Nimbus Oracle Universal Disc 36" frame is a special frame that is designed for 100mm wide hubs with a brake mount option on both sides.
Unlike other 36" Oracle frames this one is designed to fit 100mm bearing spacing. This means that it will fit hubs with 100mm pitch with 42mm bearings. This includes the Nimbus ISIS Disc Steel Hub, Q-Axle hubs, KH Spirit hub or the KH Schlumpf geared hub. In particular this frame is designed to match the fantastic Brakefast Schlumpf Brake Adaptor.
This frame comes with the ability to fit disc brakes on either side. This would allow you to use the Kris Holm outboard disc mount system or the more common inboard disc... or even both at the same time!
