Assembling Turbo Trainer

[maklabouhlel]

Hi everyone. I'm trying to assemble my Tacx turbo trainer that needs to be assembled according to the wheel size used. I'm planning on using my road bike which has a 700c wheel. The three positions on the trainer are:



I was planning on assembling it in position 2 but aren't 700c wheels 622mm diameter?

I could only get the roller to touch the tyre in position 1 or am I doing something wrong?

You sure it's position one and not three? It's the one which makes it closest to the roller. The other positions are all too far away.

It turned out to be position 2 (race tyre) as suggested in the Tacx forum. Thanks anyway.
