350 Dependable Independence - Reliability versatility and simplicity united in a hub. The 350 hub is a dependable partner for every adventure either with its 36 tooth proven freehub Ratchet system or the fast engaging Ratchet DEG system with 72 points of engagement. The sophisticated yet simple construction of the hub allows a low weight while providing outstanding rolling performance. Furthermore it enables cyclists not only to maintain their freehub system without special tools but also to convert to the various standards. The intention behind the 350 was to create a dependable hub that supports cyclists in their independence.Achieving a different engagement angle from what DT Swiss has done to date required a major adaptation to the drive side of the hub. The Ratchet DEG system and its new hub body allow the installation of size-optimized 72-teeth ratchets at 5 degreesMade of steel the DEG ratchets are bigger than all the previous DT Swiss ratchets and aim to transmit the power of even the strongest riders for a long time and across a large contact surfaceThe innovative construction of the 350 DEG hub allows bearing replacement without special toolsCompatible with 90t DEG service kit sold separatelyApproved for use with ebikes (max. 32Km/h or max. 250W) TECH SPECS table{border-collapse:collapse;width:auto;max-width:100%;} td{text-align:left;padding:12px;font-weight:350;word-wrap:break-word;} tr:nth-child(even){background-color:#f2f2f2} th{background-color:#eb212e;color:white;text-align:left;padding:8px;} .desc .specs-heading{font-size:24px;font-weight:600;padding-top:35px;border-top:3px solid #f0f0f0;display:inline-block;border-bottom:4px solid #eb212e;width:142px;margin:0;} Rear Axle 12mm Thru x 148mm Tooth Count 72 Cassette Body Type Shimano HG Color Black Skewer Included No Bearing Type Sealed Cartridge Designed for ebike Yes Defined Color Black Spoke Interface J-Bend Hub Drilling 28 Hub/Brake Compatibility Center-Lock Disc
