Is there any other trainer on the market that create very high resistance besides the cateye(slocom) in the normal trainer cost range?

Kurt Kinetic gives big resistance at high speeds. Check out the chart at the bottom:

For starts it doesn't have entirely realistic resistance, but they have a "Pro" flywheel option that makes it better.

Some people use 3M traction tape on the roller to keep it from slipping in sprint efforts. I took mine apart and had the roller knurled. Dropped 1800W today with no slip!

A Continental Trainer tire with alcohol works fine, too. I've put 2,000W into a Cateye during a standing start effort using a continental trainer tire. The key is to get the gearing plus resistance setting right for it to feel like the real thing.

The problem with the Kurt fluid trainer is that you have to build up speed to get resistance, which leaves you at less than 100% when you are at the target resistance. You can't get instant resistance as in a standing (or slow rolling) start. You need a mag trainer to do that.

I have the Kurt mag trainer with the optional extra flywheel. I use it on it's highest setting and it's still not enough resistance for me. I'm at 1 notch under the highest setting on one-legged efforts. I'm back to using my Cateye. I'm happy to have it.

I'd be interested in finding a modern mag trainer that offers high resistance, too.

Yes exactly. The Kurt Kinetic is ok for flying but not even close for the low end stuff. I guess nothing exists in a normal trainer

Maybe the CompuTrainer and a Slocum stand?

53x12 and the heavy flywheel is pretty good, IME.

Just curious, what sort of top-speeds can your guys get with the small FW?

[velodroom]

Of cause the mag based function of the Wattbike.

For a 2500W sustainable effort is a torque needed in the range of 159 N.m. in combination with 150 rpm.

I happen to have a device, which in terms of torque at least theoretically goes way beyond the figure of 159 N.m.

Torque behaves approximately linear with rpm, when mag based. So you can calculate.

The instant load is so high, that you have to be mentally prepared.
If not, there's a good chance you come to a halt.

But the likes of Chris Hoy train with a device, which creates up to 700 N.m.
They don't tell how much speed and wattage they achieve in this situation.

Velotron?

Wrong question - the question should be "how quickly can they accelerate it?"

I'd need to go back over a heap of power files from last winter's ergo program to find out, and I'm lazy

Hey Jon,
With my Kurt Kinetic (smaller flywheel) and 3M tape I usually see around 40.5-42 mph which according to my Powertap ends up around 1650-1700 watts.

It's really nice for even standing starts because the resistance comes on fairly quickly so that you are struggling with a second or two. No wheel slip occurs for the first 6-7 efforts so your best workouts. After that I believe the "grit" on the tape seems to lose some adhesion and you start to smoothen the area where the tire comes into contact with the roller.

Dan
ps. I thought on the Kurt Kinetic site there was a retrofit for the normal Kurts to accomodate a larger/heavier flywheel.

With the small FW, it is near instantaneous I'd think. Last test I managed 70.7 km/h. Must be my box-jumps

If you pull the thing apart and bring the roller to a machine-shop and have them knurl it your 3M tape and tire-dust days are over.

A conti trainer tire and rubbing alcohol to keep it clean works fine. A lot less effort and lots cheaper than replacing street tires.

I've used the same trainer tire since 2009.

The only down side is that they are very difficult to mount/dismount.
