At least with the Sturmey drum brake front hubs, tire change issues are trivial – it’s very easy to connect and disconnect the necessary bits.
I have a Sturmey dynamo/drum combination on an old Fuji Sundance ’80s mountain bike I built up to be a rain and snow bike (hence the drums). It’s quite heavy, but otherwise works like a charm. I have not taxed its braking capabilities, though, and based on the closed design I would imagine long descents could generate an awful lot of heat inside the hub.

Great to hear, Shoji! I'll take all the no brainers I can get! Grin. Thanks. Though the Great Divide is mostly dirt roads not single track, though it certainly has some jouncy section that I've ridden.

Drum and disc brakes put a lot of stress at the hub area. It's more complicated to remove a wheel for tire changes, since the reaction arm has to-be removed. (This may or may not be a problem for your situation.) As for dynamo front wheel-- if you'll be riding in twilight and darkness, it's a no-brainer. (Grin!) It could even be useful to you for the ability to charge electronic devices. Some dynamo lights have a USB port for such purpose. Modern dynamos are robust-- great divide riders use 'em, so I think it'll work for you. --shoji On Thursday, April 17, 2014 9:57:16 AM UTC-4, Deacon Patrick wrote: At some point in the future I will likely need to beef up my front rim to an Atlas to match my rear rim. At such point replacing the front hub with a dynamo/drum brake combo hub is something I am toying with, especially as I’ve found more area dirt roads to ride and nighttime rides would open up some things. My questions are as follows: Drum brakes: — Why are drum brakes not used much? — How practical are they for rugged, steep single track? — It seems they would address the snow/mud/muck loss of braking issues I sometimes experience. Is this true? — Does my frame need anything special, or will they simply go on? Dynamo: — How hearty are they (and the accompanying lights) on rugged single track? Will they hold up or be fussy? Thanks!
