General information about our shipping
Weight weenies dream.... fitters nightmare. These are so thin, great care needed when fitting but they are worth the hassle. Worked faultless on my Fulcrum 3 with Ultremo ZLX tyres, for an ultimate light weight set up.
Super light but hard to put in. Must apply some powder on inner tube and also inside the tyre as well. Otherwise it may stuck between tyre and rim and probably puncture. Definitely recommend it, if you have got no-name inner tubes, and using moderate puncture resistant tyres.
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
