Race 30K4 Lefty 29" rear wheel

Wide, robust, and ready for every trail! The Race 30 (Flow MK4) Lefty 29” is the ideal companion to enjoy on your home trails. The weight of this wheel is as low as possible while still keeping in mind and focussing on durability. You can match this wheel on a Cannondale bike with an offset of 3mm for boost hubs. The wheel is equipped with our best-selling ClimbHill hub. The hub is CNC machined in our factory from aerospace grade aluminium, thus demonstrating increased fatigue strength and low weight. The anodising ensures a great look and prevents corrosion, even under the toughest circumstances. Assembled and adjusted by hand in Buggingen, Germany, the Race 30 (Flow MK4) Lefty 29” boasts the highest quality standards—guaranteed! The geometry has been optimised for a balanced, stiff wheel. The hub is finally fitted with double sealed endurance bearings and a reinforced freewheel to ensure flawless reliability that can brave any kind of pedal kickback. The Flow MK4 rim from Stan’s NoTubes is made with high performance aluminium alloy, which confers competitive weight, great ride stability, and the best durability on the market. It is asymmetric for a more balanced wheel build and shot peen finished to increase fatigue life and durability. With an inner width of 30mm, the rim provides improved tyre support, which allows lower pressure, less rolling resistance, and better grip on rough tracks. It is ideal for modern trail assembly. This wheel is completed with D-Light spokes from Sapim, which are mounted with Secure Lock nipples to maintain the spoke tension over time. The wheel is available in all the Tune colours, so don’t hesitate to take advantage of giving your Cannondale bike a pure look. The next time you cannot shuttle, you will enjoy the limited weight of this wheel, and the next uphill climb will not feel like such a chore! So, get on your bike and SEND IT!
