B-RAD | Flexible On-Bike Storage

B-RAD Wolftooth

Thinking outside the box . . . a metaphor that means to think differently, unconventionally, or from a different point of view. The folks over at Wolf Tooth have once again donned their thinking caps, thrown caution to the wind and challenged the status quo with their Bottle Relocation and Accessory Device (B-RAD) on-bike storage system.

This innovative product uses the water bottle mounting points to maximize storage on your fattie. Fatbike Republic was fortunate to get its paws on a selection of goodies from the B-RAD system to see how it fares in the world of fat.

Mounting Bases

The key to the entire B-RAD system are the mounting bases. Made in the USA from 6061-T6 aluminum (also used in aircraft fittings) these bases come in three sizes B-RAD 2, 3 and 4 and are compatible with standard 64mm bottle cage braze-ons.

The B-RAD 2 is the shortest of the rails measuring in at 5.15 inches (131mm) and weighs in at 24g which is a little lighter than the claimed 27g. It is a two slot base with two threaded holes (M5 x 0.8) and comes with four 18-8 stainless steel bolts in two lengths. It primarily claim to fame is to optimize water bottle location in a smaller frame or to mount one of the B-RAD accessories.

The B-RAD 3 is the midsized rail and measures 7.95 inches (202 mm) weighing in at 39g (claimed 41g). This base has three slots and four threaded holes and comes with a closed cell neoprene foam pad and zip ties for secure mounting. Supplied stainless steel bolts mount it to the frame. This base offers additional mounting points over and above the B-RAD 2 and is perfect for mounting a water bottle and B-RAD accessory in tandem. This one is probably the most versatile of the three.

The B-RAD 4 is the supersized rail offering nine threaded holes with four slots. It measures 12.1 inches (307mm) long and weighs 73g. It also comes with the neoprene foam, zip ties and stainless steel bolts. This rail offers the maximum flexibility and storage capacity.

To get a true picture of how these rails will fit your bike, Wolf Tooth has provided printable template so that you can select the right mounting plate(s) for your ride.

Strap and Accessory Mount

The Strap and Accessory Mount simply holds stuff. Mounted to a B-RAD rail, the heavy duty velcroed strap and EVA foam pad can securely hold any number of items up to 80 mm (3.14in) in diameter . . . which is a little bigger than a standard water bottle. It weighs 41g, comes with two 18-8 bolts for mounting and pairs well with the Double Bottle Adapter.

Prior to mounting it to a B-RAD rail you thread the nylon strap through the slots in the mounting base. The nylon strap is textured on the inside to give superior grip.  The base also has two raised ridges (visible in pic) that slip over the edge of the B-RAD rail to ensure that it stays in place.

Double Bottle Adapter

No need to guess what this B-RAD accessory does . . . the Double Bottle Adapter allows you to run two water bottles side by side for those thirsty days on the trail and at 18g it weighs practically nothing. There are two longer stainless steel bolts for mountain to a B-RAD rail (or to the regular water bottle mounting points) and four shorter bolts to mount your two favorite water bottle cages. And like all Wolf Tooth products these are made in the USA.

How to use it

First is to figure out where to mount the rails. Now I'm sure some of the long distance bikepacking rigs have braze-ons every couple of inches, but common areas to find them on fatties include on the top of the downtube (in the frame), under the downtube, on the seat tube (inside the frame) and on the fork blades.

Frame opening sizes vary by manufacturer and the actual frame size itself. The Sasquatch 6.1 has a small frame opening for its large size. Getting a frame bag to fit this bike is a task, and storage would be minimal. But using small and midsize B-RAD rail allows for extra gear to be carried.

On the other hand, the Gros Louis 2 has a much larger frame opening which can easily accommodate the larger B-RAD 4 rail and subsequently can carry more gear. With all the different frame geometries there will be at least one B-RAD rail that will fit. As mentioned above, the printable template will allow you to test fit before you buy.

While the supplied bolts mount to the water bottle braze-ons, they actually fit inside the B-RAD rail slots.  This allows you to easily fine tune the fit by loosening the bolts and sliding the rail.

The fork blades offer probably the best location for placement of the B-RAD 4 as there are no space restrictions. The only consideration would be the weight limitations on the front fork.

The Double Bottle Adapter was very easy to install on the B-RAD rail. I did notice that depending on the frame geometry and location chosen, sometimes it was easier to install the Double Bottle Adapter on the rail first and then install the rail on the frame. It mostly had to do with getting room to spin the bolts.

Strap and Accessory Mount can run solo on the B-RAD 2 or will pair up well with the Double Bottle Adapter on the B-RAD 3 and B-RAD 4. The actual length of the item you plan to carry would determine which rail to use and where to mount it on the bike. 

In Use

Mounting the B-RAD rails in different locations with different accessories gives you endless options. 
The Double Bottle Adapter was mounted on the fork, high in the frame, low in the frame and under the downtube . . . on various rails.

With the wide q-factor on the fatbike I did not hit the bottles with any moving body parts while riding, mounting or dismounting.  When mounting up the B-RAD 3 and 4 its important to use the neoprene foam pad and zip ties to further secure the rail to the bike.

I can see a Double Bottle Adapter on each fork (mounted high) would benefit long distance treks with quick access to four water bottles.

The Strap and Accessory Mount looks lonely on its own and was better paired with the Double Bottle Adapter.  Using an old water bottle (or similar container) to stuff in bike tools gave the Strap and Accessory Mount a unique purpose. If mounting to a fork blade, much longer items could be carried like axes and portable saws and even fishing rod cases for when heading out to your secret fishing hole.  Mounting heavier items lower in the frame does keep the center of gravity lower.

Out of the various combinations I found that for every day trail riding the frame mounted B-RAD 3 with the Double Bottle Adapter mounted mid-bike and the Strap and Accessory Mount below (sporting a spare tube) was the best combination.

Having the extra water bottle at my fingertip was very much appreciated on warm riding days and moving the bike tube made my backpack lighter.

And the system is tough.  I had an OTB experience that ended in a trip to the hospital for me . . . yet both water bottles, the rail and accessory mount escaped without a scratch.

Final Thoughts

As I understand, the Double Bottle Adapter and Strap and Accessory Mount are the tip of the iceberg for Wolf Tooth and their B-RAD system. 

There is practically an endless number of mounting configurations using the B-RAD system, so the end use is really up to you.  As I head out on different adventures I'm sure that I will discover new configurations to suit the ride and my needs.

Fatbiking Safety | The Unexpected Crash

Fatbike Crash and Safety fat bike crash

I'm guessing that when most of us hop on our fatbike to take a spin, getting into an accident or putting ourselves in danger is the last thing on our mind. Grabbing a helmet and ensuring the cell phone is charged is probably the extent of most people's safety planning.  I recently learned the hard way that you need to be prepared as accidents can happen at any time.

Not long ago I put a good dent in the "honey do" list and ended up with a little time to kill in the afternoon.  As the weather was great I decided to head over to a local mountain bike trail that I frequent and bounce around for a couple of hours on some of the unfamiliar side trails.  I contacted a couple of buddies, but they were tied up so I went flying solo.

When I hit the first side trail I encountered some rocks and semi-technical downhill sections.  As I expected these types of challenges I was riding in the attack position which allowed me to shift my weight around and stay upright on the fattie.  I'm no speed demon . . . but I had fun.  With one trail down it was off to find the second one on my to do list.

This one was more of a meandering trail through the woods with a couple of rocks thrown in for visual interest.  I was pedaling along on the trail and spied a small rock ahead and decided to roll over it on the right.  As the front tire crested I knew I was in trouble as there was an unexpected drop.  My weight shifted forward and OTB I went . . . face planting in the dirt.  I was alone, without a cell phone, bleeding, had minimal medical supplies and on a trail that was not well used.

Fatbike Crash and Safety

I surveyed my injuries (nothing broken), cleaned my wounds (flushing with water bottle), found my broken riding glasses and hobbled back to my vehicle with an uninjured bike.  It was off to the hospital where I discovered I needed eight stitches in my forehead.  I also had a broken nose, broken bone under my nose and multiple facial cuts scrapes and bruises.

CAUTION - The following video contains graphic images.

Click HERE to see the 3 minute uncut crash footage.

As I was healing I realized that the situation could have been much worse. It was time to review my trail riding safety list.


Its always best to ride with a buddy, but at times we have to ride solo.  If a trail side accident occurs your buddy can help triage the situation and get you back to safety.  This luxury is not available when riding alone.  When flying solo I ensure that people know where I am going and approximately how long I will be gone.  Leaving a Google Map of the area with a loved one and a contact number of a riding buddy who is familiar with the area is extra insurance.

I'm not a lover of cell phones, but they can provide an important lifeline in case of an accident.  However, you need to be conscious and have cell service for it to be of any benefit.  For those who do carry a cell phone on their fatbike outings there are several GPS tracking services that can send "crash alerts" to programmed people in case you take a tumble.  And having your name and contact information on a piece of paper somewhere on your person would greatly help any passerby who may find you in an injured state.

Fatbike Crash and Safety

In addition to snacks, tools and a spare tube . . . a first aid kit should also have a place in your off-road fatbike excursions.   Although slapping a bandage on scrape may not be necessary, I wish I had a larger bandage to cover the gash on my forehead after the tumble.  Find a kit that works for you and squirrel it away in your backpack.

I know that many of us just grab the fattie and go, but a quick pre-ride bike check is always a good habit.  Its better to notice that loosened pedal before the ride than out on the trail after picking yourself up from the dirt.


I never ride without a helmet, but surprisingly some people do.  I think those folks are crazy as a rock will win against a skull every time.  Some manufacturers recommend that you replace your helmet every 3-5 years while other say that may be a conservative time frame.  However, it is widely accepted that a helmet should be replaced after a crash.  

I'm certainly glad that I was wearing my riding glasses when I took my recent tumble.  They flew off my face after impact and when I found them I discovered one of the lenses had popped out.  I shudder to think what would have happened if I had not been wearing eye protection.  During many a ride my glasses offered additional protection from dust, rain, wind, bugs and the errant tree branch.

Gloves.  Some people hate wearing gloves, I can't ride without them.  Landing after an OTB superman my gloves were covered in dirt, rocks and twigs.  They certainty would have been in worse shape if I had been flying naked.  Gloves also reduce rubbing against the grips and offer additional protection when scrambling up or down rock faces.

Shin protection.  I'm pretty sure that most people have felt the bite of pedal pins on your shin after missing a pedal stroke.  Its definitely not pleasant.  I experimented with a couple of bike specific shin/knee protection options over the years and discovered soccer shin protectors fit my riding style.  They are light, not as warm, don't move around and many have built in ankle protection.


The main reason why I went OTB was that I was not paying close attention to the trail.  It was an unfamiliar trail and its non-threatening meandering nature tricked me into not paying attention. Its also easy to become complacent when riding a familiar trail, as they too can serve up a surprise when you are least expecting it.

When riding its best to pay attention at all times and expect the unexpected.  And even if you are paying attention there is no guarantee that you will not take a spill.  Everyone goes down from time to time.


My unexpected impact with terra firma could have been much worse.   I will be left with a scar reminiscent of a lightening bolt over my right eye as a permanent reminder.

I will be taking a look at the Giro Switchblade and Bell Super 3 as they offer interesting convertible helmets that cross riding styles between trail and downhill.

I will be researching lightweight body protection and will probably supplement my riding gear.   I want to increase protection, but not to the point of riding around like a jousting knight.

My first-aid kit will be much better stocked for the next trail side experience, and I may have to invest in a cell phone (sigh).

Be safe . . . have fun . . . ride on!

Snow Avalanche 4.0 - Dirt Loving Rubber

During the winter season Fatbike Republic had the opportunity to test a set of the new Vee Snow Avalanche 4.8 PSC studded tires. Impressions were quite favorable on this new tread design from Vee.

Now that the snow is gone, Fatbike Republic secured a pair of 4.0 Snow Avalanche in a silica non-studded version to see how the tire handles the non-white fatbiking seasons.

Be sure to check out the ride video below !

The Tire

The Snow Avalanche is available in two sizes (26 x 4.0 and 26 x 4.8) and in both studded and non-studded versions.  According to the folks at Vee Tire:

The Snow Avalanche features an aggressive tread design for enhancing steering performance and off-camber grip. With a low rolling resistance and excellent float, this directional tire is great for blocked trails or loose snow.

They are also available in two types of rubber compounds: Silica and Pure Silica Compound (PSC) with the off-white PSC being more supple and focused more on winter performance.


The tires sent for testing were the 26 x 4.0 Silica (black) version of the Snow Avalanche.  With a hardness rating of 57A the rubber maintains low resistance and flexibility in all temperatures.  For comparison purposes a car tire tread measures 60A and a pencil eraser has a hardness of 40A.

These tires are tubeless ready, directional and have a folding bead.  A thread count of 120 makes them more supple than tires with a lower TPI. And if you enjoy studding tires, there are 240 stud pockets for you to fill with your favorite stud.

This is a totally new tire for 2017 and Vee looks to be heading in a new direction with tire design.  A quick look at the tire reveals smaller more square edged lugs that would appear to give more biting surfaces.

Running down the center of the Snow Avalanche are alternating dual and single lugs, with the single having a modified chevron pattern blending into the first transitional row.  The alternating beefy square edged lugs of the first transitional row and the square edged rhombus lugs both contain stud pockets.  The Avalanche's shoulder alternates between large and medium vertically oriented rectangular knobs.  These lugs are slightly concave towards the center of the tire.  For some extra traction the transitional portion of the tire carcass has been textured.

The claimed weight of the Snow Avalanche 4.0 is 1300g and when dropped on the scales it actual weighs in at 1283g.

Mounted to an 80mm rim with 8psi the 4.0 Snow Avalanche measured 3.76” in width.  Tread depth is around 0.17" for the center treads to 0.26" for the shoulder lugs.

Field Test

If you are looking for testing of the Snow Avalanche in winter conditions, head on over to the Snow Avalanche 4.8 PSC review.  It’s one sweet tire for the snow.

These black beauties were mounted to a Norco Sasquatch 6.1 sporting 80mm alloy rims.  Tire pressure remained pretty consistent at around 9-10 psi for general trail riding to 15 psi for hard packed gravel grinds.

Heading to the local mountain bike trails the Snow Avalanche handled the obligatory climbs with ease.  While no featherweight, these tires were easy to spin and lift over trail born obstacles.  The smaller lug size, coupled with the sharper edge profile (no ramping) allowed the tire to grip roots and rocks and keep the momentum flowing.  There was very little if any “skidding” on dirt and rock off-cambers as the heavy shoulder lugs provided plenty of grip.

The modified chevron pattern (reminiscent of the Endomorph) when run in the recommended direction – chevron pointing forward when looking from above – should theoretically provide better braking traction and less rolling resistance.  When run in reverse - chevron pointing back when looking from above – the tire should provide better climbing/mud traction.  I did notice that the tire seemed a little quicker when running in the recommended direction.

These tires also performed well going through the wet and slimy. The lugs churned through the mud and cleared quickly.  The silica compound and sharper squared lug pattern minimized slippage over hard wet surfaces.

When running high psi for gravel grinds these tires rolled really quickly on the center and first-row transitional lugs.  Turning the bars had the fattie running in the intended direction and there was no noticeable washout.  One rider said that the bike feels like it is on rails.  These tires can corner.

Final Thoughts

Don't let the name of these tires fool you.  
After considerable dirt time in the saddle with the Snow Avalanche, I have to say I’m really digging the new tread design from Vee Tire.  They provide plenty of traction, corner well and roll fast.  The smaller sharp edged lugs love the dirt.  The Snow Avalanche would make a super OEM tire for new fatties.

Although not tested in the snow the Snow Avalanche 4.8 PSC proved to be one formidable winter fatbike tire.  The 4.0 Silica version should also do quite well.  If you plan on studding these tires, be sure to do it before riding them as small rocks and dirt pack the stud pockets.

If you are looking replace your worn out 4" tires, or looking to shed  your winter 5" for a snappier 4" tire . . . be sure to check out the Snow Avalanche 4.0 by Vee. 

Ride on !
