Today was the first time of testing my new steering bearings and brake reaction stays (both sifab). The front end definitely felt more sured up in heavy braking. Little underwhelmed by the effect of the bearings. I was only slightly concerned that the steering might have felt too light when travelling at speed. But can't actually feel any difference in the steering both at speed and when slowly manoeuvring. This is no reflection on the quality of the bearings as they are quality, I'm just wondering if somehow the lower washer that connects to the axel isn't sandwiched tightly in the housing as I'm sure I recall there's some kind of circular groove where the washer sits in the axel that the washer way sit in, meaning the bearing housing is resting on the axel like the bronze damper plate used to, therefore not engaging the bearing. Either way, it's not worse, and I don't the damper blades anymore to that's one thing less to grease and adjust periodically.
I have no first hand experience of Devol bushes, but it has been noted that they grab and stiffen the feel.
