Strummer HM-350 Gen-2 HG-MTB 6-Bolt Hub
QR 9×100 / 10×135 mm – 114 POE
The Strummer HM-350 Gen-2 is an MTB hub with a built-in Quick Release 9×100 mm front and 10×135 mm rear standard. This hub uses a 114 POE engagement system with a 6-pawl, 3-tooth mechanism, providing a fast and direct pedaling response.
Compared with the HM-350 Gen-1, the Gen-2 version has wider pawls, providing a larger engagement contact area and stronger construction. Its internal system is also designed with lower rolling resistance, making the hub feel lighter while coasting and more efficient when the bicycle is moving without pedaling.
The hub body uses AL6061-T6, while the axle uses AL7075-T6 to balance strength, weight, and durability. This hub uses a 6-bolt disc brake system and is compatible with an HG-MTB cassette.
