Thanks for sharing your experience. I am familiar with the neoprene thumb braces. The one I have wouldn't really work on a ride either. I almost need to design my own brace to support the area just right. My thumb joints do feel "unstable". Surgery is not an option (last case scenario ...). Here I thought when I increased my mileage, my knees would be the problem. I never thought my "thumbs" would act up.
