Velocite Isoflow stiffness data – class leading performance

The excellent Velocite Helios data attracted a lot of attention towards the Helios frame, so having just received the stiffness test information the time has come to shine some light on the Velocite Isoflow.

Even though the Velocite Isoflow is aimed at more comfortable riding, or harsher road conditions, it would not be correct to assume that the Velocite Isoflow sacrifices performance on the pedestal of comfort and user (rider) friendliness.

Here is some data to put the Velocite Isoflow performance into perspective. The data below are averages from seven factory tested frames. For an ultra light ISP frame that weighs just 880g in size 57cm,  the results are excellent!
