I have the profile madera cranks with a 5 7/5" cro mo profile spindle. I found a fsa titanium really cheap but it is listed as only 5 1/2 inches long. I am running the 5 3/4 inch profile spindle now. Will I run into issues losing a 1/4 inch? Any problems with the splines and tolerances between profile and fsa? I know the site says it works just looking for personal experience.
