DT Swiss 240S Straightpull Boost Hub

With the DT Swiss 240 EXP Straightpull hubs, minimal weight combined with extremely good durability is something of a rarity, particularly in hub construction. The new axle system, with 15 per cent more support width, increases hub stiffness. The ‘EXP’ in the DT Swiss 240 hubs stands for the integration of the gear ring and threaded ring, which reduces the number of components and thus the weight. A single coil spring ensures faster, complete engagement and thus greater reliability. The full interlocking of the ring gears creates a large contact area and thus low point loads, resulting in superior reliability. The stainless steel ball bearings have proven to be extremely reliable and durable since the introduction of the 240 hubs. The patented freehub body operates with interlocking toothed discs. This guarantees loss-free power transmission. Straightpull refers to straight, non-offset spokes. Thanks to this technology, it is possible to achieve an ideal balance between weight and stability. The straight-pull spokes allow for very precise alignment and optimised positioning within the wheel, resulting in a stiffer and more responsive wheel.

The DT Swiss 240 EXP Disc rear hubs can be converted using optionally available freehub bodies and endstops

DT Swiss Straightpull / Spline:

• Straightpull spoke positioning: Straightpull lacing allows for precise placement and alignment of the spokes. This optimises wheel stiffness and eliminates any unwanted stress peaks.
• Straightpull hub shell: DT Swiss straight pull hub shells require minimal material, allowing them to be constructed to be lightweight yet stable.
• Straightpull lacing pattern: with crossed lacing, the spoke anchoring is designed so that the forces introduced almost cancel each other out. This increases the precision of the bearing tip and further extends the service life of the ball bearings.
