All:
I have checked the archives, but could not find a good answer to the following issue.
Yesterday, I snapped my second NR Campy crank arm in three years. This time, the pedal eye "ripped" on a downstroke. (I fell over, but nothing more than road rash--the frame is unscathed). The first time, the arm cracked across the arm about a inch below the eye towards the axle. The cranks were installed at my LBS, and they are very good. So, I wouldn't fault them. I ride 3000-4000 miles per year. Once or twice a week, I ride hard (20-22mph) for 1-2 hour "time trials" but I am no monster. I weigh about 150 lbs. and am about 6 feet one inch tall. Clearly, I am no sprinter. I do climb well and like to get out of the saddle.
Both cranks were from the early 1980's. Are cranks of this vintage too old to be ridden on a daily basis? I really like the "look" of the cranks and would like to keep riding them. After the most recent fall, I am a bit hesitant to go to ebay and look for "lightly used" cranks. Is it best to pay my money and take my chances or is it time to "modernize" the cranks for my everyday ride.
All suggestions welcome.
