Triplizer rings

Triplizer rings used to be pretty common. But you (that is, I) never see them anymore. Does anyone still make them? If not, why not?

I made one out of an old freewheel cog. I think it's working now. This cranks has a small BCD. I'd like to take a closer look at a real one. It seems like a good idea. I looked them up a couple of years ago and they were available but I don't remember where. Might have been Ebay.

They have probably fallen out of favor with the rise of "compact road" gearing and/or two-piece cranks which prevent any adjustment of bottom bracket width to accommodate the third chainring.

I agree with ^. Compact gearing is more common since modern cassettes have a final drive as low as 10 or 11.
You no longer need a 52 up front and a wide double can give a lot of range these days.
I had a mavic triplizer and sold it to another BFer, very nice but I never actually used it when it was installed.

It's just too bad ole PW is such a "Cranky Yankee" and his prices are so high. I've never caught him in a good mood. He's about the only person, when I checked a few years ago, that sells the TA rings here in the USA.

Think about it for a moment. If you wanted to turn your 144 BCD crankset into a triple with full TA rings from PW.

42 Tooth Triplizer= $96
50-52 Tooth Outer Ring= $88-102
30 Tooth Granny= $48

Total would be $222-244 just for the chainrings!

By being patient on ebay I was able to build this Super Record for approximately $120 in TA chainrings.

See Peter White link. That's where I got my last one. By the way, get the 42 tripilizer, use your existing outer and pick up a cheap inner on ebay...

I don't know if he's cranky... always filled my orders. BTW, not sure anyone else still has them.

He is located not more than 25 miles over a few high hills from me. Every time I called to arrange a visit, throw some work his way, and possibly buy some of his stock, he acted as if he didn't want to be bothered. After the third try, I decided it was not worth my effort.

It's a shame, because he does carry some very nice products, and the drive is easy from where I live.

Yes, he's definitely a world-class curmudgeon.

That does come across on his website. It's kept me from buying from him. If there was any problems I don't see reconciliation being an easy process. Apparently he makes enough money to not bother.

Bob at Elliot Bay in Seattle will drill out a Campy crank arm to "triple-ize" it.

See his photos here: http://www.flickr.com/photos/8379107...7622574585267/

I'm sending a crank off to him tomorrow.

PastorBob, as always, that is a fabulous bike. That TA adapter is nice, but it's $96. I'll do the $40 drill job and be happy!

Cheers!

That is a perfect set of ratios, Reverend! I would love to team that ringset w/ a 14-15-16-18-20-23 cogset, for a 1.5-step plus granny without the usual gap at the top. The TA rings look great on the Record crank.

Shimano had the Dura Ace 7703, 9 speed triple crank (53-39-30) with a 30 triperlizer. The granny was attached to a special 39 ring with tabs in it to mount the 30. The 39 was a D-39 versus the standard B-39 (7000 double 53-39). I have one on my Trek 5500.
