okay well im in the market for a reasonably priced, but good quality crankset (arn't we all?) and anyways i came across two that catch my eyes because of their reviews. THe Truvativ Stylo SL and Stylo Team. There is a very small weight difference and color difference but beside that i see no physical difference. Is there really any difference at all in performance here? the SL is cheaper im just wondering why really. Oh and as for a bottom bracket has anybody had expirience with the Truvativ Ti ones>? are they even worth it?
