Chris King 150mm ISO Rear Disc Hub: The ISO 150 Disc rear hub brings the time-tested reliability and performance of Chris King hubs to downhill and heavy-duty freeride bikes featuring 150mm x 12mm thru axle rear dropouts. These big bikes get into some serious situations but it's no concern for the ISO 150 Disc hub. This isn't a "new" hub, it's another great hub from King. Same performance. Same durability. Same expectations.
The responsibly light 336-gram hub spins an aluminum hubshell on our proven 19.5mm one-piece constant diameter axle (through the bearings to the dropouts). Our patented RingDrive engagement mechanism has 72 points of contact ensuring nearly instant power transfer while ratcheting through rock gardens, setting up for a drop-off, or pinning the final run-out towards the line. RingDrive is also responsible for that famous King buzz. Who knows, maybe you can take off your bear bell now.*
As with all Chris King hubs, the ISO 150 is completely user serviceable. Bearing preload can be adjusted without removing the wheel using a 2.5 hex-head wrench to fine-tune the adjusting clamp on the non-drive side. Thorough service can be performed on the hub bearings using a 2.5 hex-head wrench and penknife while our Hub Service Tool allows for full hub and driveshell disassembly and reassembly.
King hubs have a reputation for durability and just because this hub takes on severe conditions doesn't move us from our 5-year hub warranty. We offer the ISO 150 in 32 and 36-hole options in all 9 of our standard colors. Our stainless steel driveshell can be added to the ISO 150 for maximum durability.
* For those times that you are pedaling, please leave that bell on. For your sake as well as the bears'.
