Re: Should I buy a new hybrid bike ?

Hi Sarah,

Sorry I don't know much about any specific suspension systems. Any suspension system is going to add some weight to a bicycle. In order to cover the cost of a suspension system a bike may use lower quality components elsewhere. It's largely a matter of balance - are all the components of about the same level of quality; better quality components tend to be lighter and/or last longer. Some suppliers provide higher quality components on the more visible parts of a bike and lower quality components elsewhere (e.g. wheel bearings and bottom bracket).

As far as tyres go, I can comment on that. Knobbly mountain bike tyres, especially if not inflated very hard, can result in an energy loss of as much as 15%. Narrow racing tyres (around 25 mm) have very little energy loss but are usually inflated so hard that they do nothing to cushion any bumps in the road, and are not really suitable for off-road use. Hybrid tyres (35mm or 38mm) are a compromise which allow mild off-road use but which are reasonably efficient on-road, and which provide some cushioning. Tests have shown that road grip is just as good for smooth tyres as for those with a tread, but a moderate tread may be better for mild off-road use. I have tried tyres which have a smooth central portion and noticeable tread on the edges, but found these personally unsatisfactory since when I lean over on a fast corner the handling suddenly changes dramatically as the tread contacts the road.

Transmission efficiency (chain and sprockets) can be drastically reduced if things get rusty - regular mild lubrication is better than very occasionally flooding the chain etc.
