Tune-thru-axles - are in a class of their own - a super light axle with huge clamping force, unique and sleek designs with no sharp edges to avoid injuries. The newest (superlight) through axle skewer created by Tune is the Skyline U30. It consists of a carbon-aluminum axle meaning that it is ultra light weighting just 29 grams but also super strong. It provides a stronger link at the bottom of the fork, thus ensuring a more stable front. In addition it ensures that the wheel has always the right position, in addition to this it is lubricated by a patented anti-friction coating which offers enduring, reliable function. The anti-friction coating enables adjustability of the quick release lever in closed position.
