    Excellent Customer Service

    Posted by Mike M on Jan 30th 2020

    When I purchased my Drive Shaft a few years ago it contained only a 15 mm adaptor. I recently purchased a 12 mm thru axle gravel bike and needed an appropriate adaptor. I called Customer Service and they were gracious and willing to send me out a 12 mm replacement adaptor immediately at no cost. Rocky Mounts sets a customer service example I wish other small companies would follow. Bravo.

    12mm shims works like a charm really easy to put on and the bike stays really steady on it
