're looking at. The intent was to determine the changes in power *during* a workout, but you can also see the variances from one workout to another. I don't intentionally regulate tire pressure or knob tension, and the temperature in my basement does fluctuate some. Those specific workouts were randomly chosen from the 3x20's I had on hand.dlinenbe said:
Dave, to be clear, I am not making any statement about the accuracy of the KK Road Machine power data.dlinenbe said:
Neither am I, although my impression is the KK is one of the only manufacturers who go through steps to ensure there is consistency. Two factors that influence that impression are that they 1) publish a detailed curve, and even a formula which describes their power curve, as opposed to a tiny .gif picture which only gives a vague idea of the speed/power relationship, and 2) sell a computer which contains the power formula and is designed to work on any one of their trainers.RapDaddyo said:
I love the Kurt Kinetic trainers, which is why we carry them. Five years on my original with an average of 1200 miles of riding each winter on my Road Machine with no problems whatsoever.RapDaddyo said:
I exclusively use rollers Kreitler Challengers (4.5 inch aluminum rollers) with the killer head wind fan (up to 1800 watts see the wattage chart below).. Kreitler are the real deal.jamesdemien said:

yeah.. i saw those... pretty awewome, super high quality! i'd love to have a resistance unit that was much quieter than the fan i have on my Kreitlers and completely integrated resistance and flywheel with no add on things sticking out.. the only thing is the amount of resistance... what do they max out at? i do 1 min intervals in the ~500W range is that possible on these? i like the platform thing too... right now i use a large socket wrenche case of for the same purpose. if i didn't have the Kreitlers already i'd be looking at these very seriously. Kreitler needs to make some sort of fluid resistance unit.. the fan is really effective but crank them up to 800-900W and you'd swear a 747 was taking off...greenrhino said:
I agree...my trainer is on permanent loan to someone who loaned it to their mother who probably doesnt even ride it...Doc said:
These or the Tru Motion rollers look really good to me. I've been riding a set of vintage Kreitler's for years and I can carefully ride no hands or stand up to stretch out (necessary for rides over about 40 minutes) but the idea of rollers that you can actually jump out of the saddle and sprint hard or rollers that let you coast a bit (or better yet both, do the e-motions have any sort of flywheel to carry some momentum?) sounds great for someone who lives in a place with winter days at 20 below zero (farenheit that is).rayhuang said:
Both the Inside Ride E-Motion and the TruTrainer look very tempting to me. Both have flywheels and resistance (maybe I should just get the flywheel and fan attachments for my Kreitler Challenger), but they have their individual features: the E-Motion has its free motion, guide wheels, and variable resistance, and the TruTrainer has exceptional build quality and folding and platform options.daveryanwyoming said:
I have a CycleOps Fluid2 that I hardly use, except for pre-race warm up, so it's a waste for me. You can save a little money by getting the kreitler dyno lyte/myte. I have the dyno lyte with the fan. I've got a double flywheel on order. Year round, I log more miles on the rollers than road. It has helped me ride a straight line when I do go on the road. I can do up to L6 intervals on it, which for me, is not that high of a wattage.rayhuang said:
I've always been afraid of that as well... The Kreitlers should be here on Friday... although its a beautiful day to ride outside...workingguy said:
I have my cheap bianchi pista(fixie) that never leaves the trainer. It has a PT pro on it and other than the occasinal loaner race bike its an ergworkingguy said:I have a CycleOps Fluid2 that I hardly use, except for pre-race warm up, so it's a waste for me.

Plus, despite my LBS's assurance that I can, I did not want to subject my super-light Ti frame to the stresses of a fixed-wheel trainer.
Only drawback is placement. It requires much more floor space and I have to be next to a wall, to prevent rolling off.
