The 350 Hybrid hub is built for extended eMTB adventures featuring a larger hub body and the proven Ratchet System with 24 teeth for improved durability. The increased hub flange size and larger spoke holes are designed to accommodate 2.34 mm DT Swiss spokes providing greater resistance to acceleration and braking torques. The freehub system made of hardened steel further enhances the overall system durability. Consider building this hub into your next eMTB wheelset for an extended and stress-free riding experience.Increased wall thicknessOversize spoke interfaceOversize hub shell 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 60 Cassette Body Type Shimano Micro Spline Color Black/White Skewer Included No Bearing Type Sealed Cartridge Designed for ebike Yes Defined Color Black Spoke Interface J-Bend Hub Drilling 32 Hub/Brake Compatibility 6-Bolt Disc
