I have a 2000 Cannondale R3000 with about 20k-25k miles on it. I'm wondering whether to replace the bars and/or stem as a premptive measure against failure. I've done about 25 races on the bike, couple of crashes but no visible damage to the bars. I've put aero extensions on a few times for time trials. I plan on getting a new bike next year but will keep this one as a backup and early season bike.
