Alternative to TA Crank

As I understand it, the TA cranks are no longer made. Assuming I don't want a triple, but want more low end gearing flexibility than a 110 compact double, what other options exist?

Thanks

If you can live with a 44 or 46t "big" ring, a 94mm bcd ("compact" mtb) crank will go down to 30t on the "middle" (inside on a double) ring. Velo Orange has TA and Sugino PX crankarms, both of which take the TA Cyclotouriste rings. And Electra has a TA-clone crankset on their new Ticino bikes, and claims that they'll be selling the cranks separately.

TA Cranks are made.

This is what I run... the 94bcd double Carmina. 30/46 to 34/50 with rings in between.

Easy. White Industries.

I've seen them in person. They are beautiful and though it may not look it, those chain rings are very stiff. In my opinion, it's one of the nicest cranks available, and the quality is that or better than Shimano, etc.

Only available as a 50/39. Which seems really odd considering the bikes it comes stock on. I think they made an error. It ought to be a 46/30 with the whole "retro cyclo-touring" vibe they seem to be trying for.

There's a T.A. triple on Ebay right now. Eighty bucks and change with 14 hours to go. There's also a rough looking black T.A. double with three days left, less than ten dollars at the moment. And I just bought a pair with a single ring from Ebay a few hours ago, to go along with the new pair I bought from Velo-Orange last year.

So I don't yet see a need for T.A. alternatives.

Thanks. I've got them on the watch list. However, it does make me wonder, if we are scrounging for parts on eBay, then maybe it is time to look for alternatives.

There have got to be dozens of mtb cranksets with mtb gearing or trekking gearing (something like 48, 36, 26) that would work.

Nah. The only reason I bought from Ebay was to avoid the $300+ cost of a new one. Of course, if you'd rather have some gigantic CNCd mountain bike cranks...

Interesting. That 30-45 is just about perfection in my book. That is an ugly crankset, though!

I was thinking the exact same thing...maybe if you powder coated it all black...or had it polished...

It's carbon. Powder coat would melt it (I think) and polishing would be, well, bad. I think that's the kind of ugly that's permanent.

Over on the road forum they're probably having orgasms...

I think you mean MTB Forums, as it is a MTB specific double... but I'd use it if it weren't so fugly and you stole my TA Carmina from me...

The Surly Mr. Whirly is another interesting option. I might be putting one on my SS / FG bikepacking rig...

I picked up one of these: https://www.velobase.com/ViewSingleCo...3-02197cb84b54 for ~$100 on ebay.

Running a 45/28 is perfection for this area. Anything in the valley is the 45, the 28 gets used in the Berkshires.

There are quite a few MTB double cranksets coming out now, including the SRAM XX, which offer chinring combinations which could be quite useful on the road. Unfortunately, they all have the wrong chainline when using a road rear hub and an unnecessarly wide Q-factor to clear MTB chainstays. Since they have integrated BB's, these things are not adjustable.

I mount 28 and 46 tooth chainrings on the inner and middle positions of a regular triple road crankset, and I'm pretty happy with this setup overall.

Just don't wear out your chainrings. They're almost as common as hens' teeth.

Just picked up a Surly Mr. Whirly for my new MTB build. Initially as a SS / FG, but as it is a 58/94 bcd my TA Carmina rings will work, and I can run it as a MTB double or triple if / when I want to add gears.

Its not pretty... but it is functional.
I'm not sold on the outboard bearings... and it does step up the Q a bit... but we'll see how it shakes out.

There's a few on Ebay and there's a guy making custom chainrings for SS's that would work.

There was a limited 60'th anniversary edition of the Pro 5 Vis cranks made a few years ago. I could be wrong but seem to recall reading that these may had been CNC'd rather than cold forged as the old molds were worn out. But I'm quite sure they were a bit different in that they had a larger gap between the arm and spindle so that they are easier to set up with modern front dérailleurs. More here:
https://velo-orange.blogspot.com/2007...nks-redux.html
https://velo-orange.blogspot.com/2007...-are-here.html
Could be that Specialités TA now decided to stock them as they are listed on their site:
https://www.specialites-ta.com/produits/trans_gb.htm
Both the cranks and rings can be found in various web shops:
https://www.sheldonbrown.com/harris/french-cranks.html
https://www.renehersebicycles.com/index.htm
https://www.velo-orange.com/cranksets.html
https://www.bikespecialties.com/site/parts2.html
VO report that they are in final negotiations for their own cold forged 50.4bcd cranks witch may be worth waiting for:
https://velo-orange.blogspot.com/2009...in-taiwan.html
TA are superior to other modern cranks in so many way's and parts are still available so why not take the plunge and get the crank set of your dreams?!

I'm considering the 50.4 bcd Sugino PX crankarms https://www.velo-orange.com/supxcr.html , but I can't find a source for the TA Cyclotouriste rings.

Does anyone have a link?
