Dear All,
I need to replace a headset. Zinn's comprehensive maintenance book
suggests that you need special tools specific to that task. It is a
threaded headset.

Options:

1. Get your LBS to do it. Not expensive, minimal chance of problems.

2. Get the proper tools and DIY. Expensive but not too diffcult a job.
Cyclus tools recommended.

3. Bodge it with a home-made press or hammer or whatever. Cheap, high
chance of frustration or buggering up headset or frame.

#1 is best if it's a one off job. #2 is good if you expect to fit a few
headsets in your life and enjoy dong everything on your bike yourself. #3
can be OK if you know what you're doing, though it's more difficult with
some bike/headset combinations than others.

The special tool you need is a friend. After you've tapped the old bearing
surfaces (cups) out with a brass drift and a light hammer they hold the
frame in the exact position for you to tap the new ones in using a bit of
thick plywood, a horizontal surface with a wooden surface and a rawhide (or
wooden) mallet.

A bit of tap tap tap will seat the cups. Many small taps around the
circumference rather than one big confident bash.

Put some grease on it, and taped it in very carefully with a wooden mallet.
It went well.
Thanks for your advice.
