2011 Orbea Aqua accelerates slower than 2005 Trek 1000

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

2011 Orbea Aqua accelerates slower than 2005 Trek 1000

Hi, thank you very much for letting me participate in the forum. I begun road biking on a 2005 Trek 1000, I still use this bike to get around town, it was my one and only untill I recently purchased the Aqua. I noticed the Trek to seem to accelerate a bit faster, it has an old triple sora crank with an bontrager race light in the back, never I have changed the BB. The Orbea has the Shimano wh-r500 wheels and an FSA gossamer double compact. The Orbea is only about 3 weeks old, does it need to be broken in longer? Are the hubs too tight? BB? Is the Bontrager Race light that more superior of a wheel? Or is it in my head? I'm stumped and look forward to reading your ideas. Thanks.

Um, is this based on your feeling alone or do you have some concrete numbers to back it up as well? Don't mean to be a jerk, sometimes speed just "feels" different, depending on the geometry of the bike.

Switch wheels and see if it makes a difference.

What he said. But it's probably in your head. A lot of people expect a new bike to be like night and day from their old beater. When this doesn't happen, they are disappointed.

the new bike could have misadjusted brakes that are dragging. otherwise, there aren't any good physical reasons for this and it's probably fit, comfort or familiarity.

It's probably not the old bike that is faster but likely the old rider.

How much riding have you done this season to date?

Lift each wheel off the ground and spin it. You probably won't see it slow down any faster than the older bike's wheel, which would rule out bad bearings or brake rubbing.

What tires are on the two bikes? Good tires can make a (small) difference. And air pressure matters, too.

why does no one mention fit? you could just be setup for a more efficient stroke on the trek.

this poster is driving towards fit. that's why he wants to see them.

It has been great to get so many perspectives. One of the more obvious ideas, I impulsively overlooked, was to switch wheels or to spin each wheel separately to observe any resistance. I noticed very little difference. It may be noted that my new wheels (Shimano R-500) have quickly become out of true. I took them both for a quick test spin and equated my observation to not much more than feeling. I apologize for the misunderstanding I will try to be conscientious the next time I post. Looking back, relating to short distances, I have felt faster on old steel bikes than newer machines, illusions of external stimuli. Anyways Im going to stop blabbering now, I appreciate anyone who posted, I did learn something.

unless the the gear inches on both bikes are identical, it don't think a perceived acceleration is comparable.

think of accelerating a v-8 mustang from a standing start in first gear, then again starting in third gear. not comparable.

the human body is no mustang. there are plenty of gears available on both bikes to where the OP surely is picking comparable gears. it's not like one bike has a 46/36 cyclocross crankset and the other 53/39 standard. even if that were the case, there's not a lot of difference in the midrange gears.

My first thought is that the gearing is different, and that's what you're noticing.

+1

I was used to compact crankset, & compact CX crankset before I moved to a standard crankset on my newest bike.
It took me a few rides for me to get a feel for the standard gears.
