I'm a little confused. Are you saying that TA Cyclotourist triple chainr ing bolts are a different diameter from double bolts, in addition to being longer? I have both doubles and triples, and had not noticed this. I don't think the diameter of the thread can be different, as the chainrings, with 7.2 mm bolt holes, are the same, whether used with double or triple s etup. Is it just the bolt head then that is different? There were dif ferent styles of rings and bolts over the years. Most rings one sees now have countersunk bolt holes, but some older ones do not. If there are dif ferent bolt head diameters, perhaps it the ones made for countersunk holes versus noncountersunk rather than triple versus double.

Trying to source a couple TA parts.
First off, I would like to find a Pro 5 Vis outer 'cyclotouriste' ring
in the mid to high 40's, 46-48 max. I have a 50t if anyone is interested in a trade. Also have several Pro 3 rings to trade.
Lastly, I am looking for one (1) triple chairing bolt. The older style with TA stamped on the head. I need the version made for a triple and that is 10mm in diameter- not the 12mm diameter one. An example of the 12mm one can be seen in this auction:
The 10mm looks exactly the same, only difference being the diameter of the bolt head.
Thank you.
