White Industries T11 Hubs and Boyd Altamont Ceramic-Coated Rims: A Sensible Choice for Rim Brakes

With all of the focus on disc brakes these days, you might think that no one was still riding rim brakes, but that's just not the case.  In many cases, rim brakes have advantages (light weight, and compatibility with older frames among them), and there are actually a lot of great hubs and rims available.  One of our favorite combinations is the Boyd Altamont Ceramic coated or Altamont Lite Ceramic coated rim and the White Industries T11 hub

Boyd Altamont Lite Ceramic coated rims and White Industries T11 hubs make for sweet rim-brake wheelset.

The Altamont and Altamont Lite are both available in a disc or rim brake version, and the rim brake version of each is available with a standard machined brake track with a black anodized finish or a special ceramic coating that covers the entire rim.  Not only does the ceramic coating look like some kind of stealth technology, but it improves braking performance in wet weather and makes the whole rim more durable.  Like the ceramic-coating that Mavic used beginning in the 90's and continued to include on their high-end wheels well into the 2000's, these rims need to be used with special pads (which are included with the rims), and really do give impressive all-weather braking and more durable brake tracks.  On top of great braking and durability, the rims are tubeless-ready, have a welded seam, and a nice modern aero profile and width.  

White Industries' T11 hubs are lightweight, easy to service, their titanium freehub drivers are available in every major standard.

And so you can run whatever drivetrain you like, the White Industries T11 hub is a great option.  Its titanium freehub driver is extremely durable, so it's unlikely that you'll ever need to replace it unless you decide to change drivetrains.  If you do decide to make the switch though, it's available in Shimano HG-11, Campagnolo, and Sram XDR designs and it's easy to swap, so changing it to a new system is a cinch.

We've got these rims as options in our AVT Works Road Wheelset, and as individual rims, but of course, if you would like us to build you a wheelset that you don't see available, just get in touch!  We love building custom wheels that get you just the configuration that you're looking for.

Wolf Tooth Morse Cage: Adjustable and Light

A perfect collaboration

Titanium King Cages need no introduction: they're just the most durable, simple, and lightweight bottle cages on the market.  It's little wonder, then, that Wolf Tooth wanted to collaborate with Ron and company to make their adjustable Morse Cage.  The Morse Cage is essentially a standard bottle cage with the ability to move it up or down by up to 1.25", and while that may not sound all that groundbreaking, it can be incredibly useful.  The adjustment can make all of the difference on a frame with limited bottle clearance (such as a small frame or many full-suspension bikes), and it also just gives you the ability to fine-tune where exactly your water bottles sit on the frame.  The latter point can determine whether you're able to run a large water bottle on a frame with bosses that aren't positioned in the ideal location.

The Morse Titanium Cages are a great example of a small, but important improvement on a part that we already love.  You may not need them, and in that case, the standard Titanium King Cage is still a great way to go (it's 4g lighter-weight, and $10 less-expensive after all); but if a little bit of adjustability would improve your riding experience, the Morse Cage is well worth it.  We think it's a really useful and thoughtful part that makes a big difference where it's needed, so we're glad that it exists.

Custom means custom when it comes to AVT WORKS custom wheels

We offer a wide range of wheels–both sourced from the likes of Enve, Chris King and Astral, and our own AVT Works custom–but there are times when even our custom options won't quite get you the wheelset you've been dreaming of.  At times like those, just get in touch, because we're always happy to get a different spoke, rim, or nipple so that you get the wheels you really want.

Chris King / DT Swiss Wheelset

This wheelset is for a rider who wanted a rim that we don't usually offer, but which was the perfect choice for his use.  The result is this beautiful 27.5" wheelset built with Chris King ISO-B rear and ISO-AB front hubs laced to DT Swiss EX471 rims.

Industry Nine / Stan's Wheelset

Recently we talked with another rider who was tired of waiting for Chris King's Micro Spline driveshell to arrive, but who wanted a top-quality, fast-engaging, US-made hub, so he asked us if he could get what is essentially the standard Chris King / Stan's Flow MK3 wheelset, but built around Industry Nine's Hydra hubs. We're building the wheels, and we think that will make a fantastic wheelset, so of course we were happy to oblige!

Industry Nine Hydra hubs, Sapim Race spokes, and Stan's Flow MK3 rims are going to make an awesome wheelset.

One of the reasons that you might want something custom is for colors not available in any other wheelset, and Industry Nine hubs have some of the best anodizing in the business, as this deep red attests.  You'll see some options, like the Enve/Industry Nine M-Series wheelset we offer, where the hubs and spoke nipples are only available in black, but if you want that wheelset, but built with hubs of a different color, we're happy to build them for you.

Phil Wood / HED Single Wheel

One other recent build that was completely different, was this Phil Wood Pro hub on a HED Belgium C2 rim.  This rider just needed a single super-reliable rear wheel in a configuration that we don't normally offer, so they gave us a call.  We worked out the best combination with him, and built the wheel.

These are just a couple of examples of completely off-the-menu wheelbuilds that we've done recently, but the they're just a couple of the wide range of options that we can do.

What Makes a White Industries R30, G30, or M30?

White Industries offers a really wide range of cranks, from their square taper ENO and VBC cranks, to their 30mm-spindle R30, G30, and M30 models.  In this post we wanted to take a look at what the actual differences between the three 30mm-spindle cranksets.

Most of us have gotten used to not having any control over the q-factor, and at best minimal control over the chainline of our cranks because modern 2-piece cranks tend to not have any means of adjusting these factors.  Because White Industries uses separate crank arms and spindle, and because those both pieces come in two different versions, you actually do have some measure of control over those factors.

White Industries G30 and M30 arms and Road/Gravel spindle: these are the parts that make up the R30 and G30 cranksets

For starters, let's look at what defines each model:

R30: R30 (narrow) arms, Road/Gravel spindle (for 68mm and equivalent bottom bracket shells).

G30: M30 (wide) arms, Road/Gravel spindle (for 68mm and equivalent bottom bracket shells).

M30: M30 (wide) arms, Mountain spindle (for 68/73mm and equivalent bottom bracket shells).

From this small list, you can see that the G30 crankset provides more chainstay clearance than the R30 crankset by using the same arms as the M30.  As an example of how you might use this information, we've found that many times gravel bikes don't actually need the extra width of the G30 cranks, which means that if you would like to get the narrowest q-factor possible you have the option of using the R30 version.  But what does any of this actually mean, and how can you decide for yourself which crankset will give you the fit and feel that you're looking for?  Read on to find out.

In the photo above, you can see how much more the upper crankarm bows out.  That's the M30 crankarm, which as noted in the list, is used to make the G30 crankset as well as the M30 crankset.  And as you can see, the difference between the G30 and M30 cranksets is the spindle they use.  It's really that simple.  One very important thing to note is that the Road/Gravel spindle is only compatible with 68mm bottom brackets (and their equivalents in T47 and PressFit standards), whereas the Mountain is compatible with 73mm (and its equivalents in the other standards).  For more on bottom bracket compatibility, check out this compatibility chart.

White Industries has handy technical drawings with measurements for the three cranksets, which is a very useful tool to help you decide which one will best suit your needs.  They also list the q-factors for all three, which, for those who care, is very nice indeed!

If you look at the drawings, you'll see that the road crankarms have a 12.5mm narrower q-factor than the mountain/gravel ones. This is the actual difference in q-factor that results from the different shape of the arms, so it's the difference in q-factor between the R30 and G30 cranksets, because they use the same spindle but different arms.  With so many bikes these days being designed with s-bend chainstays, it's often not necessary to have as much clearance between the crankarms, making it possible to run the narrower road arms on your gravel bike.  For some riders, getting a narrower q-factor is an important part of leg and knee comfort on the bike, so we think this is important to know.

For us, the natural next question to ask is whether you could, or would ever want to run the road arms on your mountain bike.  Of course, with many older mountain bikes, you'd be able to install a standard road or gravel cranksets (assuming the bike has a 68mm bottom bracket), but you would need to check beforehand to make sure you'd have clearance at the chainstays.  This is where the detailed drawings are so helpful.  One important consideration with this is that using R30 or G30 cranks on a mountain bike would give you a chainline that is 2.5mm farther inboard than you would get using the mountain bike spindle.  Just to stir up this already-cloudy topic, if you wanted to do this while maintaining your standard 49mm mountain bike chainline, and you were using a 1X setup, you could install a boost chainring in place of the standard non-boost one.  Of course if your bike uses a boost drivetrain, this wouldn't be possible, so it would be better to just go with the standard mountain spindle.  All of this is possible because on White Industries R30, G30, and M30 cranks, chainline is determined by spindle length and chainring offset, and not the crankarms.

But say, just for kicks, that you really like the narrowest q-factor you can get, but you have a 73mm bottom bracket shell, so you have to use the Mountain spindle according to the bottom bracket compatibility chart.  You've measured your frame and you've looked at the White Industries' technical drawings where you've seen that the M30 cranks have a measurement from the centerline of the bike to the inside of the crankarm tip (the X2 measurement) of 74.8mm, but the road cranks have an X2 measurement of only 66mm. If you add 2.5mm to the road X2 measurement you can see what it would be if you substituted the mountain spindle spindle for the Road/Gravel one in that R30 crankarm. The result is 68.5mm for the X2 measurement. That's pretty narrow, but definitely not unheard-of for a mountain bike, so you might just be able to get your mountain bike set up with a q-factor of only 163.5mm by using R30 arms and a Mountain spindle.  Just be sure to measure well!

In the end, we've found that most riders are quite happy with one of the standard options, but we find it helpful to know what's actually changing when you go from one model to the next, and we hope you do too.  If you ever have any questions, or if you would like to get a special build, just get in touch, and we'll help you get the build you need.
