    Differences between Shimano SLX hubs M665, M675, M678

    HI,

    I had narrowed down my search for a new hub to a Shimano SLX M665 hub, but came across the M675 and the M678.

    Can anyone note the basic rideable differences and technical diffs in the hubs, and even share quality issues if known.

    I do know that the M665 has 32 POE and that the M675 and the M665 are supposed to have 10 mm threaded axles.

    Thanks

    So Cal Rod

    The 665 model is the standard quick release. The others are the 15 and 20mm axles. I can't say much about any quality issues between the hubs, but the axles will provide a digger and stronger front end. If you are wanting to purchase the 665 slx i have a set of these I'm trying to sell on Craig's list as well as the center lock rotors. Everything is brand new and still in the box.

    15 (678) and 20mm (667) axles are front hubs only.

    The 665 and 675 rear hubs are both 10mm QR
    Front 675 is 9mm QR

    Okay, this helps a lot!

    What is the difference between the M665 and M675 rear hubs? Shiggy and Vudoo seem to have different info for these two hubs. Are they both 10mm or is one 10 and the other 12? The diffs with the other hubs have been answered for me.

    Sorry, just looking for clarification.

    thanks again.

    VuDoo missed that you were asking about the rear hubs. My info is correct.

    The 665 and 675 the same design and part numbers. The 675 is just part of the 10-sp group.

    I'm also considering some SLX hubs for a build I'm doing this winter and am debating between the M665's and the M675's. I can get the M665's for a cheaper price because they are on closeout, should I go for them? Aren't they basically the same thing as the newer models? I'll be running 10 speed, which will be fine on either hub, right?

    Well, I think this still applies:

    Yes you will be able to run a 10sp cassette on either hub.

    Thanks 006_007, major brain fart. Like when you add 2+2 in your head and still feel the need to double check with a calculator to make sure it is 4.

    Hey VuDoo11, do you still have those SLX hubs and rotors you mentioned awhile back?
