Hi,
A short summary for easier reading:
Bike model: Reid Granite 2.0 (they call it a gravel bike. I use it for all purpose commuting)
Went from a stock Claris FC2450 crank to a 105 crank.
Both are double chain rings.
Stock Claris Bottom bracket octalink stated 68mm.
New 105 crank , new Hollowtech 105 bottom bracket , also 68mm.
Measured bike frame bottom bracket shell, it is 68mm
Now, with the new105 crank and new hollowtech 105 bottom bracket, the crank arms will hit the chainstays,
1) Why does this happen....
2) Can one put spacers with the 105 hollowtech bottom bracket? (I have spacers from previous mtb bbs which can be used) Some road guys said no, the 105 crank arms are not secure if you put spacers.
*if more details are required, do tell, and I hope to be able to provide as much as possible
