tandem rollers

A quick learner says:
measurements are so close but neither has the angle at the wheel like the original but I'm not sure if that matters. Can you tell me if your 81-138 or 81-030 would be the closest replacement, please?

Hello,

The two rollers you've pointed out, as well as the 81-095 roller, are possible replacements but the determining factor will be comparing the dimensions to your original roller. Unfortunately, we can't get accurate dimensions from photos but pay close attention to the width and thickness of the housing, as well as the diameter or the wheel to choose between the three. Thanks for posting!
