General information about our shipping
Much lighter than a standard tube and more reliable than latex. They don't leak and go down while not in use. Can't rate durability yet as they have not been in long.
Fragile but if you prefer clinchers these are great. Just be patient fitting them. You really notice the drop in rolling resistance.
Came out as stated weight, to note they are thin and best used for race days and your best wheels. Not had to perform a repair yet and we will see how they hold up. No problem to fit and they are "shaped" as per label, just be extra careful not to pinch them. No noticeable difference in the ride quality though For general use would probably stick to the race version, i have them on my commuter and no problems. Top service from Merlin
