This time every year, while the trade shows are rolling along, I find myself freshly amazed at how little companies seem to know about their product–or at least how little they’re willing to share with the end users.

Take Shimano’s site. The new SLX components are fantastics–a standout group among some excellent groups–but you’d be hard pressed to learn that from the company’s site. In fact, you’d be hard pressed to learn anything.

What’s the bolt-pattern on those chainrings? Blank space. Are those crank arms hollow? Tough to say. Average weight? Another blank space. Here’s the exact features spec from their page:

Model Number FC-M675
Series SLX
Crank Construction Hollowtech II Technology
Cassette Compatibility 10
Chain Compatibility HG-X 10-speed
4-Arm Chainrings Yes
Cahainring Sizes
Bolt Circle Diameter
Crank Arm Length 170,175mm
Crank Arms
Outer Chainring 40T/38T
Middle Chainring
Inner Chainring 28T/26T
Chainring Bolts & Nuts Yes
Chain Guard No
Chaincase Compatible No
Bottom Bracket SM-BB70 SM-BB71-41A
E-type FD Compatible
Chain Line 48.8mm
BB Shell Width –
Average Weight

Seriously guys, if you don’t know any of this data, and you created the damn thing, what’s the consumer supposed to do? You’re Shimano–biggest and most powerful bike component company in the universe–and you’re populating your consumer-facing site content with shit from a half-ass ERP system, typos and all?

Personally, I’m disappointed it’s not “Chaincase Compatible.”

But hey, that’s SLX. Nobody buys that shit aftermarket, right? And the bike companies all choose groups and components based on price. Now, the top-of-the-line: that’s where we get the solid data.

Consider the first sentence of the new 11-speed Dura-Ace cassette description currently on Shimano’s site:

“Rider-tuned means Dura-Ace works the way you want it.”

Read over that sentence again and tell me how Shimano’s site content is any better than Innova’s (my current gold standard):

(Josh at work found that on Friday, and instantly it made everyone who saw it a better person.)

And before SRAM can back out of the room quietly, let’s learn something about their PC 1051 10-speed chain.

“SRAM continues to innovate the chains that continue to win races around the world. The new PC 1051 10 speed PowerChain™ featuring the PowerLock connecting link provides smooth, precise shifting and weight savings.”

To their credit, SRAM at least has some separate specs with information that’s borderline useful, but most descriptions read as bullshitty and useless as the PC 1051–except the ones that say even less, like the 1031 chain:

“Simply stronger. The PC 1031 chain benefits from new design changes for better performance.”

Oh, well OK then.

But the James Joyce Stream-of-unconsciousness Award goes to the Force cranket.

“Competition-focused technology for the serious set, wherelight weight, strength, and durability come together. The SRAM Force crankset is offered in a BB30 option and, just like SRAM RED, the BB30 crankset is 10% stiffer, 20% lighter, and provides 300% more ankle clearance than the GXP version. Thanks to the unidirectional carbon structure, both GXP and BB30 crankset versions deliver a sleeker and race-proven design.”

Um, what’s inside the crank arms? Are they hollow? What’s the bolt pattern? While I don’t doubt the importance of putting ankle clearance into mathematical terms no human could possibly comprehend, I have to wonder if we could possibly find out whether or not this crankset comes with a bottom bracket.

Online or local, there will always be a need for bike shops, the beat reporters for the bike industry, asking the tough questions that have no answers.

Why don’t companies like Shimano and SRAM spend a tiny fraction of their marketing budget on hiring someone capable of writing copy that makes sense? Tough to say. Why does Innova prefer backwards apostrophes?

Why do you ask so many questions? Do yourself.

While I’ve been adjusting to a new life in Portland and spending every minute outside of work searching for a new home, some interesting things have been afoot back in the bike industry. Most notably, evidence of what basically amounts to a merger between Shimano and Fox continues to grow. I’d first written about the “unique electricity” between the two companies back on March 2nd, but at this point, they might as well have exchanged class rings.

Regardless of what any of us think of completely and utterly wired bicycles, the intersection of Di2 and Fox’s CTD suspension system should pretty much be considered the point at which the two companies effectively become one–at least as far as competitors are concerned. Given all the suspension patents being held by Shimano and the more recent evidence surfacing on Geoff Kabush’s Scott, the partnership is definitely trying to shake off SRAM. The most interesting part of all of this might now become SRAM’s response. In the past, SRAM has proven particularly effective at using Shimano’s innovations against them, turning the barrel of things like “Dual-control” right back at them and pulling the trigger. For all the grumbling, electronics have been receiving a pretty warm welcome from consumers, while SRAM holds to an emphasis on ultralight mechanical designs and simplicity. Shimano remains the 800lb gorilla of the bike business, but both companies are on pretty solid ground now, and both are capable of innovating.

Given that SRAM seems to prefer to grow by acquisition, if they were to go after electronics, it’s tough to imagine any clear targets, but more unique companies like Factor are certainly doing some interesting and very different things with integrated electronics.

One way or another, it seems like the next few years are going to be pretty interesting to watch.

It seems I haven’t been the only one to notice Shimano’s steadily accumulating arsenal of game-changing patents lately. Matt Wiebe’s new article in Bicycle Retailer draws attention to the industry behemoth’s patent portfolio, which dwarfs the competition. Wiebe writes that Shimano “is moving into areas of development—dirt suspension, hydraulic rim brakes, dropper seatposts and electric integration—that could shake up the market if the technology makes it into production.” Absolutely. And you don’t build an empire on your production capabilities by applying for patents for stuff you never intend to make. By all indications, Shimano is about to deliver their second major industry shakeup, and things are about to get rough for SRAM.

Or maybe not.

Much is constantly made of the relationship between component manufacturers and bike companies. The Bicycle Retailer article rightly points out the market share SRAM had been gaining in bundling suspension and components for OE spec on bikes, and the conspicuous silence from Shimano regarding this. “A survey of suspension engineers, who declined to go on record, said Shimano has the technology to make competitive forks,” writes Wiebe, “but none thought the company was setting up to enter the market. At the same time, however, they wonder how long Shimano can stand on the sidelines as SRAM’s RockShox suspension line enables it to offer product managers seductive pricing on component and suspension packages.”

The article goes on to point out that Shimano’s continuing absence from the suspension market continues to offer “a lifeline for Fox, Manitou, Marzocchi, SR Suntour and others,” which is true, except that one of those brands is clearly not like the others. Shimano doesn’t share patents with Marzocchi, Manitou or any also-ran suspension companies the way they do with Fox. The recent high-profile move of the Santa Cruz Syndicate team from SRAM to “Shimano and Fox,” combined with some pretty clear writing on the patent walls makes one thing pretty clear.

Shimano is going to buy Fox.

That is, if they even need to. Plenty of business mechanics to compute there, and clearly both companies are already benefiting from a very close partnership that might not require actually tying the corporate knot, but the writing is clearly on the wall.

Manitou and Marzocchi? Yes, they’re doomed. What’s left of them, at least. But SRAM? I don’t think so.

Continued and even strengthening relationships between Fox and Shimano will certainly not be good for SRAM, but SRAM has what it takes to survive the assault, and stands to benefit from the attrition that’d take place in the suspension market. Already borderline non-existent in the OE market, Manitou and Marzocchi’s potential total extinction stands to benefit SRAM’s RockShox division, a company with a far wider assortment of suspension products across a wide price range–much wider than Fox. A full assault by the combined Shimano and Fox forces would make what’s been happening over the past decade offical: nobody would be left but SRAM.

And somehow, White Brothers. Have to hand it to those scrappy little guys.

SRAM’s suspension products still need both brand work and innovation before they can truly rival the industry reputation and near rear suspension monopoly that is Fox, but SRAM has made tremendous headway in paying attention to the end user. When Shimano notoriously “integrated” your shifting and braking on mountain bikes, SRAM very specifically did not. SRAM has also led the way in 2×10 mountain drivetrains, a “by the people, for the people” kind of revolution. In both cases, SRAM’s marketing did an outstanding job of delivering the message: “We know what you want, and we’re building it for you.” They used Shimano’s enormous weight against them, getting the big guys off balance in the eyes of the public. Behind the scenes, this was a blip on Shimano’s bottom line, but SRAM set up shop inside that market inflection point and carved out a huge name for themselves.

It’s going to come down to electronics. If Di2 is any indication, Shimano may have already won the war, but it’s also possible that we’ll see a backlash to electronics among riders out there. SRAM has already drawn a line in the sand when it comes to road groups. Want to save a pound and a half? You know where find us. Adoption of electronics on mountain bikes could be more complicated–especially if Shimano plans to have a battery operating everything from your shifting to your suspension damping. Picture the entrance of a Shimano/Fox electronically controlled suspension fork onto the market with a price tag over $1000. How would that be received? How would it be promoted?

Interesting stuff. One thing is certain, though. If I were SRAM’s marketing department these days, I’d be putting a lot of effort into grassroots racing support and features the average rider can clearly appreciate–and I wouldn’t be pushing the panic button just yet. People still like alternatives. If SRAM can maintain their image as the best alternative, that’s good enough. It’s like the old “outrunning a bear” thing: SRAM doesn’t have to be faster than Shimano/Fox; they just have to be faster than all those delicious little companies who are much slower than they are. What looks like a vicious war between Shimano and SRAM might turn out to be pretty painless for both companies, but completely devastating to everybody else.

Patently Oblivious: Weird Bike Stuff is Out There

Few things are better on a rainy morning than settling in with a full pot of coffee and some time to cruise freaky patents. Sure, I’m supposed to pretend facing a rainy morning while racing a 24-hour event–or better still, wrenching one–is the more honorable, Klingon sort of path to joy, but, having done that, I call bullshit. Nice to be warm today, and I like looking at the future. The strange, strange future. While, for me, nothing will compare to the old days of Interbike, when small companies could still afford to booth up on the ground floor and show off their bizarre wares, sorting through upcoming patents is as close as it gets. Will these things see the light of day? Tough to say, but here are a few reasons to hope the Mayans are wrong.

About all I can say to this is: “wow.” If you think you’ve seen everything possible in the world of bicycle suspension, you need to say hello to a kind of four-bar with bars that criss-cross in an “x” pattern, which seems to be what’s going on here.



Pretty straightforward here. So staightforward, in fact, that I can’t really believe this was approved. If blending seat stays into your top tube’s a crime the Handmade Show is going to look like Occupy Oakland.


Like everyone else, I’ve been kicking Specialized in the nuts for a while now over their recent marketing self-immolation stunt against Volagi, so it’s nice to point out some positive–if somewhat bizarre–things they have up their big red sleeves.

Tough to say where they’re going with a sort of bloated seat tube as suspension system, but I love the initiative. Goofy envelope-pushing stuff like this is the good side of Specialized.

While this smacks of notorious “lawyer tabs” on forks, I have to admit it’s a simple way to keep your handlebars from completely flying out of your stem.

Um, but . . . so this solves a problem? Is there a reason we all need to be concerned about this, guys? At first glance, the safety clip on this stem design seems like it’d only come into play if your stem’s faceplate exploded off or something. Might have to up my life insurance and/or read this one over carefully.


Nice and practical, SRAM’s design for a front derailleur with a really compact, multi-cable-pull-friendly actuation arm. I figured I’d include this because it’s nice to see front derailleurs–if one must still use them–being shrunken as much as possible. This makes frame designers very happy.

Have a question about the what’s left of the future? Go look at some patent, or feel free to ask me. I love this stuff.

Speed Compatibility

Question:
Compatibility Question for Mr. Manic… I understand that SRAM and Shimano derailluers are not interchangeable because of the amount of cable the shifters pull, and the resulting movement of the parallelogram linkage in the derailleur, right? But what about using a 10-speed SRAM shifter with a 9-speed SRAM rear derailleur? Mountain doubles make so much more sense to me, but I don’t want to spend my hard-earned cash for a new derailleur if the old one can be made to work.

Answer:
Right on. If you’re looking to simplify your life, a double chainring configuration is a good start. Only three things in this world are worse than a mountain bike with a triple chainring crankset: cannibalism, Russel Brand, and a road bike with a triple (in that order). Unfortunately, you can’t substitute a 9-speed SRAM rear derailleur for a 10-speed model. I know it seems like you should be able to do this, but, according to SRAM, the “Exact Actuation” leverage ratio found on all their 10-speed rear derailleurs is actually different from the “1:1” ratio used on 9-speed derailleurs, so trying to mix those up would lead to the same kind of shifting problems you’d encounter if mixing SRAM shifters and Shimano rear derailleurs. Even though the shifter is the brains of the operation, telling the rear derailleur how much to move for each shift, the leverage ratio on the rear derailleur ultimately determines how to translate those increments, and the 9-speed derailleurs don’t use the same ratio as the 10-speeds.

If making the move to 10-speed all at once is a bit much (now that rear derailleurs cost more than many bikes), consider going with a 9-speed double ring configuration. Most 11-34t 9-speed cassettes offer a pretty broad range, and it turns out companies like Blackspire offer chainrings purported to work with both 9 and 10-speed systems and available in hip, dualie configurations, like a 26-tooth inner ring and a 38-tooth outer. Once your ship comes in, you could buy a 10-speed rear derailleur, rear shifter, chain, and cassette, and become what historians call “contemporary.”

Size Matters

Question:
I need to replace my rear derailleur. What are the differences between the short/medium/long cage? Does the length of the cage matter that much?

Answer:
The easy answer is, if you have to ask, get a long cage. A long cage will work in every situation. I’m one of those “teach a guy to fish, so he quits asking me to give him fish” types, though, so let’s impart us some knowledge.

Understanding the differences in cage length means understanding both things a rear derailleur does. We all know a rear derailleur moves the chain in and out from one cog to another, but the other, equally important thing a derailleur does is move forward and back, taking up chain slack that varies as you change gears. Imagine your geared bike as a singlespeed with a bunch of gears in the back, but no rear derailleur. Suppose you had a chain that was the exact perfect length to wrap around your 32-tooth ring up front and your 34-tooth cog in the back without being too tight, or too saggy. Great. Now leave the chain on the same ring up front, but move it to the 11-tooth in the back. Saggy, isn’t it? If only there was a way have the same length chain adjust itself for smaller or larger gears. Luckily, a bunch of people in the 1800s had the same problem, and realized some sort of spring tension on the chain was the answer. The bigger the difference between the sizes of your gears, the more chain you need your derailleur to be able to take up. The ability of a rear derailleur to handle a range of chain lengths is referred to as the derailleur’s “chain wrap capacity.” You can calculate your chain wrap capacity by subtracting the number of teeth on your largest front chainring from the number of teeth on your smallest front chainring, doing the same with the gears on your rear cassette, then adding the two values. So necessary chain wrap capacity on a bike with a 44-tooth big ring, 22-tooth small ring, and 11-34-tooth cassette, would work out like this:

(44-22) + (34-11) = 45

The longer the cage of a rear derailleur, the more flappy chain it can pull tight, so the wider variance you can have between gears. Sometimes a manufacturer will tell you the chain wrap capacity of their rear derailleur, but the bottom line is you should always be sure you have enough chain to reach every gear combination—even the crossed-up ones you shouldn’t use, but might shift into accidentally. For most mountain triples, that amount of chain requires a long cage rear derailleur, and those work just fine.

So why do people try to use any shorter cages? In theory, a medium or short cage derailleur may shift just a fraction better because a shorter cage equals a stiffer cage, and they’re slightly less vulnerable to getting smote by rocks and the local flora, so experimentation is fine, provided you’re careful. In fact, most configurations will accept a medium cage rear derailleur, but only if chain length is set up carefully, and you error on the side of leaving more chain than you think you need. It also helps if you get rid of your biggest or smallest cog to lower that required chain wrap number. For most people, the added risk and configuration challenges aren’t worth the time, making the long cage the go-to option.
