I still run two sets of these and had a third mint set on my ProClass a few years back.
Brilliant cranks but i've only paid £125 tops for a mint set and my rider set pnly cost me £80 as a guide. All collected prices.
I think they came out in late '88 so only just 80's and more towards the mid not old, but half the cost of 401's but with the looks for the price of twinchers..... No brainer to me.
Get em bought Tel and ride the fookas.
