Project Wide Gravel Wheels

Well.......look at that, would ya?

Okay.......White Industries came through. I have the hubs in hand and now, as I am wont to do, I have instigated another "project". This one will be a wheel build to test my theory on wide rims for gravel.

Before I get into my hypothesis, let's take a look at these gorgeous black anodized goodies here, shall we? Of course, they are from White Industries and are their new disc hubs dubbed "XMR". What does that stand for? Who knows! I would say, "good looking", sleek", and light weight, but none of those terms start with "X" "M" or "R". White Industries says the hubs have a 6-4 titanium free hub body, a six bolt disc rotor interface, available swappable end caps for through axle compatibility, or as in my case, the standard traditional quick release caps which are included, and an 11 speed compatibility with backwards compatibility to 10 speed and 9 speed cassettes via an included spacer. Pretty swank looks, if I say so myself, with laser etched graphics, and an availability in a few different anodized hues to boot. I chose black so I can swap these wheels, when they are built, between multiple bikes if I so choose and they will look great in all of them. I must say that I was sorely tempted by the option of getting White Industries XMR hubs in luscious purple ano though!

These hubs came highly recommended to me, but of course, there are more things to a wheel than hubs. I also chose WTB's KOM i25 rims for this build, and here's where it gets interesting, as far as my theory goes here. First, you need to know that WTB KOM i25 rims are 25mm inside width, so they are pretty wide rims! Keep in mind that most road-ish, cyclo-cross rims run in the 17mm-19mm inner rim width territory. Yeah......these are wide rims!! Well, for 35-40mm tires, they are wide rims. And see......that's the thing, everybody is going wide and wider off road, so why not for gravel? I mean, a 30mm wide rim is considered XC-ish these days and 35-40mm inner rim widths are commonplace on trail bikes. Every road rim that is introduced gets wider as well. So, it only follows that gravel riders might be benefiting from the same ideas, right? Well, we will see......

KOM rims come in several widths and diameters, but I chose the biggest and widest!

I figure we can look at gravel road tires as "plus sized road tires", so wider rims make sense to me in that vein. My hope is that the wider KOM i25 will do for the 38mm-40mm tires I intend to use on them what the wider mtb rims and 27.5+ tires did for my "Fat Fargo". Those corpulent wheels transformed the Fat Fargo into a rough terrain eating machine. Maybe wider rims will help stabilize gravel tires and help them roll over loose, deep gravel at lowered pressures better than they do on more traditional width cyclo-cross or road rims, the likes of which I have been using. Maybe that will translate into a more comfortable, less fatiguing ride quality which will help me out on longer rides. That's the hope and what I intend on finding out.

So, stay tuned for a detailed wheel build post, then I'll pop on some bigger gravel going rubber and then these will be featured first on my Twin Six Standard Rando, but I fully expect to also use them on my Raleigh Tamland Two and my Gen I Fargo.
