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 have been asking 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 travel bike?", "When are you going to make a 29er?". We've got answer for all of you. The answer is NOW. Well, except the 29er folk who are going to need to wait.

Briefly:
First and foremost, the 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, resulting in some unique features. The features are a result 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. 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 1250g, which in America translates to about 2.75 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?
