The adapter on the spur is split in two which allows the front to spin free when the brakes are applied. The rear works as normal when brakes are applied.
Oh ok. so if I understand correctly the front wheels are already free spinning when the brakes are applied. if this is true wouldn't a front one way be a mute point since they already free wheel independently from the rear?
