Yes it's stiff, it shifts effortlessly, it's beautiful, it's light, and it works. No carbon silliness, no wonky chainring shapes, just a simple and elegant crankset. Sure, it's not the lightest option out there... but will you really notice? Will it make a difference? When paired with the Ultegra BB and the Ultegra chain, this thing is unstoppable. As an added plus, when properly lubed, it runs completely silent. As an example of this things strength, I weigh a little under 180 lbs. and I can't get this thing to flex for the life of me... even if I'm standing on it, stomping it up a hill, or sprinting with all my might. Try it, you won't be disappointed. Aside from wheels, an Ultegra crankset is the most beneficial upgrade you can make to your road machine.
