    Fat/semi fat Surly troll help amigos?

    Ola.
    Ive been toying with the idea of this for some time. Basically I知 about to finish a long, long bike tour and after riding the Great Divide through the USA and then meeting a guy on a fat machine in Ecuador I知 convinced by the big volume/low pressure tyre thing. I知 definitely seeing the advantages of running a tubeless semi fat setup but after a brief foray into looking at new wheels etc. I知 non the wiser. Can anyone point me in the direction of a good resource for all this stuff please as its a bit of a minefield to me. I知 basically wanting to convert my 2017 Troll frame to a 1X11 running 3inch tyres on 50mm tubeless compatible rims. Any recommendations on rims, groupsets or anything else to consider much appreciated. Surly says 3.0 inch max on this frame on a 50mm wheel. And I知 in the UK so we haven稚 fully assimilated this concept as yet.

    If you're largely riding hard surfaces (like the divide) then going to a plus-sized (3" or so) tire is going to give you more comfort at the cost of a bit of efficiency. No free lunch.

    I've ridden the divide but my goal was speed -- and I'd never, ever choose a plus tire for that.

    But for touring the divide a 2.8" or 3" tire sure would be comfy day after day.

    If I were you I'd lean toward something like a 40mm wide rim -- still plenty of air volume using that width, but not nearly as slow as using a 50mm rim on the hard surfaces you've described.

    Bontrager XR2 and Maxxis Chronicle tires are probably closest to what you're after.

    edit: the fact that the Troll is 26" had escaped me. Sorry 'bout that.

    If you're after 3", the Surly Knard and WTB Ranger are about your only options in a touring-ish tire in a 26" size. The 27tpi Knard is hard wearing but doesn't have much for transition knobs and isn't tubeless ready. The Ranger is tubeless compatible and relatively fast, but wears quicker. A WTB scrapper i40 would fit fine.

    You could get a narrow wide chainring for your existing Deore crank, which would probably fit fine in the middle chainring position (might need to move to the outer) or if you wanted a nicer crank, you could run one of Raceface's cinch style or a dedicated 1x boost crank.

    For the rear, SLX cassettes can be found for a reasonable price, SLX or XT derailleur and an XT shifter. (For 26", I'd think 11-42 would be enough. No experience with SRAM.)
