Mountain vs Road hub?

Anyone knows the difference between hubs labeled as Mountain vs Road hubs?

I'm looking at buying a DT Swiss 350 hub, and there are 2 options.
  • 28H 142x12mm Road,
  • 28H 142x12mm Mountain.
What would be the difference (if any)?

Are they both disc?

Otherwise, it beats me if the axle types and hub widths are the same.

Are they different part numbers, or just the same part listed under different categories?

Yes, both centerlock, both 11sp. Beats me!

I wonder if it's a weight thing, i.e. mountain uses heavier/sturdier bearings or something like that.

Take a look at the DT Swiss page for the 350 hubs: https://www.dtswiss.com/en/products/...s/350-classic/

Look at the rear hubs. There are three variants of the 12x142 rear hub with centerlock. The difference between the three is in the free-hub body. One is the SRAM XD driver hub, one is 11 sp Shimano "Road", the other the Shimano-style non-road 11 speed. I think the different between the latter two is that Shimano road cassettes are a tad wider then the MTB 11 speed, so the freehub body needs to also be a tad wider.

However, I do not see DT Swiss calling the hubs themselves "Road" or "MTB". that is likely the sellers description. You just need to know which freehub these have.

Yeah, I believe you are right.

Seller replied that "mountain" is for Shimano HG MTB 9/10/11-speed SRAM 9/10-speed and "Road" is Shimano/SRAM 11-speed (road).

You got your DT swiss feedback..

older shimano... road was less sealed, so lower friction from seal drag, than MTB..

Yep, road 11sp has a wider freehub body. MTB 11sp cogs are set inboard a bit -- this is easy to do with a 42t big cog, even with the slight angle of drive side spokes.

Back in the old days of seven speed freewheels, the only difference was black vs. silver.
