It took 10 minutes for the first meaningful chance and Diego could have done better when he put his shot wide of the post for the hosts.
It was turning into an end-to-end encounter, with Antoine Devaux putting a header wide for Reims before Granddi Ngoyi shot wide for Troyes.
Reims were ahead just before the half-hour mark through an Aissa Mandi header and they held their lead to the break despite Mounir Obbadi's best efforts with a blocked shot.
Troyes came out the stronger side in the second half and had two chances before 60 minutes to level, Ngoyi shooting wide and then Mohamed Yattara missing with a header.
However, Troyes were level on 63 minutes, Bachir Camus scoring after meeting a corner.
Despite a few half-chances at both ends, neither side was able to snatch a winner and the points were shared.
