hi , i doubt if i will ever sell my glx either , i bought it in the mid 90/s it has an interesting seat tube badge and i will launch a close up of it one day . It cost me £ 250 fr+forks
I believe there was a cross over from the billato factory in Italy from the 'z' team tsx's . perhaps a gan lemond
could be viewed as a tsx with different lugs and tubing or in some cases the same lugs as the tsx with a non rounded fork crown on some of these .and a GLx as opposed to greg's inverted triangle/with an 'L' IN the midddle
the handling is very good,that is , as good as the end of your crank arms will allow.. chris boardman rode one of these..i believe in 93/94 .
