Concrete and Rebar: Rollers
So I am looking at eMotion vs TruTrainer reviews all over the place as I want to get some rollers for this winter, smart rollers.
I like the flywheel that TruTrainer has. I have ridden them in indoor competitions before but I have never ridden the eMotion ones. The flywheel gives an incredible real road feel to riding rollers but it's still tricky to get up and sprint. Seems like the eMotion ones have that locked down but they don't have the flywheel. That got me to thinking. It got me to thinking about my current rollers. If I fill the rear roller with concrete and rebar and or ball bearings or something like that do you think that would mimic the TruTrainer flywheel? We can also make this a TruTrainer vs eMotion thread too. I'd love to hear from your personal experience on either one of these. Regards. |

Some rollers have an "accessory" side for a belt driven fan (headwind maybe?), perhaps you could rig up a flywheel in that manner.

So... Shimano vs Campy, or at least a bit like that.

Yeah I figured this would be a Ford Vs Chevy kind of thing. They both have pluses as far as I can tell with no minuses. |

Why would you put rebar in the concrete?

Filling it with concrete and rebar seems like it would be difficult to balance-- could cause vibration/shaking issues. Plus, it's relatively permanent and difficult to try. I don't know what the inside of an eMotion roller looks like, but it seems if the bearings are sealed off you could just fill it with sand to try it out. If it doesn't work, clean it out and you're back to normal.
However, I think there's more to this than just adding inertia to your rollers, otherwise why would TruTrainer go to the trouble of adding an internal flywheel when they could have just made the roller heavier. The flywheel smooths out/dampens the loading and unloading, in addition to simply adding inertia. I'd be more inclined to try to mod the Tru-trainer frame to add the eMotion features if you must.

I just wanna' know if the nice TruTrainer "accessory step / platform" can work on the InsideRide smartrollers!

That I have been thinking about too.

Here's another polite request for a posted video if you end up making this. I am interested in how it would turn out.

The reason for having the internal flywheel is so they can offer the option of disconnecting it, when you choose to rider TruTrainer's as standard rollers. I have TruTrainer rollers. One benefit they have over the eMotions is they hold the wheels level to the ground. It feels more comfortable and natural riding in the drops. On standard rollers, where the rear wheel sits slightly lower than the front, I tend to use the tops of the bars more, otherwise I feel undue pressure in the private parts area. I don't worry about the inability to sprint. That's such a minor quibble to me as not all rollers can be all things to all people.

Thankfully, at this stage of my life I've learned the cheapest way to do something is buy/do it once. I have some good equipment that I've long forgot how much I paid for it.
