This the new beginning of this thread lol
heres a recap
op is seeking advice on how to accurately decided on which spindle length to purchase online for a one piece to sealed bearings bottom bracket conversion.
op has square taper cranksets on hand and a order already placed for American to euro bottom bracket adapters.
op does not have bottom brackets in his possession.
Crankset length are 149mm and 170mm
with plans to take more measurements as requested.
The conversion that will use the 170mm cranks. Will use a shimano Alphine8 IGH. The conversion with 149mm cranks will use a shimano nexus 3 speed IGH. I have both hubs in my possession.
the end plan is to purchase three shimano un300 bottom brackets. For three bikes. Both conversions included.
