I frequently ride my gravel bike on mixed terrain routes along the Andes with substantial amount of pretty gnaly surfaces, and felt like I needed a little more suspension on top of 2.1" front and 50mm rear tires to at least alleviate physical burden being caused by merciless vibration.Not a cheap investment, but so far it has convinced me this purchase was a great call.This thing works great especially when I am forced to stay seated on my saddle as I pedal hard uphill. One of my favorate route has single uphill segment that lasts more than 60km and 2000 meter elevation gain.Being able to stay more on my saddle really helps save my legs which makes me ride faster and further.I have wrapped it around with plastic wraps to protect it from dusts and experiencing absolutely no squeaking noises after hundreds of miles.
