Ibis introduces the Hakkalugi Disc

Cyclocross

Hakkalügi Disc
The Hakkalügi, while technically a cyclocross bike, has always been much more. We’ve ridden it on road centuries, on epic dirt rides surrounded by others on mountain bikes and in local underground races. Some of our most popular outings are ones that involve a bit of road and a bit of dirt.

We’ve raced it in cyclocross races, and a number of them at that. The original Hakkalügi is what Don Myrah rode to a UCI Masters World Championship (45-49) in 2012. He, along with Barb Howe and Danny Summerhill have ridden ‘Lugis to National Championship victories. In other words, it’s a legitimate cross bike as well as the most versatile bike you’ll have in your quiver. You do have a quiver, don’t you?

Disc-O-Lügi
The all-new from the contact patch up Hakkalügi Disc, as you might have guessed by now, has disc brakes. Another update is a change to a tapered steerer fork, which adds a tremendous amount of front-end precision, enabling shutter-free, predictable braking. The Hakkalügi disc has new geometry in every one of its 6 sizes from 47cm to 61cm. We’ve also switched over to a press fit BB, saving weight and adding rigidity. The lay-up is based on the tried and true Hakkalügi lay-up, resulting in a phenomenally strong frame that weighs under 1150g even in the largest size. In fact, it takes 900+ lbs of force at the front axle to break the down tube, more than some full suspension mountain bikes. Despite its extremely low weight, the rest of the frame is also exceptionally strong and does not have any known weak spots. What that means is that you can ride it for years without fear of pesky problems like chain stay or bottom bracket cracks. Our experience with the prior Hak is that the frame will last until someone crashes (hard) or drives into the garage with the bikes on the roof (doh!).

We’ve built in generous tire clearance. A 38C with good sized knobs will fit, and still have a lot of wiggle room for mud, out of true wheels, and fenders. And that’s just on the rear. The front ENVE composite fork has even more room.

Do I Really Need Disc Brakes?
Yes. Rim brakes have greatly diminished braking power in the wet. Would you accept driving a car that required you to think ahead a couple hundred feet before the brakes started working in wet conditions? No. Since cross bikes get ridden in inclement weather quite often, you are faced with this same dilemma. With the advent of disc brakes, that’s not true any more. You can bring the speed down faster with the discs vs rim brakes and as mentioned, there’s no fork shudder. It also takes lower brake lever force, so you are less prone to hand and arm fatigue. This becomes a noticeable advantage on fast bumpy descents.

No more being kept down by ‘the man’
We’ve been anxiously awaiting the day when discs become acceptable on cross bikes, and when the UCI relaxed their prohibition of disc brakes back in _____ we got to work on the newest version of the “Lugi”. With the rule changes, we also knew that the brake manufacturers would be working hard on new hardware for us (and you). The days of drop bar levers with integrated hydraulic cylinders aren’t quite upon us yet, but fortunately we have a lot of excellent braking options. Our two parts picks (Shimano Ultegra or SRAM Rival) come stock with the brand new and excellent Shimano BR-CX75 mechanical disc brakes. While these brakes are the best yet mechanical brakes, hydraulic brakes are superior. We are anxiously awaiting SRAM and Shimano’s inevitable announcement of hydraulic disc compatible drop bar levers. For now, there are options now from both TRP (Parabox 2012) and from 324 Labs (Brake Adapter System), the 324 we have tested extensively. Formula recently showed a hydraulic brake drop bar lever with Di2 shifting integration.

In other words, we have excellent braking options now, with more on the horizon.
