'Rolling Roads'
I want to get hold of a 'rolling road' for cycles (i.e. where you place
your bike in a frame, the front wheel is stationary on the ground, and the rear wheel moved on two cylinder). Could someone provide me with the correct name for this piece of equipment, and where I could buy one? Many thanks... |

I gave up on it from boredom after less than half an hour's total use ;-) -- Tony "Don't argue the matter, the difficulties will argue for themselves" -W.S. Churchill |

The second is what's called a 'turbo trainer', where the bike is clamped (usually by the rear skewer) into a sturdy frame which keeps it upright, and the rear wheel rests on usually only one roller. This is much easier to use, and much safer, ~~~~~~~~ it can be pretty lethal for the rear traingle of a modern lightweight frameset -- --- Marten Gerritsen INFOapestaartjeM-GINEERINGpuntNL www.m-gineering.nl |

I was wondering that. If the rider's centre of mass is fixed relative to the bike, I cannot think of any difference. However, if the rider's weight shifts from side to side while pedalling, a normal bike will simply lean to compensate, while one fixed in a trainer remains upright and the stresses on the right and left sides of the rear triangle will oscillate. I've done no sums to find out if this could possibly be significant. -- Joe * If I cannot be free I'll be cheap |

I can't see how the axle pivoting in the clamps of a turbo trainer would cause forces that would not be seen during general riding/cornering? So what if the axle is loosely held. Mind they are expensive in terms of rear tyres, you're best bet are the cheapest tyres money can buy. |
