Cavery Cab

After starting a family, it can be difficult to keep riding like you did before the baby arrived. It’s not always easy or affordable to find a babysitter, and so you often find you and your spouse taking turns out on the trails. Local riders Cullen and Melissa Jones were determined to keep riding after the birth of their son though, so they designed and built the Cavery Cab, a single wheeled, off-road bike trailer. The trailer went through a few prototypes, until finally the Cab got the Cavery seal of approval. The latest design works great over smooth singletrack, even over uneven terrain.

Cavery Cab

Think a Cavery Cab would work good for your family? Cullen will build you one!  Here are some details on the Cavery Cab from their website:

The Cavery Cab is a single wheel bike trailer serving as the ultimate mountain bike trailer for families. It was inspired by the birth of our son Cavery. We realized that we needed special gear to help us continue enjoying our favorite trails as a couple- and now as a family. Encouraged by our son’s total love of all things outdoors and with wheels, we set out to find a trailer that would allow us to bring him with us on our bike rides. Unable to find a trailer that met our criteria, we resolved to make one. After testing various designs, we finally have the single track trailer with features we all want- safe, smooth, comfortable, and fun!

Cavery Cab

The trailer works using a single-wheel design and attaches to the seat post of a rider’s bike, allowing you to ride single track trails. It is fitted with a rear suspension shock giving a smooth ride over uneven terrain. The trailer attaches to seat posts of 31.6 mm and 27.2 mm diameter using the appropriate adapter sleeves. A child of up to 40 pounds rides in a Graco or Cosco Convertible Car Seats which can be clipped to secure points on the Cavery Cab frame.

Cavery Cab

Cullen made and tested several prototypes of the single-wheel suspension kid trailer until he found the right combination of features that gave the smoothest ride on all types of terrain for …both rider and trailer. The Cavery Cab has allowed us to share many special moments together outside and off road. As we ride the trails, we continue to meet riders who would like a Cavery Cab either for taking along kids or gear where ordinary bike trailers can’t go. If you would like one, just let us know! Happy Trail Riding!

WTB Wolverine 29″ Tire – Final Review

Back in November of 2009, I wrote about my initial impressions of the 29″ (29×2.2) Wolverine tire from Wilderness Trail Bikes HERE.  I’ve had over a year on the Wolverines now, using them as a front and rear tire, and riding them on all sorts of terrain.  Here are my final thoughts on the tire.

Silver City Loop
Conquering the Mud Hole

Traction

Throughout the year, I got to try the Wolverines in snow, mud, sand, hard pack, and asphalt.  These tires handled all these conditions well, making them a great choice for all-terrain applications.  The tread pattern of the Wolverine provides plenty of bite no matter what angle the bike is at, from straight up, fully leaned over, and everywhere in between.   The tire feels very predictable and confidence inspiring all the way through a turn, progressively biting harder the further you lean the bike over.  The squarish profile of the tire further enhances contact with the ground, especially when combined with lower pressures. These same qualities help stop your bike quick when it’s time to brake.

The Wolverines do pretty well on the asphalt as well. I frequently ride my mountain bike on the road to the local trailheads and around town, so having a versatile tire is important to me. You can descend and corner with confidence whether on high speed road descents or just zipping around the city streets.

Snow Print

Rolling Resistance

The moderately spaced tread of the Wolverine allow the tire to roll smoothly without the bumpy knobby feeling of a more openly spaced tread pattern. Because of this, the tire feels lighter than it is.   The tread is still aggressive, but the knob spacing works well in all conditions, whether riding through snow, mud, sand, hard pack, or transitioning through a combination of these terrains.

Weight

My test tires weighed in at 805 grams and 840 grams. This takes them out of the race tire arena, and puts them into the trail riding category. You may not set record hill climb times with the Wolverines, but it’s still a tire that you can pedal on all day epic rides comfortably. Light enough for climbing performance, large enough for plush comfort, aggressive enough for varying conditions. The new advertised weight is 774 grams, so it looks like WTB was able to shave a little weight off since the first production run. WTB mentioned that they were surprised at the initial weight as well. Running the tires tubeless also helps get the rotating mass of these big hoops down.

Durability

I began this review back in the Fall of 2009, and I’ve ridden these tires every week since then. I used the Wolverine as a front tire for several months as I wore out a couple rear tires. I finally ended up moving the Wolverine to the rear to get a “little bit” more use out of it, but I’ve ended up riding it an additional half a year! I can honestly say the tire is done now though. It still corners great, but the center knobs are worn down to the point where it’s slipping on climbs and during braking. It was a great value to get this much use out of a tire. Especially one that works well as a front or rear application.

Amazing traction, front or rear

Going Tubeless

Although these tires are not part of WTB’s tubeless tire lineup, I’ve ridden them tubeless for over a year with no problems using Stan’s NoTubes Sealant. The tires sealed easily, held consistent air pressure for several days, and have never once had a puncture. They were mounted on On One standard rims for the first part of the test, then Sun Ringle Black Flag tubleless ready rims for the remainder of the test. Dropping extra rotational mass by going tubeless was noticeable. It got the weight into that sweet spot where the wheel accelerates quickly without feeling sluggish. I typically ran the tires at 25psi in the front, and 30psi in the rear.  This flattens the tires out nicely for optimal traction with no fear of pinch flats or rim damage.

Summary

As a front tire, the Wolverine is fantastic.  It’s a perfect blend of traction, low rolling resistance, large volume, and durability. It’s not as plush as the big WTB Weirwolf 29×2.55 LT I’m running now, but the Wolverine definitely has superior traction.

As a rear tire, the Wolverine may be overkill depending on your conditions. With their already larger footprint, 29 inch wheels are not short on traction.  The lightly treaded 29″ WTB Nano Raptor I enjoyed last spring and summer hooked up well in most situations, and saved me quite a bit of rotating mass.  Switching to the Wolverine in the Fall slowed me down a bit, but it was nice to have more traction in the deep Fall sand and the snow and mud of Winter.  Light fast tires don’t buy you much if you’re spinning out when you need traction the most.

I will definitely purchase more Wolverines in the future, especially for front tire applications.  They hook up in a wide variety of conditions, roll well, are durable, and weigh in at a reasonable weight for all-around trail riding. Additionally, the large volume casing provides a comfortable ride, floats over the sand and other soft surfaces, and protects the rims well. Highly recommended!

Shimano Electronic Shifting

Back in May, Felt Bicycles brought their demo van to Carson City, and one of their demo bikes was equipped with Shimano’s electronic shifting. Although I had heard of electronic shifting for a while, this was the first time I got to actually see it in person and try it out. This is by no means a full review of the product, simply the initial impressions I got while riding a couple laps around the parking lot.

Shimano electronic shifting
The front derailleur – the “brains” of the system

Getting used to the hand controls took no time at all, since the lever/button are basically the same (although with less movement than on a mechanical system). The same levers you’re used to on your mechanical system make the shifting go the same direction. The only real difference is that you’re sending electronic signals rather than pulling on a cable. While the rear shifting didn’t feel much different than that of a cable driven system, the front shifting action was definitely noticeable. Rather than ratcheting the chain up through the front chain rings with multiple clicks, you simply hold down the button. I think this was the feature that most made me think, “Hey…this is kind of cool.”.

Shimano electronic shifting
Battery Life Indicator / Fine Tuning

The front derailleur is what Shimano calls the brains of the system. Not only is the CPU located here, but it works in tandem with the rear derailleur. As the chain moves across the cogs in the rear, the front derailleur automatically trims for a constant perfect chain line. No manual trimming with the front shifter or rubbing on the front chain guide.

Shimano electronic shifting
Familiar Shifting Lever/Button

The rechargeable battery is mounted down below the front derailleur. The Felt rep told me that in the event of battery failure, the system shifts down into a middle range gear before dying, so you’re not stuck in one extreme. This could be good or bad depending on what terrain you’re stuck on. A small battery life indicator/fine tuner mounts to the cables below the bars.

While the battery and brain add a little weight to the system, weight is saved up on the bar shifters since there are less mechanical things happening up there. The overall system adds only a small net increase to the total weight (about 68 grams according to one Shimano document). Shimano also notes the possibilities of adding “remote” shifters at other locations on the bars. This may be kind of nice, since there are multiple hand positions on drop bars, and it would eliminate moving your hand back to the hood area just to grab a different gear.

Shimano electronic shifting
High end shifting for your high end bike

So what was wrong with high end road bike shifting that warranted an all new electrical system? Nothing really. A modern, well-tuned cable shifting system works pretty awesome, and is good for most of us. Although electronic shifting is definitely not for me, it does seem to work rather well. It also seemed to be the perfect match for the bike that it was on, making the feather-weight, full-carbon bike seem even sportier.

What are your thoughts on electronic shifting? Have you tried it? Is this something you think you’d want on your bike?

Brompton Folding Bike Review

Here’s an article by Dan Allison that was originally posted on the Muscle Powered blog. I’ve seen Dan’s Brompton around town, and I was really surprised just how small the bike folded down! We attended a meeting together and I had my huge Kona Ute. I was just beginning to wonder how Dan got to the meeting, when I walked into the conference room and saw the folded up Brompton tucked neatly away against the wall. Here’s Dan’s review of his new folding bike:

Dan's beautiful new Brompton

After thinking about it for more than a year, I finally bought a folding bike. It is a Brompton, probably the best made folding bike in existence, though Bike Fridays seemed pretty good too. I love it, love it, love it.

I’ve only taken one trip with it so far, from Reno to Sacramento and back on Amtrak, and it was a real pleasure. It tucked into the baggage shelf just fine. It folds down to the size of a medium suitcase, so works well for train, bus or plane (at least on Southwest, which is all I fly anyway). I’m going to fly with it for the first time in January, part of a trip to San Luis Obispo for Contra Carnivale. The rest of the trip is on train.

It was great to have a bike while in Sacramento. I rode the American River Parkway one afternoon, got to the conference I was attending (Safe Routes) on light rail and riding, and rode to dinner twice and the grocery store once. I’ve taken my road bike to Sacramento and even San Francisco before, but always had to use the bus to Sacramento because the only way to take full bikes on the Amtrak California Zephyr is to box them.

I’ve ridden a lot around Carson City, and everywhere I go I get compliments or at least comments, which was rarely true on my road bike. Kids especially think the bike is cool, and many ask me if they can ride it.

Though I test drove the bike for a couple of hours last summer, I was unsure about how different it would feel and handle from my road bike. My road bike is a 1971 Motobecane Grand Touring (made in France, 10 speeds, classic steel frame). The weight is not much different, and it doesn’t really handle much different. I lose a little power due to the small 16 inch wheels, and a little to a more upright riding position, but not much. Handling is a bit looser. not a bike to ride hands-free, but it tracks well. And it has fenders and wider tires, so it was no problem to ride it in a few inches of snow this morning.

I bought the bike from Channell Wasson in Palo Alto, who used to be the only US dealer, and the bike is made by Brompton in London, England. Channell spent about four hours with me talking about Bromptons and bikes in general, and I’d recommend him to anyone.

Interbike 2010 – Bar Mitts

With the freezing weather we’ve been having, here’s a cycling product you may be interested in. Bar Mitts are a weatherproof covering for your handlebars. The neoprene sheaths maintain their form, allow you to easily slip your hands in and out of them, and still allow you to access your bike’s brakes and shifters. Bar Mitts are even made locally just over the hill in Washoe Valley!

Interbike 2010 Las Vegas
Bar Mitts for Road Bars

From the Bar Mitts website:

BAR MITTS evolved from many years of hang gliding and cold winter rides. Hang gliding mitts are used on a straight steering control bar. During the cold months, I used my hang gliding mitts on top of my bicycle handle bars. However, as one can imagine, not being on the shifter and brake levers had its downfalls especially when it came to descents and emergency braking. For years, I designed various Bar Mitt prototypes that enclosed the shifter and brake levers. I am so pleased that the final product is now available for sale.

Interbike 2010 Las Vegas
Bar Mitts for Flat Bars

The freezing windchill is much greater during the faster speeds of a road bike, making it that much harder to keep your hands warm. There are other bar cover products on the market, but Bar Mitts is one of the few manufactures I’ve seen that creates an application for road bike style drop bars. This is good news for road bikers in Northern Nevada. Even in the dead of winter, we still have many sunny days that melt the ice on the roads and dry off the blacktop. When the snow gets too deep to ride off-road, hopping on the road bike may be our only option available. And since cold hands are one of the number one drawbacks to riding in the cold, the Bar Mitts may help you eliminate those excuses not to get out and ride this winter!

Interbike 2010 – Crank Brothers

When you think of the company Crank Brothers, the first thing that comes to mind are their unique Eggbeater pedals. Crank Brothers has been steadily releasing innovative new products though, and they have quite a lineup for 2011 including pedals, stems, bars, seatposts, wheelsets, and more! Here’s a sampling of products as seen at the 2010 Interbike expo.

Interbike 2010 Las Vegas
Eggbeater Pedals

Crank Brothers has recently changed their product naming conventions, switching to a more recognizable hierarchy of product level. Gone are the MXR, C, SL, and Ti names, replaced by 1,2,3, and 11. 1 is the entry level, the products becoming more exotic as the number increases, until the ultimate number 11 is reached. I believe “11″ refers to “that extra push over the cliff” that some desire, as documented in the movie, Spinal Tap .

Crank Brothers also has two distinct component groups, the Cobalt and the Iodine. Cobalt is the lighter weight XC group, and the Iodine group is heavier duty for the All Mountain/Free ride crowd.

Interbike 2010 Las Vegas
Candy Pedals

Pedals

Eggbeater pedals have undergone subtle design changes over the years, and have recently been updated to be stronger and more durable, able to go longer between service intervals. The Candy line, basically an Eggbeater surrounded by a small platform, has been much more obviously redone. The old multi-part plastic platform has been replaced by a machined aluminum body on the 2, 3, and 11 models. The Candy 1 pedals have the same look as the higher end pedals, but in a simpler 1 piece composite body.

Also available are the larger platform Acid and Mallet pedals, and a flat (no clip) 50/50 pedal.

Interbike 2010 Las Vegas
Cobalt Seatposts

Seatposts

A variety of seatposts are now available from Crank Brothers. The Cobalt posts have a simple, single bolt clamp, and come in aluminum or carbon. There is also the Joplin line of adjust-on-the-fly seatposts that allow the rider to quickly adjust seat height with a lever attached to the post or a remote on the handlebar.

Interbike 2010 Las Vegas
Iodine Stems

Stems

Crank Brothers offers one high end 11 Cobalt stem for XC/Race. It has a non removable bar clamp, and a single torx bolt tightens the stem on both the bars and the steering tube. This high-end carbon stem is very light at 125 grams, but the $300 price tag will keep it away from the masses.

The all-mountain Iodine stems are more affordable, but still at a weight typical of an XC stem. The 2 and 3 feature a single torx bolt design for the steering tube clamp, and a standard 4 bolt bar clamp. The Iodine 2 has an aluminum face plate, and the 3 has a carbon faceplate.

Interbike 2010 Las Vegas
Iodine 3 Stem close-up

Bars

Crank Brothers now offers XC/Racing and Freeride bars in aluminum or carbon fiber. There is nothing unusual or revolutionary about the bars, but the handlebar collection comes in a variety of different widths and rises to suit your tastes.

Interbike 2010 Las Vegas
Bars

Wheelsets

Crank Brothers tubeless ready wheelsets definitely catch your eye. The spokes connect to a vertical rib on the rim rather than a drilled hole through the rim wall, and the spoke meets an elongated nipple at a midpoint between the rim and the hub. The wheels come in a variety of colors and purposes, built for XC, 29er, Freeride, or DH.
