TA Cranks
I just re-assembled my TA Specialtes cranks after tearing them down and having at them with the Simichrome. They're going onto my Dawes Super Galaxy that I"ve completely disassembled and am building back up. The Suntour Cyclone derailleurs are in fantastic shape. I'll be installing black cloth tape w/shellac and new gum hoods. I hope the bike fits as good when riding - it's about 59cm.

It's ironic I paid $20 for the bike w/o seatpost/saddle. New CLB and other braided silver cabling from Velo orange, a special 23mm crank puller [aluminum trash that self-destructed], cloth tape, shellac, and other items will run the total up to about $100. I'm looking forward to the 1st generation Cyclone since I've always liked Suntour dérailleurs.
I have several pedal choices. Shimano double sided black SPDs, The MKS like pedals it came with. Shimano 600 track pedals w/straps - triangle shape very similar to the Dura-Ace on my Paramount [$400 NOS - not that I bought them]. Silver color Look style. Another MKS like that are trapazoidal shape - the front is narrower than the rear w/straps.
- current pedals are similar to these

The Velow Orange Cyclotouristes are the same as yours, but they're new. There's only one grade. By black inlay do you mean the sticker on the arms? They cost $4 last time I bought some.
I bought a new 52 ring for my Cyclotouriste and then I rememberd that sold the arms at the bike swap!

With almost the same "TA" stamp? except mine doesnt have the "52" over the "T" and the "made in France" on top, just small on the bottom? also, his stamp is on the 5th leg (clockwise) and mine is on the first leg (clockwise)

BUT... I do believe that someone else in Japan (like "SR" maybe?) did also make some dead ringers for the TA crank arms. Might want to check if the cranks will take a standard 22 mm dust cover. - Boy, wouldn't that be convenient.

I love half-step-plus-granny gearing, and TA did a a good job of supporting this gearing system.

Stronglight also made arms that would take the T.A. rings.
I doubt if any but the T.A. had the recess for placement of the T.A. sticker. Velo Orange has the stickers if you need them, by the way.
The nice thing about the Cyclotouriste crank is that T.A. still makes the rings.
Any Cyclotouriste double can be turned into a triple with the addition of a ring, longer bolts and spacers.

Sugino made the PX crankset which used TA inner bolt attachment and TA BCD for the rings. I have a few of the "TA" Sugino rings; they are nearly identical to TA rings.

Have any of you TA or Sugino crankset owners experienced any problems with the small inner bolt circle which attaches the spider to the crank? These bolts are subject to very high levels of shear, and I read somewhere that they are failure-prone, but I have no firsthand experience with this.

Have any of you TA or Sugino crankset owners experienced any problems with the small inner bolt circle which attaches the spider to the crank? These bolts are subject to very high levels of shear, and I read somewhere that they are failure-prone, but I have no firsthand experience with this.
BUT... the main reason the crank was damaged was that the chainring nuts and bolts had loosened and a couple had eventually fallen out and were lost. Not having correct replacements handy (and I suspect that being young and careless) he had attempted to use 5 simple machine screws and hex-nuts as replacements. These were ill fitting and left a lot of slack in the holes of the arm which then soon "ovalized'. After I had replaced the arm I used the bike with the same set-up for thousands of miles, on the road, and without brakes, which uses more torque than a touring set-up with a derailleur. I never had any problem with damage to the crank. I now have TA or Stronglight versions of this crank arm style in use on 9 different bikes. I love them. I'd feel comfortable bicycle touring around the world using them.
The TA chainring bolt kits do come with "wave washers" which are rather uncommon in the US. These are very thin... well... "wavey" (rather than split) lock washers. So, you really do want to be sure to use these to prevent the cheap looking zinc plated nuts and bolts from loosening. The nuts are a bit longer than the thickness of the crank base and these fit a short distance into the chainring making a snug fit. A simple yet effective joint.
This is one of the oldest bolt circle patterns in all of cycling and Stronglight and later TA had simply adopted this early standard on their alloy cranks. This pattern had been used for many dacades previously on steel cranks from many different manufacturers and there were never issues with sheared off bolts even under the most demanding conditions. Jacques Anquetil had even used a 49D alloy crankset with this bolt pattern as late as 1957... when winning his first Tour de France.
On the Stronglight 49D the "nut" enters the crankarm from the front of the chainring. The TA cranks have a smooth bore all the way through and their nuts enter from behind to rest part way through the chainring bolt holes. ... I see no advantage to one over the other.

OK, I took one of my Sugino caps and tried to pop it onto my crank, it didnt fit, fell right through without touching the threads so Im guessing that makes it a true "TA"!
