Yes, I did search. My crankset is a truvativ elita 48/39. Im using the 39 currently but I don't like it and would rather use the 48. Would it be as simple as switiching the places of them? Is there anyway id be able to just take out the 39 altogether and use short stack bolts? Wouldn't that screw up the chainline though? I was looking at spacers to just replace the 39t but they are all in 20 packs the only ones ive seen in fives go for nearly 10 bucks shipping.
