Campy cranks too flexy for a larger rider (200lbs)?tmac13

As I ponder upgrading to Campy, i have heard that the cranks and bb tend to be not as stiff as Shimano (or FSA) for larger riders. I just started racing Masters 35+ last year and will continue this year. Any experiences? Thanks.

with my Centaur crankset. I weigh in at 195-210 depending on the time of year. I don't race my road bike however and tend to spin the pedals as much as I can when climbing. I think Campy is worth a try at least. You can always get the Chorus or Record carbon cranks.

I have ridden both Record 10 and DurAace 9. At 212 lbs. and after many miles, I have not found a difference in crank performance between the two.
Go for it!!

On the better cranks from C or S, frame flex is far in excess of any crank flex. While one crank/BB combination DOES flex more than another, the total amount from these components is small compared to most frames.

Your frame will flex long before you flex a Campy BB. Have you ever held one in your hand? If so, do you really think you could make that little spindle flex? Not likely.

This tests are purely academic and were performed in a "lab" using such advanced testing equipement as a vice to hold one end of a crank arm while force is applied to the opposite end. Then they measure the flex in fractions of a millimeter. I have seen a lot of bikes but I've never seen one with a BB as stiff as a table mounted vice. So IMO the test really don't mean much in the real world.

BTW-- I have Campy Record aluminum cranks, DA 9 cranks and FSA carbon cranks and I will soon have 2004 Campy carbon cranks and there really is no difference in the stiffness of either crankset/BB.
