Yes, alright, alright... argh... ok - can one put an adapter claw on a track end in order to use a derailler? Can anyone suggest any particular deraillers I could use on a track end? Thank ye all.

OK, I'll bite. What's a "track end?"

a fixed gear end, where the drops are horizontal and face backwards.

I think he means track drop outs.
What about a clamp on derailleur hanger? the
kind ususally found of cheap bikes?

What kind of track frame is it? and
why put on gears/derailleur?

Now that's a twist. Most guys are trying to figure out how to make a frame with vertical dropouts into a fixed gear. I'm going on record to say that I think this is a real bad idea.

I'd anticipate a couple of problems. What are you planning to use for a rear wheel? I'd suspect you are going to have drop out spacing issues. Fixed gears usually have 120mm dropout spacing, road bikes have 130mm. That's almost 1/2" of difference!

As another poster indicated, you could try to use something like a Shimano Tourney derailleur or a bolt-on hanger from a cheap bike, but you'll be sacrificing your entire lifetime's accumulation of coolness points.

In the early 1970s, I ended my brief encounter with fixed-gear by giving my Swedish track bike to the shop manager at Bikecology. Mike took a SunTour claw, turn it around to point backward, and ground the contour to make a reverse-direction stop. He respaced the rear axle, dished the wheel, and installed a 4-speed freewheel (a 5-speed Regina with the outer cog removed). A 5-speed, 120mm road wheel would also have worked quite well in this application.

a) they're track ends... not dropouts... the wheel can't "dropout" of it.

b) i'd like to equip it with gears because I've moved out of Boston where single speeds are just dandy into western Ma where hills are abundant

c) the spacing is already at standard MTB'ish 135mm so that's not a problem

d) As for this notion of "coolness points" -- it is of no concern to me whether someone else thinks this is "cool" or not, I don't want to buy a new frame.

e) thanks.

If money is no option, know a good fabracator/machinest?
