    5 of 5 Great Service August 10, 2020
    Reviewer: Richard Jaeger from Hazlet, NJ United States  
    I phoned MM on a 7/31/2020 and left a message, within 30 min got a return call from George, spoke to him about my needs and questions. He explained what I should use to build my bike. I ordered the Sprocket, Hib Adapter and chain tensioner.  I received a e mail the next day advising that the order was received and items shipped. they arrived on 8/6/2020  Quality items and machine made CNC . No stamped or cheap made shit from China. Made in the USA.  You have a customer for life.

    5 of 5 Perfect fit June 16, 2020
    Reviewer: Joshua Aguilar from Wyoming, MI United States  
    The custom hub adapter fit my shimano hub perfectly. My calipers read 1.129 for my hub diameter and the conversion reducer I ordered was 1.125. The conversion reducer combined with the standard 1.5” hub adapter is definitely the best solution to weird hub diameter problems. The sprocket was okay. Perfect fit with the adapter but I would like it to be drilled out/slotted more.
