I have the opportunity to buy a brand new FSA SL-K Light BB30 compact crankset for less than 1/4 of the retail price. It sounds too good to be true but I will pick it up personally so I can check it out before paying.
Anyway, the combination is 46/36 and it's 175mm. I'm currently using a 50/34 combination and 172.5mm. Would the extra crank arm length give me any problems?
Also, if I chose to use the 46%36 combination what would I have to do? I guess move down the front derailleur and shorten the chain? And how would a 46/36 combination impact my riding and pedaling? I have a tendency to ride with a lower cadence than I should...
Or maybe it would be better to swap out the chain rings for some 50/34 Stronglight chain rings or similar?
What's your take on it? The price is great for that crankset but I'm pretty happy with what I have now so I don't want to use to much money on 3. party components...
P.S: One last question... The FSA SL-K Light crankset is BB30 and I have a SuperSix using BB30. Is it as "simple" as remove the old crankset and install the new or are there any other things that should be replaced? Bearings or something like that? I don't think there are any other things included with crankset.
