    Upgrade from 303 to 404 rim worth it?

    The races I do dont have a lot of climbing and i also do a lot of crits. i currently have 303 rims (the new wider ones) with chris king r45 hubs. i was thinking of getting some new 404 rims (with the new firecrest profile) for more aero benefit.

    is it worth the upgrade or will i even notice the change?

    I may be looking for some 303 tubulars for climbing if you decide on the 404s.

    Tough call as the 303s are good for crits. If you are real strong then you may benefit from the 404s on break aways and solo efforts. Do you do any TT events?

    They are both very aerodynamic designs so any differences will be small.
