I know what the zip tie is for, but, WHY when you can just take out the spring, it's easier than a zip tie, you dont have to use a new zippa every tip you take your back wheel off, it's looks better and you can still use all 6 gears perfectly well.
Also, the Koxx frame does not have a CNC headtube, it costs too much for them, but the echos are fully CNC'd and cheaper than the XTP's.
