I just finished building single speed Surly Instigator a few days ago and everything when smoothly except an issue I had with the pedals I purchased. I got a set of Truvativ Holzfeller pedals as I liked the idea that they screw on via a hex wrench through the opposite hole on the crank. Anyhow, there was nothing wrong with the pedals, except that the traction pins they come with are just plain scary! Basically, they are 3M socket head screws at the base narrowing down to a 2mm pin that grips your shoe. According to Truvativ, you can either use their replacement pins or use 3mm x 12mm socket head machine screws. Instead of removing the pin and measuring it myself, I assumed that they where 12mm, so I set out today to find some 3mm x 8mm screws. Figured that 3mm less in length would be perfect. After driving all over town to different hardware stores (3M screws aren't very common), I found what I was looking for and came home. When I put the new screw/pin on it was the about the same length! Turns out what they were calling a direct replacement was actually off by 3mm (3mm by 9mm)!
What's the moral of the story? Don't always assume what your read on the internet is true. Take the time to take the measurements yourself!
