Classic & Vintage - Cottered Aluminum Crankarms
Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
I pulled these out the other day. True cottered aluminum crankarms. I bought them a few years ago from another collector. No brand name on them, but they came with these TA rings. Hope to use them on something.
I saw a set of cottered aluminum cranks on eBay last week. This was evidently one short-lived evolutionary dead end. For your own safety, be careful when using them!

TA made their own VERY odd alloy semi-cottered crankset too. Yet another stumbling block along the way. I could never understand the concept of these odd cranks - which even required a unique proprietary spindle and bolt system. I guess this did eliminate the need for bashing down or extracting a tapered cotter with a mallet, but why bother at all after cotterless cranks were already so successful in the marketplace? More photos here, for those interested in quirky French design logic... TA Criterium crankset (http://classicrendezvous.com/France/parts/TA/TA_cotr_crk.htm) :rolleyes:
I think the main feature of the TA version was the adjustability of placement of the arms on the spindle for perfecting the chainline.

I found a set of aluminum TA cranks, didn't buy they though.
Even though now I think that they would be just so funky paired with the campagnolo skiptooth chain ring that they had for track bikes a long time ago.

Snap! I started a thread on these same cranks earlier in the week. http://www.bikeforums.net/showthread.php?t=383206
I had a set kicking round the garage and was curious as to their provenance. Gotta say the alloy finish on the arms and chainwheels is incredibly lustrous - polishes up like SS.
