There’s a little update to share with you. My plan was to reinstate the original cottered crank set, until tonight. I had looked at the build thread by Ibbz on his Criterium (very nice) when I purchased mine. I too had toyed with the idea of using a 3 arm alloy crank set but ruled it out. Then on an eBay browse, a cheap 70’s 3 armed Nervar popped up. It got me thinking about using an alloy square taper on the Criterium again. So I had a look on Velobase to see if the Nervar has an ISO taper as I thought it would. To my surprise this model has a JIS taper, which is perfect because the bottom bracket on the bike has a Tange spindle fitted to run the Sugino GT crank set. Then I noticed an offer from the seller, I thought about for 5 minutes, then went for it. A little work will be needed but if the blue in the flutes is a half decent match with the rings on the frame, it might get tidied up and used as is instead of stripping it.
The 3 arm TA crank set does look sleeker than the Nervar, and better quality most likely. However, I think the Nervar has more of the look of the originals, the way the chainrings are fitted to the rear of the arms, rather than flush.

The paint has been stripped off and then everything was given a gentle hand polish. It looks loads better now.
I discovered the spindle is not Tange as I thought, so I now need to find a JIS tapered replacement. It never ends

Thanks Ibbz, just following your lead. Hope you’re well. I’m now thinking I should have gone down the TA route, these Nervar are killing me
they are supposed to have a JIS taper but only pull in on the spindle taper halfway, not enough for me. I can only get a few turns on each nut. I tried them on an ISO tapered spindle too, same result. I think the tapers on the cranks are out of tolerance. They are flat, clean and undamaged but not quite right.Similar threads
