Turbo up for grabs, Elite Volare Mag Alu.
I've used this for Trainer Road, and it seems to have a sensible power curve.
Turbo has a remote adjuster, but tbh I've always left it on max and used my gears to vary intensity. You can put a fair bit of effort into this unit, but out of seat efforts may over-power it depending on your strength.
As an example, my glorious sprint for the line at the end of the Tour of Sufferlandria saw me maxing it out (admittedly on a compact with a big cassette - gear was 34/13) producing 570W at 150rpm and an apparent 82kph.
For your normal, everyday suffering this turbo is fine. I only changed it because I won a Kurt Kinetic in the ToS.
Any takers at £50?
