    MKS Chain tensioner for 8mm (110) dropouts?

    Hello all,
    I just acquired mks njs chain tensioners to find out that they don't fit my frame! They are the version with the hexnut sticking out. see link:

    I know that mks makes different versions of the chain tensioners for aluminum and steel frames, but do they make any designed for 8mm axle sized dropouts?
    P.S.
    if anyone wants them PM me and I will let them go at a FAIRLY discounted price since they've been opened but not used. They are brand new...

    I'd be also interested in finding out who makes chaintugs for 110mm rear forks as I also made the mistake of buying the MKSes thinking they would fit. Ended up putting in my other bike so no harm done.

    I think those should exist since lot of Japanese Keirin bikes have those narrower forks, right?

    Stupid me. After posting above I started thinking and remembered that I actually had a pair of real old school styled and bit narrower chain tensioners in my parts box which I'd bough from a local mad hoarder dude but never tried them on my keirin frame and hey, they fit nicely!

    I think I can get more of these from the same guy if someone needs them? Just PM me.

    Hello!! I'M Tomity live in Tokyo Japan
    I'm professional Keirin rider from racing 26 years now

    MKS makes only MKS Deluxe Chain Adjuster(NJS) for 120mm,not makes for 110mm
    If you use 110mm(8mm slot drop outs) frame for chain tensioners,you have to use old school styled one

    Tomity.

    arigatou gozaimas hita! Tomity-san... I still used the mks tensioners that I had and improvised with a drill bit and some filing. It took a while, but they work! you can see my bike here:

    I have been trying to find some as well, I did some searching and they are "Banjo-Style Chain Tensioners". They seem to be available online for <$1 to >$6...good luck!

    I did not want to start a new thread and this seemed the best place to ask......so, i bought some of the njs chain tensioners online, cheap, before i had the time to do the proper research. i was wondering if someone might be able to give me the dimensions of the axle, dropouts, etc. on an njs track frame. what I am most concerned with is the thickness of the plate used on the dropouts. thank you, in advance for the help.
