I don't have a set to measure, but I seem to recall that they were ROAD, not
Pista crank arms that had the shelf for the inner ring machined off. The
difference will be in the distance between the face of ring and the arm, the road
crank has more by about 2 to 3mms. I used to have a pair of 175s in silver,
that I bought as a sample at a BDS Expo in Las Vegas, they disappeared along with
my Ron Cooper track bike during the Rodney King riots.
BTW, I got a great deal of grief from a BMX racer (now grown up) who swore
that all the racers used 3/32 chainrings. He was selling a bunch of stuff on
ebay, and I questioned his description of a 3/32 ring as "BMX". I seem to recall
his name is Ed Porter and he's a bit of a jerk.
