One of the lightest alloy clinchers available at only 1240g. An aluminium racing clincher that is perfectly capable for every day training rides. The rims are Stans No Tubes Alpha 340 which feature the BST which improve sidewall strength, increases tyre volume and is compatible with tubeless tyres. The tried and true Stans rims means braking is consistent in all weather conditions and the bead seat helps improve impact resistance. As knowledgable riders will know stiffness doesn't come from fluffy soft toys or daily prayers but real life quantitative figures. Extralite uses straight pull, triple butted bladed spokes and the hub flanges are pressed right out to the outside for maximum bracing angles - both front and rear which radically increases lateral rigidity. Combined this with a high spoke count of 24 + 28 these wheels have a real sharp snap when putting down the gas. A very solid climbing wheelset but also equally good in breakaways, the high end Extralite SPX/SPM hubs feature a unique bearing preload system and low friction seals that keep these wheels spinning...and spinning. The Micro-Tuner bearing preload is really easy to use and means you can get bearing preload set accurately each time also reducing bearing friction. Stiff and light on the climbs and silky smooth on the flats.
