Bicycle Fork Steer Tube & Bottom Bracket Re-threading: I have: 1 x 24 re-thread die, 1 1/8 x 26 threading die and a 1.375 x 24 BB re-thread die set to thread/re-thread/clean up Headset & BB threads. Therefore I can re-thread older 1 x 26 road fork steer tubes to 1 x 24 in order for one to fit new 1 x 24 headsets with caged bearings, thread 1 1/8 MTB threadless fork steerer tubes 1 1/8 x 26 if one wishes steer tube to be threaded for 1 1/8 threaded headsets and re-thread older (Raleigh) 1.375 x 26 Bottom Bracket Shells to 1.375 x 24 in order for one to fit bottom bracket 1.375 x 24 sealed cartridges. If you are local this is an inexpensive choice to repair bike frame as I would only charge a labour fee to re-thread fork or bb shell. This is a labour ad, NOT a sales Item ad.
