Pez-Test: TREK 5900
I was giggling like a school-girl… I’d just received the call from Dizzy Cycles – my local wrench-meisters and shop ‘o choice, advising me that it had arrived. The Trek 5900 that is. The same bike* that Trek provides to Lance and the US Postal boys! I giggled some more.
One of the best things about being a roadie is the level of refinement to which we can become accustomed. As geometries, technical and weight advantages become more standardized, it’s the details that start to make a bigger difference to satisfaction of ownership. The Trek 5900, 2003 model, delivers everything a refined roadie expects, but also a lot more.
Aesthetcially, the standout feature on this baby has got to be the frame – it’s a thing ‘o beauty. Sure it’s light, lightest in the world according to Trek, and with a full bike weight under 16 pounds (size: 54cm), who’s to argue? But the finish on the joints, the curves, the depth of that paint – makes ya say “ooooh baby”! Every joint is seamless, the smooth finish begs for a coat of wax lest it become dirty, and like a fine single malt, you must first behold the beauty, savour it, appreciate the hours of craftsmanship that created it. There’ll be lot’s of time for riding later.
Of course you’d expect this in a bike that is topline, and at around $4700US, this bike definitely hangs with some elite company.
OCLV FOR BEGINNERS I talked with John Riley from Trek, who gave me the insider info on Trek’s patented OCLV technology. “Optimal Compaction Low Void” – it’s how they combine carbon fibers and aluminum lugs to create a frame that is light, stiff, but subtle to ride. Quick production lesson for all you non-poindexters – carbon fiber is… just that, a bunch of fibers made from carbon, that get wrapped around/ into/ onto a frame mould. The whole batch gets glued together, kind of like working with papier-mache. Because you’re weaving many layers together to create a shape, there are inherently some air pockets, or VOIDS that exist betweem the layers of fibers. The pockets are weak points in the structure. OCLV is Trek’s way of squishing out the air-pockets to reduce the VOIDS, and make the frame stronger and stiffer. The head tube, down tube, top tube, and seat post all become one piece of seamlessly finished carbon art.
The OCLV technology is about 9 years old, now but Trek is not about to rest on their laurels. The bike is constantly being refined, with actual input from US Postal and Lance himself. In fact, Trek has two guys whose full-time job is to travel with US Postal as technical liasons – how’d you like that job!
Most importantly, it passed my own personal litmus test (you know you’ve all got one…) – does this product make me faster, or at least “feel” faster? The Trek scored full marks all around. Now, this was largely because I actually was going faster, but even rolling around my block I couldn’t wait to get ‘er on the open road – bring on the Spring winds, bring on the climbs – nothing can stop me now! But more on that in the next few weeks as we road test this bad boy to give you the full ride story.
So if you’re a serious racer looking for every weight advantage you can find, or someone with a fat wallet and an appreciation for rolling art, this bike is for you. Stay tuned for our full-on road test!
*NOTE: The bike we tested is the standard issue Trek 5900, and not exactly the same in all aspects as the Team issue bike ridden by US Postal. Some parts and components may vary as dictated by team sponsorshiop and rider preferences.

- USER REVIEWS
I bought a 9700 which, on the test ride (pre-riding at Rocky Hill Ranch), I dropped down a steep ravine and misjudged the landing badly enough that I broke the frame and bent the fork. Trek sent me two frames to choose from, and my choice I raced for 3 seasons and have just ridden it for the four years after, and I cannot compliment this frame enough but to say I bought the OCLV road bike. I still stop and check the back tire to see if it's flat, only to find 50psi and just a great feeling hardtail. I know they've 'improved' subsequent frames, but I wouldn't trade my warrior (or my six year old road frame) for any reason short of Trek telling me I had to.
Do not hesitate to buy one of these frames and ride and race it while smiling (if I were in the market, the STP 400 would be my top choice non-custom frame).

This bike is for riding, not looking at so stop moaning about stone chips. If you want it to stay in pristine condition, stick it in a display cabinet! If you are so worried about stone chips, either stick some ski top tape on the underside of the downtube and stop your complaining, or ignore it and enjoy this bike for what it is designed for - travelling XC very rapidly and enjoyably. After four years of totally trouble-free and reasonably aggressive riding, I have nothing but great things to say about this bike, other than the vast majority of riders are not good enough to really test it to its limits.
Best and lightest bike i have ever owned and that includes top end road bikes. have ridden the bike hard for the past 11 months almost everyday in rocky colorado. no signs of fatige or brakeage. stones do chip the clear coat and that is the only negitive that i see wrong with the frame. i started with the 96 9900 frame set and sl judy fork and built from there. the bike weights in at 20 lbs even with smoke tires that are not the lightest. everything is custom, ti and light on the bike. it rides and handles fantastic. I would not have any other frame right now. because of the lightness, it climbs like nothing i have ever ridden. stiff and easy to accelerate on the steep stuff. its been all over the colorado mountains and can handle just about anything. i use speed springs in the judy and that helped at lot in the suspension dept. because the bike is so light and seems to absorb shock, i donot think their is a need for fullsuspension if you have this frame. buy one if you can and build it. nothing is lighter! if you would like more info on the components on this 9900, e-mail me at [email protected] and i will be glad to share, and discuss the bike with other owners!
Light Stiff Cool Absorbs bumps did I mention it was Light
Cost Its a Trek (see review)
I love the bike. It is the best bike I've ever thrown a leg over. It is super fast, very responsive (almost too responsive sometimes), just an absolute joy to ride. Soaks up small bumps, climbs like a mule. Can't complain about one thing about the performance. In short, I love this bike and can't wait for the race season to start up. I bought this bike lightly used at a good price when compaired to close to $4K new from my LBS. The only thing was that the head tube had hit a rock (prev. owner) and they had been careless about hanging it on some type of rack and scrubbed some of the decals. Anyhow, I've read a lot of the reviews and seen everybody talk about the refurbishing program trek did on these bikes for @$300. I think that is a big chunk of money, but hey, it would really make my bike look trick and with the Spring racing season coming up, I might as well. So I trot down to my local Trek dealer (I have bought many things here, including a brand new trek 8000) and ask about the service. Sure they can do it, for $599 + tax. A new frame doesn't cost but $500 more. I can find clean used frames for $100 less. When I ask trek about this, they just give me the "local dealers discretion line." I guess it probably is the local dealer's fault in that they just don't want to deal with it. What I am curious about is what others have been told in regards to this. Please e-mail me and let me know. Thanks. Its just a shame when bike companies are good, they get big. When they get big, they can't handle problems themselves and have to delegate it to the local bike shops. The LBS either rock or suck depending on the individuals involved.
Litespeed Unicoi Raleigh M-200 highly modified Trek 8000 Bridgstone MB-3 Some old Giant
This bike is one sweet ride. Mad climbing speed, the OCLV frame lessens the little bumps, handles awesome, light and maneuverable.
The cable routing on the top tube is slightly inconvenient.
I would recommend this bike to anyone who doesn't want their rear end to get thrashed, but doesn't want a full suspension bike. My bike is approx. 22lbs. If you happened to overlook how well the bike handles, how well it absorbs the little bumps, or how light it is, then you would be left with one awesome looking bike, I think the way the top tube and head tube and all the other tubes connect just looks awesome. I am also selling the bike for reasons not related to how it performs, I just need the money. If you are interested in buying it, e-mail me.
Klein Attitude Pro (also a sweet ride).
Light and stable geomatry
Paint chipping needs maintenance
I just install my trek 9800 with 99 rockshox XC, you won't believe how sweet is the combination. Climbs at your will, falling is soft and controllable. Great frame, great fork. In fact, after installing fork, the geometry improves...
Marin team, trek 9500
Light as sin and climbs like a mountain goat.
$$$ but what the heck... XT brake are falling apart
Best ride i've ever been on. Went from an M2 (which i loved and beat the hell out of) to the 9900 (which i love and beat the hell out of). I can't imagine a bike that climbs better or is more fun in the singletrack. No frame problems at all.

Title : Active carbons as nanoporous materials for solving of environmental problems
However, up to now, the main carriers of catalytic additives have been mineral sorbents: silica gels, alumogels. This is obviously due to the fact that they consist of pure homogeneous components SiO2 and Al2O3, respectively. It is generally known that impurities, especially the ash elements, are catalytic poisons that reduce the effectiveness of the catalyst. Therefore, carbon sorbents with 5-15% by weight of ash elements in their composition are not used in the above mentioned technologies. However, in such an important field as a gas-mask technique, carbon sorbents (active carbons) are carriers of catalytic additives, providing effective protection of a person against any types of potent poisonous substances (PPS). In ESPE “JSC "Neorganika" there has been developed the technology of unique ashless spherical carbon carrier-catalysts by the method of liquid forming of furfural copolymers with subsequent gas-vapor activation, brand PAC. Active carbons PAC have 100% qualitative characteristics of the three main properties of carbon sorbents: strength - 100%, the proportion of sorbing pores in the pore space – 100%, purity - 100% (ash content is close to zero). A particularly outstanding feature of active PAC carbons is their uniquely high mechanical compressive strength of 740 ± 40 MPa, which is 3-7 times larger than that of such materials as granite, quartzite, electric coal, and is comparable to the value for cast iron - 400-1000 MPa. This allows the PAC to operate under severe conditions in moving and fluidized beds. Obviously, it is time to actively develop catalysts based on PAC sorbents for oil refining, petrochemicals, gas processing and various technologies of organic synthesis.

First refuelling for Russia’s Akademik Lomonosov floating NPP
The FNPP includes two KLT-40S reactor units. In such reactors, nuclear fuel is not replaced in the same way as in standard NPPs – partial replacement of fuel once every 12-18 months. Instead, once every few years the entire reactor core is replaced with and a full load of fresh fuel.
The KLT-40S reactor cores have a number of advantages compared with standard NPPs. For the first time, a cassette core was used, which made it possible to increase the fuel cycle to 3-3.5 years before refuelling, and also reduce by one and a half times the fuel component in the cost of the electricity produced. The operating experience of the FNPP provided the basis for the design of the new series of nuclear icebreaker reactors (series 22220). Currently, three such icebreakers have been launched.
The Akademik Lomonosov was connected to the power grid in December 2019, and put into commercial operation in May 2020.
Electricity generation from the FNPP at the end of 2023 amounted to 194 GWh. The population of Pevek is just over 4,000 people. However, the plant can potentially provide electricity to a city with a population of up to 100,000. The FNPP solved two problems. Firstly, it replaced the retiring capacities of the Bilibino Nuclear Power Plant, which has been operating since 1974, as well as the Chaunskaya Thermal Power Plant, which is more than 70 years old. It also supplies power to the main mining enterprises located in western Chukotka. In September, a 490 km 110 kilovolt power transmission line was put into operation connecting Pevek and Bilibino.

Our strongest, lightest carbon yet
OCLV Carbon is Trek’s patented carbon fibre process, the result of more than 25 years of experience building the world’s finest carbon fibre bicycles in Waterloo, Wisconsin, USA. Experience matters, especially when working with a material that holds seemingly endless possibilities but presents such unique challenges as carbon fibre. To understand the best technology, you have to build it, and we’ve been doing just that since 1991.
Why OCLV Carbon?
A well-built carbon frame dramatically reduces weight compared to metallic materials, while maintaining the strength and stiffness that high performance bicycles and their riders demand. This is where Trek’s pioneered and patented OCLV Carbon—an acronym for Optimum Compaction Low Void—process comes in. OCLV Carbon frames begin with the best material available. Trek has spent countless development hours perfecting the construction of a variety of weights and types of carbon (cloth, unidirectional, etc.). The OCLV process is best explained when broken down into two parts:
Optimum Compaction: Carbon is layered into a series of plies compacted to the ideal fibre-resin ratio. The process starts with cutting carbon fibre from large sheets to a specific shape which is then placed into a mould. A combination of heat and pressure then compresses the sheets of carbon into a carbon lug. This combination of heat and pressure is OCLV’s most essential and closely guarded equation. Low Void: Voids are the spaces that exist between the layers of carbon fibre that comprise a component or frame. Minimising these voids is the primary goal of quality carbon engineering, as more voids translates to reduced strength and durability of the composite material. OCLV Carbon exceeds aerospace standards regarding the number of voids in its material.
In addition to sizeable reductions in weight, the largest advantage of carbon fibre frames over another material are the limitless shapes that the material can be moulded into. Different shapes exhibit different strength, stiffness and aerodynamic properties. Trek utilises Finite Element Analysis, a comprehensive software simulation toolkit, to tell us exactly how different shapes will respond to different riders and riding surfaces. We utilise proven theories of fluid mechanics through Computational Fluid Dynamics in order to explore the aerodynamic properties of various designs. Our bikes are conceived with computer-generated designs, fluid-dynamically assessed and finite analysed, and the resulting shapes appear seamlessly machine-made. At the end of the day, these complex scientific investigations are applied in a hands-on, ground-up process that combines multiple moulds with a variety of carbon materials to result in a magnificently engineered and largely hand-built product.
Mountain biking is about pushing the limit of where your bike can take you. Riding on every conceivable surface in hostile conditions takes a toll on any material. To develop OCLV Mountain, Trek’s engineers developed a methodology borrowed from the aerospace industry to ensure our frames were up to the challenge: Retained Strength. The philosophy is simple and based around the single question of how durable a frame remains following impact. By employing different composite materials in unique layups specifically in typical high damage areas, Trek’s engineers have created frames that now retain their ability to bear load after an impact surpassing even their aluminium counterparts.
Taking durability to another level, Trek’s development team created Carbon Armor, a highly refined elastomeric designed to slow down and spread the distribution of a sharp impact to the frame. Carbon Armor essentially decreases the immediate impact of a rough hit the frame feels, leaving you feeling more confident than ever to go after that next drop.
Built to last
Trek builds bikes to last and we stand behind every one that we bears our name. Just as the first Trek hand-welded over forty years ago in a red barn, our first full carbon frame is still under warranty. All OCLV Carbon bicycles come with a limited lifetime warranty, because we believe that more people riding bikes is in everybody’s best interest.
