Actually narrower than modern road rims. I've got a NOS set of mavic 220 rims, sadly not rainbow anodized, and they are narrow enough to fit between the hooks of my daughter's Mavic CXP pro carbon rims. I remember running 26x1.95 panaracer fire XC pros on sets of those rims. Another good one is the velocity dyad which used to be the aerohead and is 18.6mm internal and is no longer considered a MTB rim but a touring and road rim but I would fit them with 26x2.1 tires BITD and today is probably a bit narrow for a road rim. All my recent road wheelsets are 19mm internal between the Mavic CXP Pro, Velocity Aileron, and even the Pub rims I built into her track rims.
