    Default N+1: How Much Tire Space to Plan For?

    I'm thinking about the next bike. It's been six years so I have the itch. I'm looking to do something in 650B for roads & trails but unsure how much tire I should plan for. My Seven was modified a few years ago to accommodate a fatter tire and fenders but the Babyshoes (42) are the outer limit of what will fit between the chain stays. I know, for example, the WTB Byways (47) definitely don't fit!

    My Seven is equipped with a wonderful porteur rack, bag and fenders and serves me as commuter, rando bike. I'd like something that I can throw FAT knobby tires on and hit a dirt road or maybe even some single track.

    What's fattest tire I might expect to use (and need to accommodate in the rear end), What are others using?

    Thanks

    Could think about a 650bx42 and 26"x2.25" swap.

    Simple solution to your problem.

    You have a 700c Axiom (if I recall correctly).
    You need a 650b Evergreen (with a dropped or chopped chainstay which will allow lots of tire clearance).





    *I might also be projecting onto you be because my mid-reach rim brake Axiom only fits 32mm tires or 28mm tires with fenders so I may need an Evergreen as well sometime in the future.

    The current benchmark is 650bx2.1 for gravel clearance. Many interesting tires to choose from in the 42-53ish range.
    Lots of capable 48s (Compass, Terrene, WTB etc) and some super fun 2.1s (ThunderBurt, Black Mamba, etc). A 42 is still wonderful for a day without a plan.

    There are a couple gravel rigs that go even wider than 2.1, but they are outliers.

    Maybe check out the Ibis Hakka MX or the recently revamped Santa Cruz Stigmata.

    Another vote for the 650b x 42, 559 x 54 dynamic duo.

    I would factor max tire, and narrowest (Q factor) crank.

    I’d say the bike is closer to an Evergreen than an Axiom at this point. Seven did some work on it a few years ago to tweak the rear triangle to get a little more space, but 42 is the max I think.

    What kind of terrain are you going to ride? How much do you weigh and what is your height? Those are all going to come into play when choosing the perfect wheelsize/width/outer diameter for a clean sheet build.
