Is there a responsive off the shelf aluminum frame that can be used SS or geared without an ENO hub or other modification? I have seen some steel ones but was looking for aluminum. Thanks for any direction.

No, they only make steel ss/fg bikes.

That's not what he's asking. Go back and actually read his post.

I see.

Old kleins and TT/tri bikes are both aluminum with horizontal drops and cable stops.

There will always be some kind of modification when switching between SS and geared, or simply refrain from shifting gears.

Also an old virus frame is aluminum with horizontal drops and a RD hanger.

Or get a BB30 modern road frame and get an eccentric BB for chain tension when fixed.

Does it have to be responsive?

Are you talking about something that you can buy new, today, retail?

There are a gang of them... but "geared" means IGH.

Jesus Christ, people. He's asking about aluminum frames with horizontal dropouts and provisions for mounting a rear derailleur, which can be used for either single speed or geared application.

IthaDan is the only one who gets it.

Thanks for the info so far. Let me clarify a little. I have a geared Salsa Campeon that I ride but I'm looking to build a SS to ride some too. I live in central VA where it's pretty hilly. I'm smaller & lightweight so usually I am a good climber. I would like the SS I build to be light and responsive to pedaling input. That's why I am thinking aluminum-carbon is out of my price range as well as custom steel. Are there any aluminum SS dedicated frames that use a 130mm rear wheel, maybe with sliders for tensioning? I don't want to use a tensioner, I did that on my mtb & didn't like it. Again any direction would be appreciated.

Wrong. He said off the shelf. Usually meaning a retail shelf, not the shelf in someone's garage. And he didn't say horizontal; sliders could work.

Like i said earlier look into a BB30 frame (CAAD10?) go with an eccentric bb for tension. I don't think it's going to be easier than that because I don't think there are aluminum frames with replaceable dropouts like a surly troll.

Wait a minute... So you don't need gears? Just get steel. It will be light enough. And more responsive that AL.

What reasonably priced steel frame would you recommend that would be as responsive as an aluminum frame?

There's always this:

Will you define responsive? It means one thing to me, but I read you to be saying that it means stiff or rigid.

I just mean that when you pedal it goes without anything effort wasted. I know this is a subjective matter. My Campeon does this without being an extreme stiff ride so I know it can happen. I have a Mamasita and an El Mariachi for mtn bikes-one Scandium aluminum, one steel (both set up similar) and there is a noticeable difference when you pedal. There is a difference in the ride quality also, steel being smoother, but on the road I don't think the ride is as important as I don't plan on doing centuries on a SS. Hope that helps.

I maybe a little off point but this thread makes me think of this...

Cinelli Mash Histogram (Roadbike)

I'm curious as to how that was accomplished, with regards to dropout spacing in particular.

There are a lot of bikes like this kind of setup, just remember to check the o.l.d. for 130mm and the type of dropouts

The frame is constructed of 4130 double-butted steel tubing.

I didn't know that bike is steel. I want it more now.

With a MASSIVE carbon fork.

I'm totally into it. I don't even know why.

1.5" carbon? oh yes.
