Smooth rotating and easy to install crankset
Replaced stock FSA 19MM 46t/30t Canondale Topstone 1 crank. Works great, so much smoother than stock crank and allows for overall faster topdown speed. Installed myself by replacing FSA BB with SM-BBR60 since FSA BB is not compatible with this crank. Some force with a rubber mallet was required to get crank fitted into new BBR60 BB. A 3/8 torque wrench with support for 40-60Nm is also required to properly torque BB. Non-drive side crank arm is easy to install, just set preload then toque crank arm screws between 12-14Nm (alternating). Well worth the time and money for a crankset upgrade from stock.
Metal shavings on the drivetrain
I have install this crankset on my Topstone 1 that had around 150 miles. So it's a pretty new bike (cassette, chain and derailleur). But after one ride I've noticed metal shavings on my chain, cassette and front chainrings. Before installation I've noticed that chainrings on a new crankset are not smooth (have burrs). Not sure if I got a "lemon" or is it a norm but I didn't see this on any my bikes before... (ibis that has shimano drivetrain and fsa crankset that Topstone came with didn't have this issue).
Awesome crank!
Awesome crank! So happy I upgraded after the OEM crank wore out on my gravel bike.
