acidfast7,krobinson103: yeah, I suppose I should try to ride the 48T hoping to get used to it and do it despite the cross-chaining, it might be just the cost of getting used to it. After all I can go as low as to 48/18 without cross-chaining, and even 48/21 with a little crossing which is close in term of ratios to the range 38/13 to 38/18 and it is the 38/15 I usually ride the most so I suppose I could be fine.
