To use the ZPIDER, it must fit in the bottom bracket (BB) of your bike. If your BB doesn’t have the measurements required for the ZPIDER, you may need spacers, bottom bracket (BB) or both.
The ZPIDER’s spindle goes inside your bike’s BB as shown.
The ZPIDER’s spindle is 30 mm in diameter. If your BB has another diameter, you will have to change the BB.
The width (or length if you want) of the spindle can be adapted to a shorter BB using spacers.
Start by removing the crank set and any adapters/spacers you have installed – but leave the BB/bearings installed.
The most obvious difference between BB types is the location of the bearings – they can be outside or inside like in the pictures below.
If the width is more than 86.5mm you are out of luck (and you are most likely on a Trek bike). The ZPIDER (and any other BB386EVO) crank will unfortunately not fit your bike.
If the width is around 86.5mm, you need to check the clearance at the bottom bracket. A few frames are too beefy in the bearing area to fit the ZPIDER (generation 1). This seems to only be an issue with carbon frames for press-fit bearings. The ZPIDER has an opening of 49.5 mm in diameter as illustrated by the cross section view below. Please note that the bottom bracket will be seated 7 mm into the ZPIDER:
Therefore the frame should not exceed 49 mm:
If this is ok, you are good to go. No additional parts should be needed. Unless you want to get a new BB.
Pretty good, you should just need spacers.
You need a new BB.
