Cannondale's attention to detail on the Topstone is excellent, and they've made some really interesting design choices to stand out in an increasingly-crowded category. Apparently they've succeeded -- the Topstone 105 has been the third most popular bike on all of 99 Spokes this year.

Exceptional ride quality front and rear, well-tuned front suspension fork, nimble handling.
Lots of Cannondale quirkiness, heavy.

Rather than singling out one area of expertise, the Cannondale Topstone has the ability to adapt to any situation - trails, gravel and pavement dashing included
Overall speed and all-round terrain ability
Wheels could be of better stock
Not tubeless from factory

A fun off-road machine that ticks all the gravel riding boxes, but the low ratios slow progress on tarmac
Quality off road spec and handling
A bit weighty
