LeMond Revolution Trainer

Wed, 09/01/2010 - 8:37pm by Andy Shen

Ok, let’s not bury the lede. The LeMond Revolution trainer simulates road feel better than any trainer, roller, or ergometer I’ve tried. It replicates the sensation of flying down the road with a slight tailwind so well that it lowers the misery index of riding indoors a notch or two. And less misery = more time training = more fitness. The thing spins so well one might even say it makes indoor training (gasp) fun. (Full disclosure: we’ve done some artwork for free for LeMond Fitness' Interbike display, so you can accuse us of being cozy. But that's why I back up the review with data.)

How it works

The outstanding feature of the Revolution is its drivetrain, or how it delivers your pedal force to its resistance unit: it does away with the rear wheel entirely. You simply install the trainer as you would a wheel, and your chain drives a cassette attached to a big belt drive sprocket. That in turns drives a smaller sprocket which is attached to a wind resistance fan unit.

The fan blades are connected with a heavy ring at its perimeter, so the fan doubles as a flywheel. The fan/flywheel carries a lot of rotational inertia due to its large 12” diameter, its heavy weight, and the concentration of its weight at the outer extreme.

Wind resistance units, like fluid units, are progressive – resistance is proportional to the square of speed, so there’s four times as much resistance at twice the speed. Since you’re overcoming wind resistance while riding outside as well, the resistance curve of the Revolution matches real life resistance well. Just when you think you can spin out the entire cassette the resistance ramps up and shoots through the roof. I’d love to tell you the max wattage you can ride at a steady speed on it, but I couldn’t get anywhere near the 12 on the cassette. (The mathematically predicted steady state wattage for 90 rpm in the 53x12 is about 670 watts.)

There are several benefits to the wheel-less direct drive system. Most obviously, you don’t tear up your tires. You won’t have to install cheap tires to get through a winter’s worth of training, and if you use it to warm up at a crit or a TT, you won’t wear down your nice racing tires or gouge up your fancy skewers. Mounting/removing the bike is a snap too, as quick and easy as a rear wheel change (Cervelo-style horizontal dropouts are a bear, however. You'll have to remove the skewer completely).

But the real benefit of the wheel-less system is a huge reduction in drag. The tire/drum interface employed by most trainers adds a ton of drag, so that they give the feeling of riding through sand. That drag hurts the back of my knees as I have to fight harder through the dead spots. The Revolution’s combination of high inertia and low drivetrain drag, on the other hand, feels like you’re flying down the road at 28 mph on a set of fine tubulars. The pedaling action is much more realistic and easy on my knees. For the data and science behind trainer resistance, go here for the full geek.

See that silver spacer next to the quick release? Move that to the inside of the dropout for mountain bikes.

The downsides

The biggest negative to the Revolution is the noise level. It’s almost as loud as a vacuum cleaner when you’re really cranking. My test unit is a prototype, and LeMond is working with engineers on a shroud that will better mute the fan. In any case, noise is an unavoidable side effect of a wind unit, a tradeoff for its simplicity (and hopefully, durability) compared to a fluid unit.

Also, the Revolution doesn’t fold up. If you’re really hard pressed for space you can undo three bolts and remove the base.

Finally, it’s a trainer. Nothing beats a freely moving bike on the road or a set of rollers. Having the frame locked down feels less natural, and puts stress on the frame. The flip side is you can really zone out while you train and not worry about falling off.

So...

Despite the fact that cyclists love to wax poetic about 'suffering', riding a bike is, first and foremost, FUN. The Revolution comes very close to matching the adrenaline rush of flying down the road, where the thrill of speed helps you ignore the screaming pain in your legs. Its pedaling action mimics that ‘flying on the flats’ feeling, allowing you to train more with less stress on your joints. I for one am anticipating the winter with a tad less dread knowing the Revolution will be on hand.

Don't call your machine a Mechano-Physics. That name is already

taken.

A much better name for the Lemond trainer is a Lemond trainer.

If you continue to steal the Mechano-Physics name I'll do

something creative that you won't like at all.

So stop stealing the name and do something original for once and

come up with another original name, perhaps the idiot trainer is

best for you.

I've riding a similar version of this trainer since 1988- yes 1988. The unit I have was called the Road Machine and it has been flawless for all these years. Mine came with the very high tech 6-speed 'cluster'- pre-cassette days.

It has a great road feel better than rollers and better than fluid trainers. I have them all but nothing comes close to the feel of this machine.

If you can afford one of these you will not regret it. Be sure to find out where you can get replacement belts. That has been the hardest part of keeping my old trainer going.

Happy riding.

ANT+
Wed, 10/20/2010 - 11:28am

So will this thing ever be able to broadcast an ANT+ signal that can be picked up by a Garmin? I don't mind going 500 bucks on this trainer, but can't see droping another 350 on their head unit when I already own a 500 dollar garmin that is doing the same thing (more actualy). Is this in future plans or is it going to be an iTunes/iPod type of exclusivity thing? I think this will be a deal breaker for a lot of guys looking to purchase this unit, I would think most people looking to drop 500 bucks on a trainer that measures power probably already have power meter on thier bikes, thus own a garmin etc. already.

ANT+
By: KPonTheFly
Tue, 10/19/2010 - 12:33pm

So I understand the Power Pilot will generate and ANT+ file that we can upload to WKO+ or what not. But, will the trainer itself broadcast an ANT+ signal that can be read by any head unit (Garmin 705 for example)? Seems like this would be easy enough to do if it is broadcasting to the Pilot. Deal breaker for me, I will dump 500 bucks on the unit (I rode one @ interbike and it was great) but i don't want to spend another 350 on a Pilot that does the same thing as my 500 dollar Garmin that I already have. I feel an iPod-iTunes exclusivity thing going on here with LeMond.

You guys going to work out the Garmin native compatability? Seems like it would be a deal breaker for a lot of potential customers with the market you are going for with this unit.

My 1.5 cents...

I have these hideous continental trainer tires in bright orange made specifically for winter training on rollers or a trainer.

That with my Kreitler mini rollers works okay, except it is almost impossible to masturbate on the rollers. Easier on the trainer.

I tried an iPhone app to measure decibels, but it seemed really inaccurate. Since the test unit was a pre-production unit, I didn't want to make a definitive statement.

Not sure who makes the cassette it ships with, other than it's shimano compatible.

You obviously haven't ridden rollers or a trainer. Otherwise you would know that rollers and trainers eat tires at an alarming rate. My guess is that tire wire is at least triple on a trainer as on the road.

Just what we need - and a bit of physics chucked in to make it sound scientific. Can't they hook it up to a big fan in front so the faster you ride the more windy it gets? The only indoor trainer I have seen that looks as if it might be fun is a giant version of a running treadmill that takes more than one rider - the road rash must be awesome when you fall off the back or the power fails and you crash through the wall.

Hahaha what a load of crock.

The cycling industry constantly needs to keep reinventing itself to make money off of suckers.

Lets see first wind trainer - take front wheel off and mount fork to device with rear wheel resting on wind resistant turbine.

Second wind trainer - place whole bicycle in device and chock front wheel with anything.

Now this - remove rear wheel and mount to device.

Eagerly awaiting the next iteration of a turbo trainer...maybe something we can take both the front wheel and back wheel off and just mount the frame to.

Of course there is the good old rollers.

and what is this about tires getting worn by riding them on trainers and rollers? Don't tires get worn just by riding on paved roads?

By: Andy Shen
Thu, 09/02/2010 - 4:04pm

Got this correction from LeMond Fitness about the power feature:

As for the Power Pilot, thought I’d give you a little correction. The console has temperature and humidity sensors built in that AUTOMATICALLY compensate for changes in air density. The only other factor is altitude and the user enters their elevation when they get the unit. Default is 1000ft.

Plus, the console will have a calibration feature to compensate for mechanical drag differences between units (belt tension, bearings, etc) so you can dial in your specific Revolution to really make the power accurate.

The unit will also have a USB port and be Ant+. This will allow the workout data (HR, Cadence, speed, power, etc) to be collected via USB stick or Ant+ enabled watch and uploaded to TrainingPeaks or other program. Another cool feature is that the unit will also allow you to UPLOAD workouts to it that are based on power zones, % threshold power, HR zones, % threshold HR, etc. All you have to do is increase or decrease your cadence to work in the designated zone as indicated by the console. No more referencing that printout from your coach…. Console beeps, shows you your goal and off you go…training and collecting your workout data. We plan on shipping the unit with a couple of programs pre-loaded...

Let me know if you have any other questions about the Power Pilot. It should be ready for sale before Thanksgiving.

no power tap needed
By: LR
Thu, 09/02/2010 - 11:03am

You don't need a power tap with this. Unlike riding on the road where you have lots of variables contributing to resistance, riding the training only has one, the fan. So the manufacturer could just print a chart that you could use to figure out power.

Lemond should use a duct on the fan to blow the air straight at you while you ride, similar to what Kreitler does with their killer head wind unit.

I just checked the Lemond web site and it looks like they will have a power display unit with download capability available this winter.

Folding to a flat package would be a big plus.

$500 seems quite steep for what is basically a wind trainer.

Love the idea, great improvement. If not to late to modify design slightly it woulb be nice if they funneled the air up the rider's butt for a nice cooling effect, with a top vent like Kreitler's killer headwind does:
http://www.tandem-bicycle-central.com/image-files/headwind.jpg
At least all those watts wouldn't go totally to waste if they saved you from having to put an electric fan on to cool off. It might make it less noisy too by allowing the air to escape.

this device has been around at least 25 years, nice updated version with Lemond Fitness. As real feel as it gets especially for intervals/accelerations/sprints inddors, thats why the AUSSIE track team loves a similar device (BT Bikes Trainer)...end of the day, if you have rpm/hr/power numbers from your current trainer, not a huge difference in training effect for steady state effort.
E=Motion, "Inside Ride", rollers are by far the most road feel and skill...you actually ride your bike in or out of the saddle, steady state ir full sprint...just now light or foldable, so storage/portability limitations...

Emotion rollers are great. We own a set. They have a two layer system so that you don't fall off if you accelerate or slow since the inner frame is suspended and can move forward or backward to accommodate shifts. Also, there are bumpers (they look like rollerblade wheels) so you don't slide off the sides. The motion is nice and there are different resistance settings on the drums.
