This is a tool I used about 15 years ago when I built my Cannondale road bike. I found it again recently and have no idea what the hell it does. I believed it was a crank puller, though now that I look at it it definately isn't.

It's two parts and the smaller end of the bigger part is threaded, though it doesn't fit anything I can find.

Anybody?

Thanks!

Can you insert the photo into a forum message?

I've attached the photo here so people can view it without having to login through your provided link.
EDIT: okay, thanks for attaching the pic to your OP.

That all said, I don't know what it does either.

Ah, got it in there. I guess that is what it means to be noob.

MudPie

I'm still scratching my head. Can you give some lengths/diameters?

It looks to me like it might be used to clamp a BB fixed cup tool to the spindle/axle. Just a guess.

Will it screw into the derailleur "hole".I wonder if it is some sort of alignment tool?Luck,Charlie

isn't it used to help seat the headset bearings?

jimn

Might be some sort of alignment tool for the derailer hanger. I'll check that, but I remember it being part of the crank/bb tools. Also, those Cannondale hangers didn't really bend, they broke! This was before the era of replaceable ones. Now, I remember this because the road bike in question had a broken hanger from an accident. Could this be a clue? I search my memory.

Cannondale did eventually give me a new frame.

This thing's about 2.5 inches long, and the wide part is just under an inch. The threaded part is maybe 3 8ths of an inch. I don't have it here in my hand to give more accurate mesaures, but I will get them tomorrow.

cascade168's answer strikes me as the most likely.

Another thing, though, is that I believe my bb spindle was a "male". I may be completely crazy, but I seem to remember the ends of the spindle having bolts and the crank arms being held on by nuts, which I have not seen on more recent square-spindle cranks.

jimn

bunabayashi, how so? Don't you do that with a hammer and a 2x4?

Bockman

I dunno, I seem to recall a special tool for seating the races... does the diameter of the shaft match your headtube?

What kind of freehub system did you have on the Cannondale? Looks like a freehub removal tool.

cascade168

Not crazy ;-) See pic.

It looks like a part of a rear derailluer hanger alignment tool. You're missing the piece to align it with the wheel.

Roll'n Thunder

Looks like an install/removal tool for spline drive cranks.
Profile (and some others) use a tool that looks exactly like that.

jimn

I should say that this tool
1) is at least 15 years old and
2) posesses no teeth or threading except that you see on the end of the long bit (or would see if the photo were better).

Doesn't that rule out spline-drive cranks?

The freehub system was pre-cartridge, screw-on kind. Fairly sure this wasn't for that, because I remember taking it to City Cycles on Broadway in NYC to get the freewheel loosened. I know the tool you mean, though, I think, and the smaller piece does look like that. The smaller piece is just round, though. No teeth or threading or anything.

shiftinjon

Actually, 15 years ago, freehubs were around, as were freewheels, so you could have had either. It is unlikely that you would have a freehub removal tool though as most people would never have a need for it. I don't remember if Cannondale was branding their own parts then though, but the larger part looks like a freehub remover and the smaller part looks like a sleeve to fit beween the remover and the ID of the freehub body. Are the threads left or right hand? A pre-96' freehub remover:

jimn

shiftinjon, would that thing have threads on its slimmer end?

shiftinjon

The Dura Ace remover in the picture I posted does not; it is a splined remover; but there are other types.

Svr

It's a Profile Racing cro-mo crank arm install/removal tool.

jimn

Good God Man! You are correct!

Ok, I imagine the threaded part goes into the spindle and pushes the arm on?

How on earth would this help you remove a crank arm, though?

shiftinjon

Cha-ching!

Svr

Remove the crank bolt, install the tool without the sleeve, then tap the hex end with a mallet. This will push the spindle out of the arm. Profile uses a floating spindle so it will slide easily out of the bb.

i was going to say that it was some sort of driver because i didnt see any threads & it looks similar to a bushing driver

Very common on cheapie bikes in the early MTB days (late '80s - early '90s).
