Tacx Antares Rollers and small wheeled bike

othello

I've picked up a set of Tacx Antares Rollers for my son who has a 24" wheel track bike. The manual is pretty slim (to put it mildly) and I'm not quite sure I have it set-up right. :?

I've released the grey levers and got the drums in the right position so that the front axle is directly over the middle of the front drum. The screw stops underneath don't line up to anything, but they are only for marking the open position, and I've stuck a bit of tape on the arms to mark the length.

But...

With the arms in the right position the belt is too slack (belt is usual position around the front drum and the first one at the back). So to get the tension I've stretched the belt over the last drum at the back -- the belt runs from front drum to back drum. Is that OK? Or am I missing something on the set-up?

The distance between back and front rollers can be adjusted in 7 steps. This allows for the use of bicycles which have as maximum 1100 mm as distance between centre of front and rear wheel and as minimum 960/980 mm between front/rear wheel centre. This is determined by moving screw in fittings

What is the measurement axle to axle of your sons bike?

Axle to axle is 86cm, but I've seen other kids with similar bikes get it to work.

Here is my sons bike on it for info.

so you have not located the pins but are using it part collapsed for storage, probably work OK, but you might need to put something non slip behind the grey levers to add to the clamping strength to stop it slipping.

Or increase his protein and get him onto 26" wheels

Yes, the slipping is the problem, because the band is really taught.

I have seen the pins in the bottom but I *thought* they were just to act as guides for when extending out? They don't go through one arm into the one inside to clamp it. I might have to drill a hole!

He will be going onto 26/650 wheels in the New Year, so not long to wait
