TYPO: The headings of the chart at 07:25 should read 50-80% and 80-95% for worn roads and chipseal, respectively.
As long distance cyclists, our hands suffer. Vecnum have a solution they hope results in the best performing suspension stem available. While their target use case may be gravel and ATBs, I believe their use of elastomers and a linkage system make it ideal for the road and aero bars use. Here are my first impressions and the first publication of a comfort test protocol I'll be using moving forward. Enjoy!
