The I9 Carbon S wheels are stiff but not harsh. I am a heavier rider at 250lbs these wheels hold the line without punishing feedback. I am very impressed with the balance they were able to build in these wheels. The hub engagement on the Hydra hub is also great on technical climbs when ratcheting the pedals.
These wheels are light, strong and have the Hydra hubs which engage immediately on any incline. They look sweet and fit wider tires.
