building bike solely for trainer(8 posts)

I'm putting together a bike solely for use on a Computrainer. I'm thinking of a 5 year old steel Bianchi Alloro and a heavy MA3 rear wheel with super heavy thornproof tubes and heavy tire. Any more suggestions for building a beefy bike that will spend the rest of it's life on a trainer? Thanks.

So you DID get the Computrainer!ColnagoFE

My wife would kill me if I spent what you must spend on bike stuff. I mentioned a C-40 the other day and she just rolled her eyes. I use my Bianchi Eros on the trainer though I mostly train on my Johnny G Spin bike these days. Put on some wide cheap wire beads and they will last forever. I have MA40 rims but really the trainer doesn't beat a bike upm all that much assuming you mostly spin in the saddle.

It's supposed to be here tomorrow. I have a computer with 19" monitor lined up for it, super industrial fan on a stand, positioned under ceiling fan in spare bedroom (not garage this time), TV with built in VCR; in other words, a dedicated training center, sort of.

Since the Computrainer allows you to record a ride, I'm going to invite friends stronger than I am to come do a session on it, then I can race against their stored ride; it simulates an opponent based upon the recorded ride. That's the plan, at least.

Then I can be home while riding, not have to worry about flat tires, lights, safety, and take care of the little guy if necessary. That's the plan, at least.

can you race against "on-line" opponents with that computrainer thingy???

The first thing that comes to my mind is rustproofing. Even with yur industrial fan, you are likely to drip a lot of sweat onto the bike, which will collect under cable housings, etc. So, you might want to take some steps to prevent that.

Sounds like a cool setup you will have though. I'm thinking about building up my old Klein frame as a trainer-only bike, since it's aluminum & won't rust.

Hi Doug,

Congrats, you will like it!

My coach has a setup we all test on periodically.

Some of the things I have noted:

Skewer can be a situation--the trainer may prefer a certain size/etc.

Mount the trainer on top of a solid flooring--my coach uses a sturdy, laminated banquet table. Sweat can be wiped up, and the trainer can then be set on its side for storage. Provide a very stable platform, protects the flooring too.

If you go with the table, use towels under your bike too to catch sweat and prevent slipping when getting on/off the bike.

Perhaps build/set a table that is within easy reach so you can set stuff, like extra water, remote controls, phone, or whatever next to you so you can safely and easily get them.

That's all I can think of....have fun!!!

Doug, I have a computrainer and would recommend the following not listed items.
1. Slick tire on rear wheel. I use an Axial Pro and it lasts the winter and doesn't slip on steep climbs.
2.Sweat Net like the one sold at Colorado Cyclist
3.Old QR Skewer (Steel) for back wheel. The stand will chew up Aluminum.
Have Fun,
Stoutga

I got a 3D computrainer this spring and I suggest:
1. Buy a little electric fan to blow on the rear fan/resistance unit of the Computrainer to avoid overheating it. Cook this and you will have to replace it at a cost of $400.00.
2. You don't need "superheavy" rims or thorn-proof tubes. You do need to read the directions and "calibrate" the resistance at or near the default reading of 2.0 If you calibrate too high, you greatly increase the risk of rearwheel tube blowouts!
3. The directions include "plans" on constructing a stable platform.
4. You can compete against another person "on-line"!
5. You don't need to have another "faster" person ride a course and then save it so you can compete against this. The Computrainer has a "robot" rider that you can calibrate to ride any course at any watt level. You then can compete against this "live" or in saved function. You can also compete against your previous performances.
6. The video card in your computer should have the latest driver for best performance. Go to the websites of ATI or Nividia and download these drivers.
Enjoy the ride!
