In my opinion, as far as I can tell, most of the hybrids have mountain bike
gearing, or close to it.
Thus you run out of gears trying to upshift as you go faster on those easy
downhill stretches anyway.
In this case going faster than about 15 to 17mph (depending on the bike) has
you pedaling like crazy, so you start coasting instead.
I wound up riding a bunch of different bikes, from Specialized, Cannondale,
Trek, etc. I sorta liked the Cannondale BadBoy the most (Trek's 7200-7300
were really nice too) but it had the Mountain Bike gearing, which sucks on
the road, and it cost a lot more than I expected, especially since I would
have to modify it anyway. Then you have the problem of everyone wanting to
steal it too.
I am older, big, fat guy, plus I have a bad back as well. Also I have
problems with my hands geting too numb after a while, detracting from the
overall fun of it.
I wound up buying a Raliegh SC30 comfort bike amazingly enough, to use over
my Diamondback MTB just for some of those reasons. Higher riding position,
less pressure on my hands causing numbness. Suspension and a larger seat for
more comfortabe riding. All those other features looked like too much
marketing hype to me (carbon fibre, zertz inserts, ultra light frames). The
vast majority of bikes are made for people that are 5'5" in size and 140
pounds tops, thus a ultralight frame will likely break on me.
It also has a fully adjustable stem, so I can adjust the handlebars most
anyway want to, and it is easy to replace with a straight bar as well.
Unfortunately I thought the SC-30 had something like the Shimano Megarange
cassette (as their internet specs stated it) with 11 to 34 teeth sprockets,
instead, in reality, it has the more common sprockets 14 to 34 teeth. So it
tops out at about 16 mph on those downhill stretches, but since my old MTB
tops out at about 12-13mph this is still a improvement.
I plan to replace the rear cassette with a 11-34 Megarange model, that 11
tooth sprocket would let me go up to about 20mph or a bit over. A regular
road bike with a 12 tooth rear sprocket (and a 52 tooth front chainring)
would go about 21mph+ so this change should work well.
I want to replace the front big chainring with a 52 tooth one later as well,
but this is going to be harder as I have to change out the entire crank as
well, since the inexpensive crank and chainring are all one piece all spot
welded together. The quick change wheels are nice as I can switch out for
the road slicks quickly too with another full set of wheels too. That is
another thing to consider if you like the disc brakes.
Anyway, it is more cost effective for me to upgrade the inexpensive Raleigh
SC30 than to get a fancy more expensive bike and still have to upgrade it as
well.
Right now it looks like all the town commuter like hybrid bikes all have
mountain bike gearing, when they should haven something more like both road
and mountain bike gearing. Currently the SC30 allows me to use the middle
chainring now for flat stretches whereas on the mountain bike I had to use
the largest chainring.
I would seriously try a test ride where you can determine how well the bikes
do on those slight downhill stretches and on those long flat streches.
Also get down there on your knees and count the sprocket teeth and see what
they really have there, the specs may be in error.

Quoted message said:Last year I rode a bike for the first time in 25 years. I bought a
Raleigh M-80 as an impulse purchase while buying my daughter a bike for
her birthday.
It was a surprise to me that I really got into riding. From June to
November I put about 900 miles on it (Catseye computer stopped working in
Oct). I ride paved roads only. My typical ride is 15 miles, I coast much
of the first half and have to get the elevation back after the turnaround.
So I get a pretty good workout. On weekends I like to punch that out to a
25 mile ride, time permitting. I had slicks put on the Raleigh in
September, which reduced road drag considerably.
This year I'd like to ratchet my riding up a notch, and will purchase a
new bike to do so.
I think I want a hybrid bike, as I'm 5'5" and 225 lbs (FAT). So that
whole "upright riding position" thing will really be a benefit for me.
The LBS I've worked with is recommending a Trek Pilot 2.1:
http://www2.trekbikes.com/en/Bikes/Road/Performance_Road/Pilot/Pilot_21/index.php
They won't have these in stock for two weeks, so I haven't had a chance to
spin one around the parking lot. They will mount an extra set of hand
brakes on the horizontal part of the bar and probably replace the hb riser
with a more upright one, as they did on my Raleigh.
Fit will be a primary consideration in my purchase, as will build quality
and component set. My budget will be limited to $1500.
Anyone have opinions on this bike, and suggestions for competing bikes in
my price range?
Thanks
