The Bosberg
More and more companies are moving to more and more exotic technology and exaggerated tube shapes in an effort to differentiate themselves from their competition. But most of these extra acronyms and curves don't do anything to actually make the frame stiffer or lighter or nicer to ride. Likewise, aero road frames may be faster in the wind tunnel, but they just just can't offer as comfortable a ride. That's why we believe the best way to create a solid, balanced road frame is through simply shaped, large volume carbon tubes that are created with the highest compaction possible. As a result, the Bosberg is straightforward, simple and beefy. Sure there are plenty of great bikes out there, but few tie together performance, beauty and price quite as well as a Bosberg. It will also make you roughly 240% more attractive and 312% more intimidating.
Named after the final climb in the Ronde Van Vlaanderen, the 2011 Bosberg is light, stiff and well-balanced. It's made from the highest quality, high-modulus Toray uni-directional carbon made to our standards. It features carbon dropouts and an integrated seat mast to save weight, a BB30 bottom bracket and massive chain stays for power transfer, and a tapered 1.125″ to 1.25″ head tube for precise handling. It is designed to be a good all-around race rig: as comfortable on day-long rides is it is confident in hectic criteriums. Take it down a high-speed descent and you'll really see where the Bosberg is a true stand-out; its rigid front and rear end allow it to trace a perfect arc around turns.
All this beef, and yet weight weenies can be be happy too: Frames with uncut seat mast weigh between 920g-1150g (Size XS - XXL), the fork with uncut steerer weighs a scant 350g. Bolt on nice components and a pair of racing wheels and it easily approaches 13 pounds.
NOTE: 2012 Bosbergs are designed for 24mm max tire diameter. Some 25mm clincher tires won't fit.

Reviews
“My Bosberg has me in a state of bliss I have not felt since I my first glimpse of a Playboy centerfold.”
“I bought a Bosberg.
Prior to ordering it, I thought: "Well, at least it will look cool when I line up at crits or in the rain."
You have to understand that I never intended the Bosberg would become my race bike. I own a very sexy, very stiff and extremely light Cervelo R3 SL. I know this because when I asked why a frame would cost $4000, I was told "it is very stiff, very light and very sexy." Or at least I was told some version of that.
You can believe that even at less than half the price of the Cervelo, the special lady friend was not a fan of another bike to simply look cool with friends. After all, I spent months telling her why the R3 SL was worth every penny.
I raced the Cervelo for a year and loved just about every minute. I won more than my share of stage races, road races and crits. Hype or otherwise, when Bicycling Magazine said the "R3 SL was one of the top bikes ever made," it was an astonishing understatement.
My first ride on the Bosberg was a mid week morning spin to dial in the saddle height and I remember knowing the BB30 and rear triangle were no joke. I was used to the Cervelo's whippy feeling pedal dancing. The Bosberg did not have any wasted movement. I was not lifting the rear tire off the ground and I never felt like I was trying to stay in front of the bike. I pushed a pedal down and the bike went forward. Pretty simple.
Nonetheless, I did not intend to race it at that weekend's Callville Bay Classic. It was just too soon. But a last minute derailleur problem forced my hand. And a back injury forced me to race seated and required help to get out of bed each day of the race. Despite the pain, I felt completely at home on the Bosberg and found myself capable of responding to successive attacks seated. Based on my honorary degrees in bicycle engineering and triathlete bashing from Bike U (a subsidiary of Bicycle.net.), I figure my seated power delivery was from the serious bottom bracket and no b.s. chainstays. And unlike a triathlete, my kit has sleeves.
I raced it again, and again, and again. The next thing I knew I was scavenging pedals from the R3 SL for the girlfriend's first clipless experience.
A few weeks ago, I entered a notorious Northern California "climber's race." I took the Cervelo off the garage wall. The need to replace the Bosberg's chain clinched the decision, but in the back of my mind, I paid for Sram Red (the Bosberg is outfitted with Force) and dammit I was going to use it. Somehow it was a chance for the aging vet to show he could still come out of the pen if needed. Instead of Eckersley of 1988, I got a 1999 Doc Gooden.
After nearly 80 miles of searching for a rhythm and trying to find a line, I realized why the "top bike ever made" was hanging on my wall just days ago.
There was something about my position on the Cervelo that left me unstable on a decent. In fact, a year ago I DNFed two races after a yet-to-be-diagnosed vibration left me unable to keep up on descents. The Bosberg's tapered headtube let me carve a line around descending radius turns without much effort or thought.
I also found myself wondering what happened to my direct power transfer. I mean the Cervelo was more than sexy, it was also stiff...at least that is what Bicycle magazine told me.
In the end I missed the reliability of the Bosberg, the knowledge that no pedal stroke would be wasted and that the bike was going where I wanted it to go.
I am a reasonable person. I hardly act on a whim. In fact, the Commonwealth of Pennsylvania has outlawed my whims in an effort to preserve the integrity of the Pennsylvania-Dutch farm daughters. So over the holiday, I made a list of pros and cons between the Cervelo and Bosberg.
Cervelo won in one category. It is indeed light. I've remedied that by moving my Red grouppo to the Bosberg. Don't get me wrong, both frames have been on a scale, and the R3 SL is lighter, but at what cost? In my opinion, fighting to keep the rear tire on the ground during an attack or over rough road isn't an advantage.
I have a race machine now, its my Bosberg.
Not coincidentally, I'm selling a R3 SL frame set, let me know if your interested. I'll even send you the Bicycle Magazine review, it will give you comfort that you got a good deal even though the bike consistently under preforms. Trust me, I used to race it.”
“My Bosberg has gotten me laid three times this week. And I'm married!”
“Over the years I have ridden and raced on Specialized, Lemond, Cannondale and Colnago. The Bosberg is as stiff and faster to accelerate as any of the others, on the flats or in the hills it is easy to ride. Where the Ritte bike leaves these others in the dust is handling. I have never been on a bike that corners as well as the Bosberg. Since I got my Bosberg I haven't touched my other bikes.”
“After riding the Ritte Bosberg yesterday for it’s maiden voyage, I was at first reluctant to believe that it could in any shape or form match the climbing prowess and road dampening of my Cervelo R3 SL or the stiffness and quick high speed steering stability of my Canondale System6. I was wrong. I was blown away by its combination of excellent ride quality without sacrificing any power when I needed it. Sharp cornering at high speeds was delightful and added confidence building around each turn. The feeling of road stability and controlled responsiveness was a combined experience I had never had before in a bike. I just wanted to go faster. This bike seems to be the perfect road race, climbing, and criterium power cornering machine. I can confidently say I think I will no longer need any of my other bikes. One can only imagine how good the future Ritte TT frame will be!”
