GT Team Avalanche BB width for 1x commuter

[27motorhead]

My 1990 Team Avalanche has a 68mm shell and pics to prove it... foreshortening and camera angle don't help show exact width, but it's 68mm NOT 73mm...



Seems like GT are playing with our minds @PhillB !!!

Regarding what BB width will entirely depend on your choice of chainset.

Wow... I must apologise for giving erroneous info. I've measured my 1990 TA and it is indeed 68mm...I actually measured it 5 times, that's how 'sure' I was it was 73mm.

My 1991 Team Avalanche is 73mm, measured that too..

Sorry!
