If you have a 30mm BB you only need spacers. Turn the bike upside down and measure the width of the frame.
Find the right adapter in the table below. If the width is more than 86.5mm the ZPIDER will unfortunately not fit the frame.
|Frame Width||Spacer Needed||Optional BB|
|68mm||#10||#3 #4 #7 #8|
There is no strict requirement to change the BB, but in case you want to do it while you have your fingers dirty anyway, the optional and recommended BB’s are on the table as well.
All the spacers (and BB’s) are in the webshop – just remember the right # numbers.
