I upgraded the group set on my gravel bike and decided to go with the Silca Nastro Cuscino 2.5mm. The 2.5mm besides looking great on the handlebars is just the right thickness and also does a super job damping the road vibration. It's everything and more than what's been said of it.
Feels good, wears good, looks good. Yeah it�s pricey. But quality ain�t cheap.
