I'm currently restoring a 1990s Raleigh Dynatech 2070 in Castorama colours. The bike came with a Campagnolo super record headset and I want to replace with a Shimano 105 SC 1055 as is the rest of the groupset, however the height of the Shimano headset (50mm, when measured from crown race to top nut) is shorter than the Campagnolo one (76mm). When I fitted the 105 headset there was movement even with it tightened down. Could the difference in size of the bearings between both be a reason for movement?
I have a Raleigh Veloce from the same period which uses Shimano Exage 400 EX and the steerer tube length is shorter (173mm) than the Dynatech steerer (190mm). So this may need cutting down.
Any advice would be most helpful
