Whilst the weight saving is not great, in these days of marginal gains every little counts and this could provide the aged veteran with just that little extra edge.
Having said that I can recall back in the late 1970's that a rider from the Folkestone and District Wheelers who lost his teeth on the climb up from Chilham to Ashford carried on regardless and then enlisted the help of his club mates after the event to return to the scene of his loss to effect their successful recovery.
So remember my motto "If in doubt, take them out".
