Chopping of a HT extension

Tailwinds · #1 10-19-2006, 11:03 AM

I'm looking at a ti Serotta that would need to have the headtube extension removed for it to fit me. Who would I contact (preferably in the Denver area) to do this, and how much might it cost?

I don't know about the head tube butI know it will have some nice wheels.

steel or Ti , steel being the easiest to chop off , go see anybody at Wheatridge or Chris Jacobson's shop , my bet though is take it to Lennard Zinn and he'll do it for you .

If you can't find anybody local, try Ti-Cycles.

The ideal way to handle it is to have the extension sawn or milled off (best method if the headtube can be fixtured in someone's mill), then the top refaced with a headset facing tool, and the inside refinished to ensure it's nice and round, etc. I was quoted $50 to have this done on a frame, regardless of whether it was steel or ti. Paint isn't an issue if it's done well -- it doesn't flake off the paint or anything like that. You could check out builders from

just to get some names. A dedicated custom builder is the safest way to go, but if you have a good referral on a local builder or high-end shop, I've had good experiences that way as well.

I did this to my CIII. I did it with an experienced mechanic who really knew what he was doing. We just milled it down with a facer and lots of cutting oil. It is steel.

Let an experienced mechanic or framebuilder do this because having it done wrong could well ruin the frame.

2 Minutes with a hacksaw and 5 with a facing tool and it's a done deal.

Don't you have to have multiple personalities to do that?

my friend lopped a couple of cm off his peg love 3 with a hacksaw and then took it down to the shop to get faced.

i was horrified watching him do it, but it worked out fine.

measure twice...

A hacksaw wont cut it with Titanium though , I think you'll need a special blade and some power behind that force. Go see Lenard Zinn , he's in your neck of the woods .

For us unskilled labor types, how do you make sure you get a straight cut? I have a fork steering tube guide cutter thing.
