4/2 I'm trying to get less drag on my hybrid bike so that I can
catch up to people. I've heard from this guy that wind is
about 80% of the drag at 30km/h, and that by crouching down
you cut wind resistance by about 1/3. Short of getting a real
road bike which is stiff and uncomfortable, is it "wrong" to
get a drop down handlebar for a hybrid bike?
\_ If you want a faster bike that's more comfortable than a
conventional upright road bike, then try a recumbent.
\_ Right now, I can catch up to tom for a short period of time
before he ditches everyone else. If I get a recumbent, will
I be able to catch up to him for a slightly longer period
of time? -outa shape guy
\_ Modern recumbents (highracers such as the Bacchetta Aero, or
lowracers such as the Velokraft VK2) are more aerodynamic than
modern uprights. This means that for a given power input, the
recumbent will produce a higher speed. This has been
confirmed in wind tunnels. This doesn't necessarily mean
that you'll be faster on a recumbent, or that it will be
easier for you to catch a particular rider. When placed on
a more efficient bike, some riders have a tendency to slack
off and expend less energy to maintain their customary speed.
Some upright riders tend to expend more energy to avoid
letting a recumbent catch up with them.
\_ Alright I'm interested, where can I try one for free
and how expensive are they? Ebay has them for as low as
$800, which still is a lot. Also how much do fairings
help aerodynamically? I need to be able to catch up
to people without having to work too hard. Thanks.
\_ I ride a very heavy mountain bike with a lot of crap
hanging off the sides. When I see one of those road
bike hosers with a 2000 dollar bike and a lycra outfit
covered in corporate logos for no good reason(because
it's some fat dude who's obsiously not on a cycling
team), I'll bust ass to stay ahead of him no matter what,
just on principle.
\_ That may be so for one or two rich asses but you
can't possibly beat every single one of the hard
core roadsters. I bet you can't beat tom.
\_ I'm positive I couldn't beat a hardcore racer type
like tom. But I'm also pretty sure a guy like that
wouldn't be making a big deal out of passing an
obvious commuter with two bags over his shoulder
and a heavy bike. If someone minds their own
business, I'll mind mine, but some of these fat
yuppie roadbikers seem to think they're the shit
because they can pass me on their ultralight toys.
I feel the need to remind them in the most phyical
possible way that spending money
does not substitute for riding every day.
\_ Uh, I'm not a racer type, and I'm not particularly
fast among racer types. Although I have dropped
people on $2K Lemonds on my Schwinn. -tom
\_ You seem to have a lot of hate for people
who can afford bigger toys than you. Cheer up!
\_ Uhh, no. I could probably afford a more
expensive bike than most of those people,
and pay cash. I hate stupid fat yuppie
poseurs. While many roadbikers are clearly
good poeple and great athletes, I would argue
that the vast majority of fat stupid yuppie
poseurs on bikes are on road bikes.
\_ On a long ride, an upright road bike should be more comfortable
than a hybrid, because the hybrid's upright seating position puts
a greater strain on your lower back. The riding position of an
upright road bike shifts about 35% of your body weight off your
spine (and onto the handlebars). Are your comments about road
bikes based on actual experience on long rides? |
