• Are you absolutely sure you want/need an insert for the front?

    No, but in the same fashion that I already have 2.6 on, I also already ordered a 2x set of Cushcore XC so figure I may as well fit both. I was contemplating leaving the 2.6 with no insert but then I'd need a 2.6 tube and 2.4 tube (unless 2.4 tube works in 2.6?)

    But fair doos really, after what skinny said about riding at night while tired, it could save you.

    I don’t really know about fitting the xc insert into a 2.6” tyre. I’d imagine that it will still offer what it’s supposed to, but maybe to a slightly lesser extent in term of overall rim protection since the insert has less material on it.
    It should still do the same job in terms of keeping the tyre bead locked into the rim.

    You probably already know this but inserts (especially cushcore) can be an absolute cunt to fit. I run Rimpact inserts on one bike and cushcore on another.
    First attempt on fitting both brands took well over an hour and both my thumbnails were bleeding.

    I think it’s pretty unlikely you’ll have a tyre bead pop off the rim during an ultra, but if it happens, there’s not much chance of getting an insert back on the rim with the tyre seated.

    I’ve popped a tyre off a couple of times mid ride and the only way to continue was to take the insert out and ride back with it over my shoulder. Food for thought.
