Hi, I'm trying to remove the fork from a fairly old bike (Diamondback Traverse mountain bike) with a threaded steerer. I have removed the headset, locknut and washers, but the adjustable race is rather tight and does not appear to have anywhere to attach a spanner - i.e. it's completely circular. Any ideas on how I could remove this?
too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
One of the handiest items to keep in a tool box is a section of an old leather belt. Wrap it around polished plumbing fixtures before using pump (Channelock) pliers. same thing for your job. Protect the cup from cosmetic damage and use pump pliers.
If the threads above were distorted by the lock washer you might need a bit of force to get past them. Use some cutting oil, or any decent grease of oil and work the cup back and forth moving progressively forward with each pass until you've chased the thread back to form and it passes the bad zone.
