I have 27 x 1 1/4 Super Champion rims on my touring bike and 27 x 1 1/4 Mavic rims on my smoothie I ride on park trails. Both are excellent rims. I also have a set of wheels with Wienmann rims that don't have a hook profile like the Super Champions or Mavics and won't allow tires pressures of more than 80 psi without blowing tires off of rim but they're fine for low pressure touring tires.
