1" steering tube fork on newer bikes(4 posts)

1" steering tube fork on newer bikestrimble
Jun 24, 2001 8:14 PM
I have a Kestrel EMS fork (1" steering tube)w/Cane Creek headset. I'm intereseted in upgrading to a Ti frameset, but most bikes these days use 1 1/8" steering tubes.

How can I salvage my Kestrel fork to use on a newer frame?

if you dont already have a headset or are planning on getting a new one Chris King makes a devolution headset that presses into a 1 1/8 frame but uses a 1 in Crown race ( king calls them "base plates") or you can get a headtube reducer that presses into the frame before the headset cups ask your LBS about these two options.

I use the QBP Problem Solvers Head Tube Reducers on one of my bikes. It was the most economical way to use a RockShox Ruby SL road fork on a modern aluminum frame.

Just press the black anodized aluminum reducers into the frame as if they were headset cups and your 1" fork and headset should mount up fine.

No complaints, but I'm not sure how I would ever get the headset cups out of the reducers if I disassembled the front end.

Any decent bike shop should be able to order these through Quality Bicycle Products.

My old C-Dale has a 1-1/4 headtube, and you can't find forks OR stems for it. The reducer is a couple of aluminum rings that press into the tube so you can use 1-1/8 stuff, and I'm pretty sure they make them in other sizes.
Warning: They're WAY overpriced, I think $40 a couple of years ago. But the alternative was to throw the bike away...
