Felt Z1, Part I

When Felt Bicycles came back from the brink of extinction a few years back I took note. Jim Felt had been a motorcycle race mechanic for a great many big names in motocross, names like Johnny “O-show” O’Mara. He was a good fabricator and had a creative mind.

And then he got interested in triathlon.

It turns out, some of the riders he worked with were starting to do tri’s to stay fit. He started doing them as well and noticed a funny thing. He couldn’t get the triathlon bars low enough to get a truly flat back while riding a properly sized frame.

So he built a few bike frames. They were notable for quick handling and very, very short head tubes. Head tubes that in some instances measured less than 10cm. Riding a Felt was the only way to guarantee your position was as aerodynamic as possible, relative to the time. And the proof was, as they say, in the puddin’. Big names, names like Paula Newby-Fraser began to win on Felts.

The broadest sections of the top and down tubes are located at the top and bottom of the tubes, respectively.

In 1996 I spent a week on a Felt. Manufactured by Answer Products in Valencia, Calif., through a licensing agreement with Jim Felt, the frame was TIG-welded from 7000-series aluminum, which needed no heat-treating, thereby dropping manufacturing costs dramatically and increasing the chances that the frame was properly aligned. Back then, Answer employed a number of manufacturing staffers who were part of the ‘90s aerospace diaspora. At the time, I lived in Valencia and rode on a regular basis with a half dozen of them. A few of them told me that if they couldn’t make $60k working in aerospace, then working on bikes was at least cool.

The aerospace bit wouldn’t be important were it not for the fact that their experience made the bikes damn good. The welding was exquisite and alignment superior to any other aluminum bike I’d seen at the time.

Back to that Felt I rode in ’96. This was the same bike Chris Horner won Athens Twilight on and a career making stage at the Tour DuPont in a two-up sprint against the more experienced U.S. Postal rider, Nate Reiss; ’96 would prove to be Reiss’ last season with Postal. Oops.

The bike I rode was unlike any bike I had ever ridden. It was unusually lively for aluminum, as stiff as any Klein I had ever ridden and carried exquisite grace of a filet knife. It scared the shit out of me.

Then Answer went through what we’ll term a transition. In 2000 the new management decided to get out of the business of road bikes and cut Felt loose.

Felt’s carbon fiber frames are called modular monocoque because they are molded in several sections: the main triangle, a rear wishbone and then the chainstays.

It turns out this was the best thing that could have happened to Jim Felt and his brand.

Bill Duehring, a former VP with GT and all-around industry lifer, had partnered with Michael Müllmann, the owner of one of Europe’s most successful distributors, Sport Import, and the two wanted to start a bike company. The three decided to team up and together they forged a formidable partnership. Felt was known for his ideas about frame and tubing design. Duehring was known for impeccably spec’d bikes at great price points and Müllmann had access to capital and distribution channels.

It was this incarnation of Felt that loaned me a road bike to review when I published Asphalt. Ron Peterson, the editor who reviewed the bike, lauded it for the feel of the butted Easton Scandium tubing and the handling which he adored for crit racing.

At the next Interbike the company showed off its first carbon bike, the F1. A quick look at the tube shapes told me it wasn’t an open-mold design with their decals. It was their own design, engineered in-house. The F1 was essentially the company’s long-admired road bike geometry in carbon form.

In 2007 the company introduced a new road bike model, the Z1. Like the F, the Z was offered at a number of price points, but the Z1 was notable because it used the same blend of ultra-high, high and intermediate modulus carbon fibers as the F1. The similarities ended there.

The Z-series bikes are grand touring bikes. Compared to the F-series bikes, they are built around longer head tubes (not hard to do), slacker head tube angles and more fork rake. They also get longer chainstays. The slackish head tube angle, generous fork rake and longish chainstays gave the bike a longer wheelbase while maintaining the same weight distribution between front and rear wheels as the F-series bikes.

It’s easy to be cynical and just say Felt was aping what Specialized did with the Roubaix, but there are a few differences worth noting. First, the bottom bracket is a bit higher on the Z than on the Roubaix. Next, the Z doesn’t use the Zertz vibration dampers—Felt’s head of engineering, Jeff Soucek, says he doesn’t believe they do anything to help the ride quality of the bike; I’ve argued the point with him, but that’s a different story. Third, as mentioned previously, Felt specs exactly the same blend of carbon fibers in the Z1 that goes into the flagship F1 model. My 56cm Z1 frame weighed in at 906 grams (g).

Lots of companies will talk a good sub-kilo game, but far fewer are doing it than you might think. I watched a 52cm Trek Madone—minus seat mast—tip the scales at 1133g. I haven’t had a chance to weigh a Specialized Roubaix SL2, which would be the frame analogous to the Z1, but when I asked a Specialized representative what it weighed I was told “around a kilo.” I take that to mean north of a kilo, because if it was consistently less than a kilo, that feature would be touted like the cup size of a porn star, I expect.

Let’s talk competitive models for a moment. I have to volunteer that I have some trouble taking a bike company seriously if they don’t offer a grand touring model. Now, in the case of a company such as Seven Cycles that builds bikes to suit the rider, there’s no need to offer a specific model for one geometry, but production-oriented companies are another story. Trek’s got the Pilot, Cannondale the Synapse, Cervelo the RS, Bianchi the Infinito and Giant the Defy. Interestingly, Scott claims to offer two “performance” oriented models “more relaxed geometry. Those two models, the CR1 and the Speedster are more relaxed in marketing copy alone. They have the same BB drop (6.7cm) same chainstay length (40.5cm) and same head tube angle (73 degrees for the large size) as their racing model, the Addict. Indeed, the CR1 became “relaxed” when they introduced the Addict. Perhaps they were referring to the fact that the head tube is a massive 2cm longer on the CR1 and Speedster than on the Addict. Whatever.

The vast majority of these bikes feature a watered-down carbon fiber blend (compared to flagship models) and a component spec that says century riders won’t notice an extra three or four pounds. Anyone who thinks only fast racer types will spend big bucks on a bike have completely misread the bike market. Completely.

    I recently purchased a Felt on the recommendation of an LBS after years of swearing by Specialized. After a couple of weeks of riding, I think it’s safe for me to say I won’t be switching back soon.

    Looking forward to part II

    Good points, all of them. I have always regarded Felt much the same, definitely no knock off brand w/their own decals pasted on a chinese frame. Whereas the F series and Z series are good for what they are made of, my interest has recently been on what their latest high end modulus carbon frames have done. They are really bending the curve of innovation in carbon-frames.

      Wow. It’s amazing how some folks think a stem flipped up is just “wrong.” I don’t understand why folks don’t place fit and position ahead of looks. I love a good looking bike, but if I’m not comfortable and can’t ride as fast as I’m able, what’s the point? In that photo there’s a 7cm difference between the saddle height and the bar height. I could kinda understand the flipped-up stem criticism if it resulted in a bar that is higher than the saddle.

      In fact, I’ve ridden this bike with the stem in both positions. To ride with the stem down, I have to be willing to give up some power on the climbs, though I’m very aero on the flats and I feel a bit more confident descending. I also need to be in pretty prime form; it takes a lot of flexibility to ride in the drops when the bar is almost 10cm lower than the saddle.

    What the HELL is that thing.
    Is this serious? please tell me your joking with those pictures and set-up. The bike looks to be significantly too small for the rider.

    Even though I read way too much about bikes – I always dismissed Felt bikes as kind of carbon clone kind of company. I was wrong, thanks for setting that straight.

    Angling up stems? On some bikes it looks okay, on others – just plain wrong. If it’s more comfortable – who cares – as long as it works for that rider.

    I would agree though, if things are that out of sorts, maybe the frame is a bit small.
