The Lightest Road Bike with Disc Brakes!

Unleash the Beast!

For a decade now, we here at Rodriguez have been known for building some of the lightest bikes on the road. The amazing thing about these bikes is that they are made of good ol’ American steel! Well actually, they are made of the New American Steel. In 2006 we introduced our 13.5 pound Rodriguez Outlaw. That led to mass retirements of Trek Madone’s, Cervelo R3’s, Specialized Tarmac’s, and many many other overseas-made carbon frames. We love the look on people’s faces when they lift the Outlaw for the first time. Especially if they rode in on something they thought was ‘really light’.

Well, now we’d like to introduce something else equally spectacular. The Outlaw has a new cousin equipped with disc brakes, the Rodriguez Bandito. It took some time, and some planning to get this bike down to it’s fly-weight of just 15.9 pounds, but we’ve done it. The lightest disc brake bikes that we’ve been able to verify weight on are at least 2 pounds heavier than the Bandito.

First up: 32c Tires

Now here’s an idea. One of the benefits to disc brakes on a road bike is that the brake caliper no longer limits your tire width. So, if the frame and fork are designed properly, you can put wide tires on your bike. Unfortunately, race bike manufacturers don’t realize that most ‘everyday’ riders would like this ability, and design their forks and frames for the same skinny tires that you could run with caliper brakes:-( We ask “where’s the fun in that?!”

The Bandito is the first ultra-light disc brake road bike designed for use with wide tires. As a matter of fact, we even did the weigh in with 32c tires on the bike. You can run up to 35c tires on this bike. We see the ability to run wide tires as the most important advantage to road disc brakes. Otherwise, why pay the weight penalty?

Next features: Lighter, more comfortable and more durable than your carbon bike

Now you won’t have to compromise weight, ride quality, comfort, or durability to own the sweetest ride in the pack. The Banditio comes with our lifetime warranty, just like all of our steel bikes (most carbon bikes have just 5 year limited warranties). Steel has a well deserved reputation as the smoothest riding material, but also is thought of as heavy:-( This is because most of us owned heavy steel bikes back in the 1970’s, and we associated the ‘heft’ with the frame material. We loved the ride, but were willing to sacrifice that smooth ride to save a few pounds on aluminum or carbon fiber. Well, steel has evolved, and now we can make a Rodriguez from steel that’s lighter than it’s carbon or aluminum counterparts. Some of you are probably ready to email us and schedule a test ride…right? Others out there, I know will be reading this and thinking “Bull Sh#$%” right? Well, read on then. I’ll explain a few things that will help you understand how we can pull this off.

Use your head:
Let’s talk about head tubes and head sets. This is the part of the bike where the fork is attached, and the bearings are referred to as the head set. Originally, carbon fiber bikes used the same sized head tubes and ISO head sets as titanium, aluminum and steel bikes. This part of the frame is under more stress, and carbon frames began to fail at this point. So, manufacturers began to ‘beef up’ this part of their carbon frames. Unlike aluminum, titanium and steel frames, it turns out carbon frames needed more material in this area in order to have the strength needed. To fit these bigger head tubes, bigger, non-standard head sets were used, and sometimes a proprietary fork. The issues of non-standard, or proprietary parts are many, but one thing is for sure. The bigger head tubes and head sets, and proprietary forks may have made the frame weight lower, but added weight to the full bike when built.

Bottoms up:
Now, let’s talk about bottom brackets. This is the part of your frame that holds the bearings for your cranks. Needless to say, this is also also weak point on a carbon bike. It’s a point of great stress on any frame. To fit the ultra-light, standard ISO bottom brackets that are used in steel, aluminum and titanium bikes, the carbon guys had to glue in a steel or aluminum shell so they could put threads in it. This added weight to a carbon frame. This was also a weak point as eventually the glue failed. To solve the problem, the carbon guys again abandoned the long held ISO standards, and adapted one of several different non-standards. Again, the frame had to be ‘beefed up’ and a heavier bottom bracket had to be used.

Let’s compare:
This brings us to an interesting point. Wether intentional or not, these evolutions artificially make a carbon frame seem lighter than it is. If one weighs just the carbon frame, without it’s required heavier bottom bracket and head set, the frame can be a little lighter than our steel Bandito. So a published frame weight is not the only thing to look at. If one weighs the carbon frame with it’s fork, required head set, and required bottom bracket, the result will be quite different. You see, an ultra-light Rodriguez steel frame, you can still use ultra-light ISO standard parts. This means that you can run much lighter head sets and bottom brackets, and in some cases forks. The result is very similar weights, or often, a lighter combined weight for the Rodriguez ultra-light.

So, no more weighing just the frame. You need to weigh the entire bike, or at least the frame with it’s bottom bracket, head set and fork to get a real comparison. If you do that, you’ll find the secret behind the Rodriguez ultra-light steel bikes like the new Bandito.

Added weight for no reason:
When designing the Bandito, we weighed a larger head tube and head set like the carbon bikes run. A lot of steel bike manufacturers run these, but I have no idea why. For instance, the weight difference between an ISO head tube set up and a 44mm head tube was just shy of 1/2 of a pound! On a steel bike, that’s completely unnecessary added weight, as a steel frame is strong enough without all of that ‘beef’.

Then, add to that the larger bottom brackets. The added weight again would be wasted on a steel frame, but none-the-less, a lot of steel bike builders use them.

If a steel bike has these larger head tubes, head sets, bottom bracket shells, and bottom brackets, it is a pretty heavy frame, and a really heavy bike. But, we don’t don’t use that stuff. I would put our ultra-light steel bikes up against any fly-weight on the market of any material.

In closing I’d like to say, if you love really light bikes, and you haven’t ridden a custom, American hand-made Rodriguez ultra-light, DO before you spend money on a carbon frame mass-produced overseas. If you already own a carbon bike, we challenge you to come in for a ride…but be careful…most who do wind up on a Rodriguez.
