maybe i am on the wrong bike

i am 5'10'' and weight 270 ,i have a trek 7200 that i been riding for a year now .we did a 25 mile ride today and one thing i noticed was that the other riders with the 100% road biked took off from a stop and with in a few strokes they where almost out of site.. i under stand that they are in shape and been riding sometime but there was some guys there that where bid as me and they had the same "pick up and go" could it be the bike? or will my bike do the same thing there bike do but i need more time on it..?

you are on the right kind of bike. at 5'9", 210 lbs, my body would be uncomfortable with the road bike posture. i would have to get in shape for a leaner body and strong back & core muscles. comfort & healthy posture for an individual is most important to me.

yes, bikes with light frames & lighter wheels are going to be easier to accelerate. a road bike will also have a more aggressive geometry / set up to emphasize speed and less on comfort. but the most important aspect of a bike, imo, is still the engine. it's not like expensive bikes magically float forward. you still have to pedal hard and sweat it out to keep speed.

my suggestion is to stick with the hybrid because its upright position will probably be better for your back right now. if you want, lower the handlebars, get a longer stem, and move your seat back for an aggressive position. get in shape with this bike and then a year or two later move on to a road bike which will demand a posture you are now ready for.

oh, and if you have fat 35c tires, replace them with 28c slicks. that'll give you a boost for sure but it won't be as cushy a the 35c methinks.

From a stop to get up to speed that is pretty much all legs.
Does not really matter hybrid or road bike.
You have a nice bike, I would keep it and just keep riding.

The road bikes have the advantages of being lighter, that's about all that helps from a stop.

If you need to start off faster, there's only one way: Work on the engine. Give the engine more power and get it lighter.

F=ma, so a=F/m. Reduce m and increase F and a increases.

Reducing the weight of the rotating mass is the easiest way to have faster exceleration. Lighter tires and wheels. I think 700/32-35 has the best balance of comfort and speed.

Not an expert and I am not sure what a hybrid is but for 25 miles I can go under one hour or close with my 1984 Pinarello road bike but on my Specialized MTB with 1.5 inch smooth high pressure tires, not even close. Same engine--me--different bikes. One is a rocket ship and the other is a slug.

Each time to double your bicycle speed, for a given bicycle/rider combination, your drag quadruples. To go from 5MPH to 10MPH your energy output quadruples, and again to 20 and again to 40 which is why very few people can approach speeds without drafting over 30 MPH. The aerodynamic drag difference between sitting up high is greatly more than being tucked in the drops and the efficiency is improved as is your ability to bring your large upper leg muscles to fuller utilization.

Yes, it is partly the bike, partly fitness, partly correct technique which is enhanced by a good road bike set up correctly and riding down in the drops.
