DT Swiss 350 Boost MTB 32H Hubset

With DT Swiss’ new 350, reliability has never been more important. This new state of the arch Swiss technology fits perfectly in the centrelock rotor to make sure it remains safe and intact. Its 32 holes with a 6-bolt Disc relies on the strong materials used to create it. Although a small part its clever details reinforce the transfer of the highest of loads and make it more aerodynamic, so you don’t need to worry about bulk. Able to withstand the tension of the strongest pedaling power, the 350 gives athletes reliable direct power transmission.

Competition Spokes

This is one of the most versatile spokes in the DT Swiss spoke range. DT Competition gets its special strength from cold forging. This makes it not only extremely durable but thanks to the thinner middle section, it is 48 g lighter than a spoke with a constant diameter of 1.8 mm. The balanced relation between strength and weight of its 2.0 mm counterpart allows for a wide range of uses, from road wheels to super-light Enduro MTB wheels. Weight: from 311 g for 64 spokes at a length of 264 mm.

Squorx Prolock Nipples

Pro Lock is a process where a dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Re-truing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.
