could someone let me know what a cathedral bit is? see story below. I needed a riding horse for over the winter break, so have borrowed a friends horse. the mare has been really well trained in western type riding & has been doing well considering she has been in the paddock band for the last 7 years. she has been well looked after, hard feeds, teeth done, wormed but unfit so i have started her very slowly & as she gains muscles, will try to do more with her. the only problem i forsee is that i have been told she used to be ridden in a "cathedral" bit, i don't know what this is but sounds bad. i have put her into a nice plain snaffle & at the moment she is taking it OK. she gets a little nervous, is expecting to be told off, so i am taking her for lots of walks & only very little jogging. loping on the lunge only (not because she is uncontrollable, but it seems to make her very upset when ridden).
