About the Visualiser

Our virtual mechanic is pretty fast. He's also sometimes kind of lazy. He'll swap out frame colors and show you your drivetrain upgrades but he says it takes too long to change brakes and things. He's doing his best but please excuse any irregularities you may notice...

We also really, really recommend that you use the latest version of your favourite web browser. Definitely not IE7 or earlier. Basically, if things look weird here try upgrading your browser.

Hey, Don't click me!

Tranny

Ibis bike underline

The Ibis Tranny may look like a simple yet beautiful carbon fiber hardtail but look closer and you will see so much more. The Tranny is one of the most versatile frames that has ever been produced – easily switching between geared and singlespeed and travelbike guises. Being made of high modulus carbon the Tranny is of course lightweight but we think you will agree that a frame weight of around 3.1 lbs is pretty special, especially considering how strong it is!

Stiff, light, tough, geared, singlespeed, travelbike – a Tranny can do it all.

Reviews / Awards

It’s a carbon fiber hardtail.
It’s a geared bike.
It’s a single speed.
It’s a travel bike.
It’s all of the above.

It’s the Ibis Tranny.

People used to ask us "When are you going to make a hardtail?", "When are you going to make a single speed?", "When are you going to make a super light XC race bike?", "When are you going to make a travel bike?". We answered all of them with the production of the Tranny.

First and foremost, the Ibis Tranny is a strong and lightweight monocoque carbon fiber hardtail. And a lightweight, laterally stiff, vertically compliant one at that. The Tranny goes far beyond being just a hardtail, as a result of some unique features. Several of the features came out of the removable, adjustable-length, chainstay. This means you can transform it from a single speed to a geared bike to a travel bike in a matter of minutes.

How Do We Do It?

Take a close peek at the section behind the bottom bracket. There's some hidden equipment down there we call the "Slot Machine". It's not really a machine, but it does have a slot that makes it adjustable. That allows us to lengthen the chainstays, so we can make this thing into a bona fide single speed. It's lighter than an eccentric bottom bracket, and cleaner than a chain tensioner. Look at our little animation of the Slot Machine in action under the gallery tab. Look at the first two pictures. One bolt cinches the whole thing up.
As an added bonus, that same box of magic along with the curious little bolt up along the wishbone allows you to take the whole rear end off of the bike. Two bolts and it's in two pieces. Why would you want to do that? Easier to travel with my friends, and also possible to fly with this thing in a travel case and not pay the exorbitant fees the airlines like to charge us to carry our bikes.

Not much of a Weight Penalty

The Tranny frame weighs about 1350g, which in America translates to about 3 lbs. With the WTF group, the complete bike weight is about 19 lbs. Not bad for such a versatile machine.

Shave Some Weight

Dress this beast up as a Single Speed and lose another pound plus. Get really freaky and put a rigid front fork on there and you're down in the road bike weight realm.

We've been tossing around a lot of other ways to dress up your Tranny as well. One of our favorites is to use a rigid 700c disc brake front fork, a set of Mavic SpeedCity wheels and see how low you can go. 16 lbs or so? Or leave the suspension fork on there and try the SpeedCitys that way. Note, with SpeedCity wheels, you're limited to approximately a 700x25c or 700x28c. In other words, no you won't be able to make it into 29er.

NEW! Nifty Details

Of the various details we've been sorting out with the Tranny, two are pretty cool and perhaps even unprecedented. Both are a result of the tranny's transformation from a single speed to a geared bike. Check out the detailed shots above. We've designed the tranny to have removable gear cable stops. We figure you'll always want brakes, but sometimes you might not want gears. The two cable stops for the rear derailleur are removable. And so are the derailleur cable stops found on the top tube. Pretty nifty if we do say so. Clean even. Another extraneous item when you are single speeding is a derailleur hanger. And in the spirit of the single speed mantra "Less Gears, More Beers", you'll find the Tranny has a nice little bottle opener integrated into the single speed version. Note to those of you under the legal drinking age or many of you Utahans the mantra can also read "Less Gears, More Root Beers".

Colors

The Tranny is available in three colors. The first is a matte clear, based on our extremely popular matte finish found on the MojoSL. It's not rubberized, just a flat matte clear. Looks really good. For those of you who want to make more of a statement, we have two really good options. First, a Granny Smith Apple metallic Green. Yum. And then there's Copper Metallic. You can see both above.
