i hope this helps , i built my 180 from a bike incomplete ,and had the exact same problem , the 180 uses the alpina type fr hub with the speedo drive ect ( larger brakes ) if u shift the rim on the hub the spokes seem to be too short on one side and through the nipples on the other , the 180 forks have a wider axel boss than the alpina , and if using alpina (like i did ) backing plate , i lathed off the boss on it to suit , when it assembled , just seems to be right that way
