I have a gravel race coming up and I am having difficulties choosing a tire. I am currently running Gravelking SK TLC 700x38C tires and zipp 303 FC wheels.
I know this question may be similar to other posts but it is specific to my situation.
This race is about 40/60 road to gravel. The beginning of the race has an hour long road climb, and then it turns into mostly well groomed gravel.
I purchased some Continental Terra Speed 700x35c because of the rolling resistance and weight benefits and the course layout. However, when I weighed the tires, they arent as light as advertised on BRR, they are updated for E bikes and so are a little heavier. Around 420 grams a piece, so about the same or a little more than the GKs.
Should I install them or just return them and continue with the GKs? I have no problem with the GKs so far and have raced them twice. They do well, but I was thinking of maximizing my advantage on this climb with rolling resistance and weight, and it seems my only benefit now is rolling resistance.
Am I overthinking this? Thoughts? I do have the potential to win the open category for this distance.
