I read that the Compact frames were built in Far East, and the adjusters were to take up the bad frame build errors !!!!! So you could get the correct rear wheel aligment..
Dont know how true it was...
The 'new' compact frames are made in china !
To know if you have a Gios which is made in Italy it has 'Made in Europe' on the top of the seat tube.
The adjusters were not made to take up bad frame errors by the way! But for different tyre sizes and block sizes,
You can adjust the chainstay length by about 8mm, Shorter stays make the bike more responsive and quicker,
lengthening the stays makes for a more stable ride.
I've been playing with my adjusters and with them set right back the wheel is still bang in the middle.
After several chats with Marco Gios i've learned alot more about the Italian Gios.
