Good Gear Drive Product came well packaged and in a timely manner. Product is fairly priced, it came with easy to follo directions. I have had several gear drives, while this is noisy, it is far less than some of the others I have had. However the others were almost 2 1/2 times more expensive. So if you are looking for noisy, it’s the one, if you are looking for real noisy, well. I will say that it is well worth the price, great quality. Thank you for your quality and service.
Noisy and a Lot of Back Lash Just don’t! It is noisy and offers no more precise drive for the came than a chain. Actually the back lash is bad.
WORKS EXACTLY AS ADVERTISED Well I was after that gear whine and the Proform Gear Drive 66917C gave me exactly what I wanted. Not very noticeable on the freeway, but the drive has quite a whine going through the gears (smiles). Nice product, quality seems good, and the price was right!
