I machined some Turbine cranks down to 150.5 over the weekend. Haven't ridden them yet as I am still waiting on some of the parts for the exchange. They turned out nice though and I added a curved chamfer on both the front and back to hopefully skip off the rocks better!
Great thread everyone! I have a found a used set of 175 Aeffect Rs locally which I could machine myself down to 155mm. My A70 has 170 Aeffects on it now. Are Aeffect spindles removable or permanently attached to one crank? If they are removable It seems like I could just use my original...
