This is my first post. Please forgive my ignorance. I just got a bike and had a hard crash on Saturday because of a pedal strike caused by leaning to far in a corner. My current crank set is a FSA Vero, 130BCD, 172.5mm. I am considering changing to a Sugino RD Crankset, 130BCD, 165mm so I won't pedal strike going around corners. Here are my questions...
Will I need to change my bottom bracket when I go to a Sugino RD crankset? The current BB is 68 X 107mm and the Sugino RD crankset keeps refering to a 68 X 103mm. Sugino makes a BB that is 68 X 103mm.
Another question: Will this affect my chainline? My current chainline is 43.5mm but the Sugino RD information says to use a 68 X 103mm for a 45mm chainline.
I'm pretty confused. I basically want to change my crankset but not my bottom bracket. Can I do this?
You'd be moving the chainline 5 cm if you didn't get a new bottom bracket. I'd personally just buy the RDs and a generic Shimano 103mm BB for $20. Then sell the whole Vero kit on craigslist or something.
