Inertia Racing Technology i50C – MSRP $1599
Inertia Racing Technology is a smaller company with its own way of doing things. They recently brought all of their production and materials to the US so the product is 100-percent made and assembled stateside. As implied by the name, the i50c is a 50mm deep carbon clincher with a standard V shaped rim and width. These wheels are the lightest in the group at 1,520g for the set and feature 20 spokes up front and 24 in the rear. The pair comes with brake pads and skewers and is compatible with Shimano, SRAM and Campagnolo and work with 10 or 11 speed drivetrains.
As the lightest set in the group, these wheels feel fast and responsive. They get up to speed quickly and, for wheels of this depth, the i50c creates the sensation of holding top speed well on the flats and rollers. You’ll notice a bit of loss from the deeper wheels, but they don’t get as pushed around in a crosswind so lighter riders may be better suited with this depth. The full carbon rim eats up road chatter well, but it lacked that extra bit of comfort offered by wide rim wheels. I used these wheels with 23c- and 24c-width tires and the broader tire certainly helps smooth out the road. Braking power is not quite as strong as some other carbon clinchers in the test but is still adequate. Even on some of Boulder’s steepest descents I felt comfortable as long as I planned ahead a bit.
