I’d love to read this whole article but very interesting and I have a feeling this can be backed up totally by Jan.

Off The Beaten Path


In the last issue of Bicycle Quarterly, we compared the performance of a 17-pound titanium racing bike and of a 26-pound steel randonneur bike. We were surprised when both bikes climbed at the same speed in a set of controlled experiments. Others shared our surprise, but added: “That cannot be true. Physics require that the heavier bike climbs slower.”

Having ridden the bikes myself, I know that their performance was evenly matched. And as a scientist, I also know that this result does not contradict the laws of physics.

Our critics assume a constant power output. If we always put out 600 Watts during these climbs, then any added weight will slow us down, all other things being equal. And an extra 9 pounds is significant enough that it should be measurable. There is little disagreement on this.

And yet the two bikes did climb at the same speed, despite…
