Hi peeps :D
im getting a new BB online and i came across this guide below:
**"There are two key measurements that you need to know when ordering a bottom bracket.
The first is the width of your the bottom bracket shell on your bike's frame. You can measure that with an ordinary metric ruler but you have to be pretty precise. ** If it's 68 or 73mm, you have an English threaded bottom bracket. If it's 70mm, you have an Italian threaded bottom bracket..."
Im totally stumped as to which measurement to use, could you comment on the picture ive attached and tell me how i measure the shell?
do i measure the red line or the blue line?
Sowwie if this is a nubbins question but i arr very lost atm....!
thanks in advance
