Trek STP 5200 ?Shanks23

Do you remember the 2002 Trek STP 400? If not, go check out the 2002 bike index at

Basically, STP = Soft Tail Pro. The superlight racer with just enough rear suspension to take the edge off.

The unreal lightness of an OCLV Carbon frame coupled with the benefits of a rear-suspension.

The pivotless Leaf Spring Design rear-suspension replaces the monostay with a rear shock to soak up hits without the weight and energy-sapping float of a swingarm. This design is made possible by the strength and inherent compliance of OCLV Carbon chain stays.

Tunable rear suspension: A custom Rock Shox SID Race rear shock, with positive and negative air chambers and external damping, allows you to fine tune your level of comfort and control - up to 1.25"/35mm of rear wheel travel.

So if they can apply this to their OCLV Mountain frames, what's stopping them to do the same to their OCLV Road frames? It's like what they say "The superlight racer with just enough rear suspension to take the edge off." 250g to take the edge off won't kill you.

Here's what it could look like.

Let me know what you think. KHS Bikes actually make such a bike... Perhaps Trek should join the race.
no one would buy it-nmandy02

It's a solution looking for a problem,TJeanloz

OCLV road frames are designed for, well, road riding. There is no need for a dual suspension road bike. I'm convinced that the people who bought the Serotta Hors Categorie just did so to prove that they could buy the most overpriced bike ever. How many times have you been riding on the road and thought that some suspension would really help?
Soft Tail isn't a dual suspension road bikeShanks23

I currently own a Trek 2300 and have been positionned by professionals. Still at the end of the day, after a ride of over 125+ KM, my back can be soar. I usually get 3000+ KM a year.

A soft tail would just take the edge off of things. It's not a dual suspension road bike by the way, it's a soft tail road bike, much like the following known manufacturers build:

It's also more commonly used in the mountain bike industry of course:

And you only add 250G to the bike's weight. You simply need to replace the monostay with a good light weight rear shock that can be locked when you need to climb or sprint away.

The KHS CX100 is OK, but I would be more interested if it was using better components. So if companies already build these, then we know people buy them, especially if one of them only makes soft tails. The question is, how can you tell it's not good if you never road one?
Serotta HC ain't so bad.Spiderman

Granted, the Serotta HC is a little bit ugly, and pretty expensive but it rides incredibly well. Suspension was originally designed with the idea of keeping the wheel in contact with the ground more. Rather than skipping over logs, rocks etc, the wheel would be able to track up one side of the rock and down the other, increasing handling, drivetrain effeciency etc. The HC has that same concept in mind. Obviously you aren't riding over roots and logs on a road bike but the rear end allows the rear wheel to stick to the ground better. Any crit racing, any riding on crappy roads (pavement cracks, ruts) any technical descent the rear triangle is handling the minute road fluctuations, which a lot of times you don't even notice, rather than the tire/wheel absorbing the shock, compromising stability/handling.

Unfortunately, it just so happens that the rear end also does yield a very plush ride so everyone understood it as a "comfort bike" which in reality it is not. And Shanks, if you want a cross bike so badly, try looking at the HC as a cross bike. Very light, and will still make for a very smooth off road ride.

Also take a look at it from the idea that Serotta is thinking very out of the box in their design, something that not a lot of companies are doing. They are doing it in materials only (not that isn't part of the design of a bike) but there is more to it than just materials.
That KHS is a Cross bike...not a road bikebiknben

That KHS is not intended for road use. It's a cross frame. Carbon provides plenty of cushion for the road. If you think this design doesn't sap energy you have another thing coming.

If you just gotta have it then get a suspension seat post.
