    MKS chain tensioner installation

    This is probably a stupid question, but with MKS chain tensioners is part that goes around the axle supposed to be on the inside or the outside of the dropouts. Thanks.

    wrong. inside. keirin frames are spaced to have them on the inside. you can run them on the outside if your frame does not fit them, but its always al ittle sketchy to tighten the nuts down on anything other than the drop outs. that said, i've done it in the past, and im not dead. but they are intended to go on the inside.

    Yes, 128 is correct.

    Inside. Otherwise your track nuts are not grabbing the frame.

    that means i would have to reduce my cone nuts by 1.5mm to make them work inside. i just ordered a pair, i never knew they go on the inside.

    I seriously wouldn't worry about it - especially with a steel frame.

    I think running them on the outside if you have to isn't exactly disaster. Just look at the Surly Tuggnut - only mounts on the outside, plenty of people use them without issue. I wouldn't bend a frame if it isn't spaced to fit them on the inside - I'd just run them outside and let the frame be.

    +1 it is a little stretch but they are good tugs and my frame doesn't mind

    Have you ever pulled a rear wheel? If not, you probably don't ride hard enough for the positioning of your chain tensioner to matter. If you have, then put them on the inside.

    The other thing is that when placed inside the stay-ends, the tracknuts lock down without moving the hub. When they're on the outside (directly under the track nuts), they tend on some frames to cause the hubs to "walk" slightly while you tighten them. It gets quite frustrating when you can't tighten up your wheel where you want it.

    I just picked up a set of the larger ones for aluminum frames. They won't fit inside the drops on my cannondale without spreading them some. I'm a little sketched out about that, but I'm also worried about running them on the outside of the drops. Any ideas?

    If you have that means you aren't tightening your nuts down enough or that there was a lot of grease or oily crap between the nut and the dropout.

    i run them inside on my keirin frame and outside
    on my soma frame. yes, if they are inside, then
    the nut is not directly gripping the track ends, but
    the knurled nut on the inside is gripping the track
    ends. so either way only one nut which is attached
    the axle is gripping the track ends.
