I have just built up a steel frame with new carbon fork and headset. Problem with Steerer Flex. If I setup the bearings to be 'just not loose' as soon as I sit on the bike the steering binds. Once loosened off to allow normal riding it stiffens up when braking. Rather disconcerting. I'm wondering what my options are?
1. Mess about with a different headset with more compliance.
2. Fit a nice custom steel fork (tried a cheap one, no problems) or carbon with steel steerer (do these exist?)
3. Take it all back to Spa and complain (anticipate 'well no one else has...)
Just for info it is a big frame, 200 mm between bearings, rider weight of 75kg
