Gevenalle CX Shifters

Gevenalle CX Shifters are the best change I’ve ever made to my bike. I don’t understand how STI brifters have any market share in the world where Gevenalle exist.

The left Gevenalle shifter is friction only. Shifting the front chain ring with friction is objectively superior to indexed. It allows me to make minute trim adjustments based on where I am in the rear cassette. This is especially useful with a triple crank (which I still run, because why wouldn’t I want more gears). With indexed shifting on a triple, you often end up with some gear combinations that cause rubbing front or rear if your cable tension is not perfectly dialed. Not so with friction. Just give it a slight nudge.

The right Gevenalle shifter can switch between indexed and friction shifting. I started out using it in indexed mode. After a few weeks of that I decided to give friction mode a whirl. I had never used friction shifting before. 9 months later, I’m still in friction mode. I do still think there is a place for indexed shifting in the rear, but I enjoy friction and have no current desire to switch back. (I haven’t even thought about cable tension all year!) I do, however, value the ability to switch between the two.

The real magic of the Gevenalle system is being able to jump the cassette between multiple gears with a single movement. An STI shifter may allow you to jump between 3 or 4 gears at once. With Gevenalle, you can dump the entire cassette in one smooth movement. That’s not something I do often, but I absolutely do dump or load about half the cassette at once. They market this as a feature for cyclocross racers, but it applies just as much to anyone who rides with other traffic.

This video is what helped sell me on the shifters when I was considering the purchase. It demonstrates the big cassette movements possible, as well as the ergonomics of using the system. Whether I push or pull the shift levers depends on where they are in relation to the brake lever. It takes a few minutes to get used to, but quickly becomes intuitive. As someone who spends most of the time on the hoods, I found that I didn’t need to change my hand position to actuate the shifters. Shifting from down in the drops is difficult or impossible, but if I’m down there it’s usually because I’m cruising down hill, already at mach 3, and not intending to shift anytime soon.

The Gevenalle shifters can be praised for their functionality. They are lightweight, simple, durable, and rebuildable. They don’t care if they’re caked in mud or bathed in the blood of your enemies or whatever. But they’re also just really fun. I shift a lot more frequently with these than I ever did with STI. They inspire a closer connection to the vehicle, perhaps similar to manually shifting an automobile. Having both visual and haptic feedback on where you are in your gears and how much move movement you have in either direction is fantastic. I refer to the front shifter as my hyperdrive switch. Anytime the rear shifter is moved all the way outboard and I flick the front all the way to the right I know shit is about to get real.

Many of the strengths of the Gevenalle shifters could also be claimed by bar-end or downtube setups, but Gevenalle allows you to keep all your in-flight controls in one place. I value being able to shift, brake, and flick my ding-ding all without moving my hands. I think this is especially important for city riding, when everything else on the road is actively trying to kill you. (And I still like using my bar-ends for mirrors, too.)

With Gevenalle, the brake cables run under the tape. Shift cables shoot out the side, like STI shifters of yore. When I installed them I made sure to cut my cables and housing long enough so that I had enough space to move the cables aside and shove my rando bag or bikepacking harness between them. It hasn’t been an issue. Back when STI shifters had this kind of cable routing, I used v-brake noodles to open up space for a bag. I haven’t found that necessary with Gevenalle shifters.

I’m not sure that I’d ever want to use a non-Gevenalle shift setup on a drop bar bike again.

A Better Phone Mount

When I purchased my first smart phone in 2013, I was motivated primarily by the promise of using Open Street Map for bicycle navigation. This does not require, but is greatly assisted by, a mounting system of some sort. I’ve tried a few over the years. Since 2015 I’ve used the Aduro U-Grip Plus Universal Bike Mount, which I think is an excellent design. It uses a ball and socket to provide complete adjustability. It secures the phone with a spring-loaded cradle and silicon band. Between the two, there’s no way the phone is falling out, unless the mount breaks. Unfortunately the whole thing is cheaply made of plastic. Earlier this month, mine finally broke.

After seven years, I feel I got my money’s worth out of the Aduro U-Grip, but when a tool like this fails I want to replace it with something better. Purchasing another of the same just resets the countdown to the next failure. Unfortunately, the bicycle phone mount market seems to be flooded with shit. Either they provide limited adjustability, or they require a special phone case. I have no interest in either. I was disappointed, and about to just order another Aduro U-Grip, until I happened upon Tackform. Their Enduro Mount was advertised for motorcycles, but I figured it ought to work on a real bike.

Tackform’s offering is similar in concept to Aduro’s, with a ball and socket providing complete adjustability, and phone security provided by a spring-loaded cradle and silicon band. But it raises durability to the extreme. I’ve had mine for just a few days. I am impressed.

The only plastic component is the wingnut used to lock the position of the cradle. Everything else is metal. The spring that operates the cradle is no joke. It is capable of operating as an improvised finger guillotine. Yet it is quick and easy to operate one-handed. Tackform includes a silicon band for further security, but in the packaging material they say that you really don’t need it. I believe they are correct. When it is installed in the cradle, I can lift the bike with the phone. The phone doesn’t move at all. It is difficult to imagine a scenario where the phone would escape.

The top of the cradle has a lip to prevent the phone from being pulled out straight up. The sides and bottom of the cradle are lined with a thin rubber to provide some protection to the phone. The outer edges of the cradle are quite sharp, which makes me somewhat nervous about a crash. I have no doubt that the mount would come through, and that the phone would still be secured in it, but my face might not fare so well if it comes into contact with the cradle. But, hey, that’s what eye pro is for.

The primary disadvantage to the Tackform Enduro is that the arm which connects the cradle to the bar mount is tightened with a single wingnut. To rotate the cradle from portrait to landscape mode, you have to loosen this wingnut, which also loosens the connection to the bar mount. So while the ball and socket connection gives you complete freedom to position the phone as you like, it’s the sort of thing where you need to figure out what position you want and then tighten the wingnut to lock it in. You won’t leave the wingnut loose enough to allow for adjustments while riding. With the Aduro U-Grip, the socket is part of the cradle, the ball is part of the bar mount, and I was always able to leave the nut which secures the two just loose enough that I could make minor in-flight positioning adjustments without compromising the security of the system. In practice, I have yet to find this limitation with the Tackform to be something I really care about. But if you want to be able to rotate between portrait and landscape modes without stopping and using two hands, look elsewhere.

The other disadvantage that some riders will identify is weight. I didn’t weigh the components, but what you’re dealing with here is basically just a chunk of aluminum. I imagine the whole system is somewhere around 6 oz, which is significantly more than the plastic competitors. If you have much spandex in your wardrobe, you won’t be happy with Tackform. But my bike is carefully built for what I see as the ideal compromise between performance and durability, and the Tackform mount makes the cut.

Beyond the durability of the system, what endures me to Tackform is that their products really are systems. They are not just selling a few application-specific packages, but have whole series of components. It’s like a grown-up Lego set. I appreciate knowing that I could replace an individual component, or buy just the piece I need to expand the mount’s applicability to different vehicles or environments.

None of Tackform’s products are cheap, but they claim that their products are designed to last a lifetime. After the first 100 miles on this mount, I believe that statement will prove accurate. I suspect that the slab-format pocket terminal will be phased out and become irrelevant well before the Tackform Enduro will fail.

The mount is manufactured in the country of Taiwan, so get yours before China expands its beachfront property.

Titanium Fuel Transport

Last January I bought a pack of generic stretch silicone lids. My hope was that one of the sizes in the pack would fit my 16 year old Snow Peak Trek 700. One did. This turns the mug into an excellent fuel transport container. It’s kind of a poor man’s Vargo BOT 700.

I have filled the mug with water, installed the silicone lid, flipped it upside down, and left it standing overnight. In the morning there were no leaks. I’m still hesitant to actually transport liquids using the lid. Mostly because the silicone is extremely thin, and I’m sure it is going to tear eventually. But if you’re into cold soaking food on the trail, and don’t want to carry a dedicated jar, I think this could be an attractive option. For leftovers, it’s perfect.

The lids I bought are no longer available, but there is certainly no shortage of equivalents floating around on Amazon-AliExpress-eBay. Based on the number search results, my impression is that China is drowning in silicone stretch lids.

Every Day Pliers

I carry Fix It Sticks for screwing and small Westcott scissors for snipping. Since learning about them last year on Jerking the Trigger, I’ve carried Knipex 87-00-100 Cobra Pliers for gripping. There are times when a classic multitool, like a Leatherman, is preferable, but I find this selection is more functional for most of my mobile tool needs.

I measure the baby Knipex pliers at an overall length of 103 millimeters and a mass of 60 grams. They are an excellent purchase.

A Better Kanteen Lid

My favorite lid for standard mouth Klean Kanteen bottles is the Topoko Straw Lid B. It’s a simple flip-top straw lid. The only thing that makes it special is that the mouthpiece is covered when closed. It seems like a common sense concept, but so many sport lids have no provision for some sort of mud guard.

Other than that, there’s not much to say about the lid. It is completely leak-proof when closed. It is easy to operate one handed. It comes with two straws that can be cut to length. One is stiff and the other is bendy. I’ve found no functional difference between the two.

I have these lids installed on both the bottles I use on a daily basis – the 27 oz that I carry on my bike, and the 40 oz I use at home.

I did break one of the lids by accidentally dropping the bottle from about 4 feet onto concrete. It broke where the carry loop connects to the base. The lid still sealed and functioned properly. I only use the loop for pulling the bottle out of a cage or pouch, but I still purchased a replacement (and another spare) immediately.

The new lids I received were slightly different from the old ones. The bit that covers the mouthpiece is clear instead of black, and the edge of it is flush with the edge of the lid. On the old model, the black cover was a couple millimeters proud of the edge of the lid, which provided more purchase when grabbing the piece to flip it open. The older design seems superior, but I haven’t actually noticed a practical disadvantage with the new one. I can still easily and reliably flip the lid open, even with a gloved finger. (That is, however, with light gloves – the older design may have more of an advantage with heavy winter gloves.)

I’ve only used the lids on Klean Kanteen bottles. I use these bottles for water. I don’t know if there are any special considerations that would make the lids less than ideal for hot beverages.

I’ve used every iteration of Klean Kanteen’s Sport Cap since I bought my first bottle from them in 2005. They’ve all left something to be desired. The Topoko lid is a superior solution.

Cablz Eyewear Retention

I’ve previously mentioned my fondness for Rudy Rydon eyewear (particularly with the photochromic laser red lenses). One of the benefits of the Rydons is the adjustability of the temples and the nose pad, which allow for a secure, custom fit. This makes added retention via a strap unnecessary for securing the Rydons on the face, yet I’ve come to appreciate having a retainer attached simply because it allows me to drop the eyewear around my neck when I don’t need it. This offers more security than pushing them up onto the crown of my head or hanging them over the edge of my shirt or pocket, without requiring the hassle of putting them away in a pack.

For this application I’ve come to like the Cablz Zipz Adjustable Eyewear Retainer. I use the 12 inch version. These are made of a coated, stainless steel wire. When you’re wearing the eyewear, the wire sits up off the neck so you don’t feel the retainer at all. When you’re hanging it around your neck, it is thin and light enough that you soon forget it is there (this is also a result of the lightness of the Rydons, of course). The zip allows the length of the retainer to adjust from about 6 inches to 12 inches. At the smallest setting this keeps the Rydons tight on my face, but since that is not what I’m looking for I keep it adjusted about half way. At roughly 9 inches in length, I find that I can easily don and doff the eyewear, and that they sit at a comfortable position on my chest when I’m hanging them around my neck. The “universal” silicon ends of the retainer grab securely on the Rydon temples.

Cablz isn’t the only company to offer this style of retainer.

The Croakies ARC Endless is the same basic idea. I bought one to try out, but found it to be inferior. The silicon ends are significantly thicker and less comfortable behind the ear. I could bend the Rydon temples to account for this extra thickness, but I appreciate that the Cablz retainer requires no adjustment of the eyewear. With the Croakies, the pieces you grab to tighten the retainer are quite small. You’re adjusting the retainer blind by reaching behind your head, so the haptics are important. I found the Croakies difficult to use when wearing gloves. The Cablz adjustment pieces are large enough to be easy to use whether gloved or gloveless.

The equivalent from Chums is the Adjustable Orbiter. It only adjusts from 10 inches to 15.5 inches, which is too large for my needs, so I didn’t buy one to try.

I recommend the retainer from Cablz. It provides a simple but helpful augmentation to my eyeball protection system.

Zensah Leg Compression

I purchased a pair of Zensah Compression Leg Sleeves in 2008 after reading about them at MilitaryMorons. This was when minimalist running was beginning to take off – Born to Run was published the following year – and I found that the sleeves ended up being a valuable part of my transition to less supportive footwear.

The story I was sold in various wilderness medicine courses was that compression aided recovery because it constricted the blood vessels, raising the percentage of oxygen delivered to the area, which in turn speeds muscle regrowth. I understand there is some debate about whether this explanation is accurate but, whatever the reason for it, there seems to be no debate that compression aids recovery and performance.

I still use my 12 year old pair of Zensah sleeves. They’re not a piece of equipment I reach for frequently, but they’re invaluable when I do use them. If I’ve been pushing myself on runs – or, in the Before Times, if I had a hard training session at the boxing gym – there’s nothing better than the immediate comfort I get when sliding them on. Because I don’t use them often, sometimes I’ll forgot that they’re buried in the bottom of my sock drawer and I’ll go a couple days with discomfort in my calves that I can’t get out with a roller or massage ball.

Prior to buying the Zensah sleeves, I would occasionally accomplish the same thing with 3M Vetrap. It works, and is worth having around for splinting (the self-adhesive property makes it superior to the classic ACE elastic bandage), but wrapping and getting the tension just-so is more of a hassle than just sliding on the sleeves. Vetrap is also not as comfortable as Zensah’s material, which is both breathable and moisture wicking.

How Not to Die

Last year I read How Not to Die by Dr. Michael Greger on the recommendation of Hundred Rabbits.

The book is divided into two parts. The first part addresses common killers and how they can be mitigated, prevented or reversed through nutrition. The second part of the book covers specific food groups and gives guidelines for their regular consumption.

The book is meticulously researched, with every claim backed up by real, peer-reviewed science. When reading it, it felt like every other sentence had a citation. It’s unlikely that the average reader could actually go through each of the cited studies to confirm that the conclusions presented in the book are an accurate representation of the paper, or if they’ve been skewed to better fit Dr. Greger’s message.

The book grew out of NutritionFacts.org, a non-profit organization started by Dr. Greger with the goal of reading and understanding as much of the published science on nutrition and health as possible, and presenting the results as dietary guidelines actionable for normal people. (Unfortunately the website focuses primarily on video dissemination, which for me is an ineffective means of information transmission. I prefer plain text. Hence the book.)

Dr. Greger is largely opposed to consuming meat. He eschews terms like “vegetarianism”, instead preferring to advocate for what he calls an evidence-based diet centered on whole-food, plant based nutrition. I like to consume flesh, do not intend to stop, and think the consumption of it does provide important nutritional value (a point on which the doctor does acquiesce). Many of his warnings about flesh eating are less about the nutritional value of the meat itself and more about the cleanliness of the production and preparation environment. However, if you can look past the anti-meat tendencies and the possible biases in which type of research is reported on, there is still a lot of very good data in the book. It’s one of the best owner’s manuals for the body that I have read.
