Photo shows the brackets used with training wheels. Thin (usually 17mm) inside nuts hold the wheel in the drops. Brackets have a tab engaging the slot to keep them from spinning. Training wheel arm would (if they were present) have a channel cross section, fitting over the brackets. Outside nuts (usually 15mm) hold the training wheel arms tight against the brackets.
If training wheels are removed I like to use the standard 15mm nuts to hold the axle in the drops and return to the customer the rest, zip tied to the training wheels for future use. Andy.
