Interestingly, the GRX rim has the same dimensions as the Terra CL rim: 32 mm deep, 30 mm wide (external), 25 mm wide (internal). However, the GRX wheelset weighs 1,484 g, and only has 18 points of engagement.

Is a $300 savings worth an almost extra 100 g and only half the engagement points? I suppose that is for each rider to decide.
