The condor branded cranks do seem to only come in 165 or 170 when I looked at them a couple of weeks ago. However Suginos, Dura Ace etc. do all come in longer lengths as well.
You don't seem to be getting the best service with them Jonah! I am surprised as I have never had anything but good service from them.
Still waiting for my Tempo. Have some wheels (chrome TB14 rims, lush), brakes, seatpost etc. waiting ready. Need to work out a few other bits, including cranks - despite the bike being a general workhorse, it may have a little nod to the NJS thing with Sugino 75 with Zen chainring looking a good option for me.
