Thought I would post this incase anyone is looking for a new trainer. The D2R shadow is a magnetic direct trainer with a swing mechanism built in that I have had my eye on for a while.

It is not a very well known trainer but it uses the exact same magnetic direct drive mechanism as the Cyclops Silencer which is much more expensive (approx $900) and does not have a swing base.

I bought mine from Torpedo7 on sale for $370 (they are on sale at least once a month), but you can also get it from Cycling Deal or cycling express

HOWEVER, the D2R has two problems
1. The cassette is only for 10 speed, so those road riders with the current 11speed bikes are out of luck.
2. Without a rear wheel on the trainer there is not anywhere to mount a spoke magnet for ANT+ speed sensor. A trainer without speed is not very useful
But never fear, I took a punt, bought the trainer and fixed both problems.
To fit an 11 speed cassette takes two steps. First, you need to file down the small 1mm step on the rear of a Ultegra 11 speed cassette (this will make it only useful on the trainer, can't use on a bike anymore). Then on the D2R trainer you need to move one non-drive side spacer washer to the drive side and mount two washers between the cassette and frame. This results in the cassette being in a perfect position. I dont need to do any adjustments when switching from rear wheel to direct drive.
To fit an ANT+ speed sensor remove the belt cover, glue/tape/zip tie a magnet to the flywheel. Mount an ANT+ speed sensor to the outside of the belt cover so its tripped by the magnet and bingo, you have speed on a direct drive trainer.
If you already have a crank based power meter then you have everything you need to do speed, cadence and power based interval training.
