Just curious ...
I'm starting to shortlist stuff for my next build, which'll be a fully rigid, geared, 29er (sometimes on drops, sometimes on H-bars). Dunno where in the current cycling taxonomy it'd go, but I guess it's maybe just a good ole' fashioned 'mountain bike' (err, of sorts ... 😉 ).
The [i]curious[/i] bit comes with me thinking about using the Surly Enabler fork ... I won't be running a fatbike tyre up-front [yet], but the option to do so [i]might[/i] be useful down the line - an' using a 135mm front end now, would save mucking about later.
Initial build will be something like the Surly 135mm front hub and probably a Crest rim (or similar), but running 2.2 - 2.4's (and the the same rim/tyre on the back).
I can't see any real disadvantages to this, other than [i]maybe[/i] a tiny bit more flex in the wheel from the slightly longer spokes ... but was wondering if anyone else is doing anything similar and might have anything to share.
Equally, feel free to pitch in with any subjective / informed views on the ridiculousness / genius of it all. 😛
Running a single speed rear hub will mean you will have a really good bracing angle a symmetrical wheel. Both of these things will result in a stronger wheel!
Down sides
1. more weight.
2. Can't run a front dyno hub. (not impotant ot many)
3. Can't fit sus fork without building a new front wheel.
Can't think of anything else off the top of my head.
