Hi Stephen,
I actually thought about that - does not appear to be so easy.
The Bronze/brass ring is press fit into the arms which are not
exactly the beefiest of aluminum casting of forgings (hard to
tell which). Finding a bushing with correct id, od and length -
even by scrounging from otherwise defunct Mafac model that had
them and then press fitting to a Racer to get longer arm and
easier straddle cable situation might work. Feels like too much
work and a bit risky. Anybody tried it?
