Looking for a truthful answer

[cindysue]

also, just out of curiousity - what size wsd do you ride at 5'10??

56 - Orbea Dama Race

[cindysue]

I make sure to always carry my own tubes and a patch kit, as it is less likely that anyone else will have a tube that size to loan. annie

Great point Annie! 650 is a rare breed - please be prepared for anything!

The linear velocity of the wheel is the product of the wheel radius and the angular velocity (rpm's) of the wheel.

speed = wheel radius X revolutions per minute

So far cranks turning the same rpm with the same gearing, the 700c wheel will be traveling at a higher speed than the 650c wheel.

This can be overcome with gearing, which is what bikefriday does. But the root for needing to overcome this begins with the wheel size.

I'm 4'11" and ride a 47cm Trek WSD 2200 with 650cc wheels. I LOVE the bike - it handles beautifully and is incredible responsive.
I have never noticed a problem with speed / keeping up; in fact, I feel more comfortable & confident on the bike than I ever did on the 43cm with 700 cc bike I used to ride (an engineering marvel if there ever was one).

I ride a 46cm Aegis Swift with 650c wheels and I have no trouble keeping up with other gals in our club (except for the A-paced riders; I'm not in their league, but that's not about the bike but the engine). I find that the 650 wheels accelerate fast, and the other nice thing about them is that they are lighter than 700s! Like Annie notes, I do have to carry my own tube and patch kit, but I've been lucky enough never to have a flat on this bike so haven't had to use it. I can't imagine riding a bike with 700c wheels at my size (5'2"), but I've never tried it so can't really compare - other than a Terry with a 700c in back, 24" in front, which was more of a pain b/c of the two different tire sizes, and it was a heavier bike, so I was slower on it.

I guess I just don't see what the big deal about 650c wheels is; this topic comes up again and again here, and I've heard so many gals, even shorties like me, say they just didn't want to ride 650c-wheeled bikes. I don't give a flying fig about what anyone else thinks (but I get tons of compliments on my pretty Aegis, even from the guys); I want to ride a bike that fits me and is not too much bike for me to handle - I even have a 20"-wheeled Bike Friday for touring and utility rides and love it!

Actually, I almost forgot: I have had a 700c-wheeled bike in the past; it was a hybrid and felt HUGE and ungainly to me, even though the reach to the handlebars was okay. I would never go back to a 700c-wheeled bike.

The way I look at it, 650c-wheeled bikes must be pretty fast because so many triatheletes use them!

Disclaimer - I do ride a 700c bike. HOWEVER, that's because I found a pre-owned one I fell in love with at the right price, I'm a smidge taller (5'4") and I can deal with toe overlap.

That said, I'm still looking lustfully at bike fridays... The Bike Friday folks actually have an interesting answer to the small wheels = slower idea. Take a look at http://www.bikefriday.com/LexiconFull.cfm?ID=53
Basically, their website says up to 16 mph, no difference. 16-33 mph - little difference. Above 33 - there's a difference.

I know that unless riding down a hill, I'm usually in the 16 and under category (or at least relatively close to it), so I'm not at all worried about the performance.

I've ridden with Emily and she dances up hills on her little purple bike (which is BEAUTIFUL)! Believe me, she was going faster than I was on my 700c bike. Methinks it's the engine, not the bike

[emily_in_nc]

Hi CA ~ Thanks for your compliment about my hill-climbing! I'm definitely not a great climber, never claim to be, but I definitely don't feel that my "little wheels" slow me down. In fact, since they're lighter than 700c wheels, they're probably easier for me to haul uphill with! Rotating weight is definitely the most important on a bike, and wheels/tires are rotating weight, and good 650s are lighter than the equivalent 700s; they're just made of less material!

Thanks also for posting the link from the BF site. Great info and will help dispell a lot of myths about small-wheeled bikes beings slow. Yes, my 20"-wheeled Bike Friday is slower than my 650c-wheeled Aegis, but that is because I have fatter tires on it (1.35" vs. 23c), and it's a heavier bike (steel vs. carbon-fiber). All other things being equal, I am sure it would be just as fast.

Now if only the weather would clear up here in NC so we could actually RIDE again, huh?!

I am five foot tall - no inches - and I ride a 700c bike. I have never ridden anything smaller so I cant compare. But I havent had any problems with fit or toe overlap. It is a wsd bike so I am sure that has a lot to do with it. Just my two cents...

[JmcG]

I am 5'1" and I ride 2 Specialized road bikes (44cm) with 700cc wheels (2004 Dolce Elite and the new Ruby Expert) and I also ride a QR tri bike (46cm) which has 650cc wheels. I really prefer the 700cc wheels - mainly because it's a lot easier to find tires that I like available in stores, as well as tube availability. Also, rarely do the 650cc tires or tubes go on sale, whereas it seems you can usually find the 700cc tires and tubes on sale - at least in my experience. As far as handling, etc. - I don't see too much difference - possibly the 650cc makes for a little harsher of a ride? But I'm comparing 2 different types of bikes so it's kind of hard to tell since I've never ridden a 650cc road bike.

Also, I ride my road bike with a group of guys most of the time, and I'm more comfortable knowing that if I flat more times than I have tubes, that I'm covered by one of their spare 700cc tubes!

If the only thing that's stopping you from buying the bike is the wheel size - but you love the bike and it feels great, then I say go for it and buy it. Good luck in your decision!

So True! I'm in Wilmington part time for another few weeks finishing up work and selling the house, and things have definately been soggy here - 13+ inches of rain in less than a week I've managed to get in a couple of night rides (or dark 30 AM rides). I *finally* treated myself to a good headlight and what a difference! My DH has the same one and I kept thinking I had a car behind me - it's that bright!

Of course, I also had my first flat on Blueberry (my blue cannondale) this AM. Seems I ran over a piece of glass. Of course, I flatted just as I was rolling into my neighborhood - 1/10 of a mile from my house. Floor pump here I come (I have a road morph, but prefer my nice floor pump given the choice). Don't jinx yourself! Plus with all of the water on the roads, the bikes now have a nice grime coating. Cleaning time!

I've been trying to get more comfortable with night riding as we're doing a "full moon" ride on the Virginia Creeper trail this weekend. Should be fun!

I truthfully do not know if it was a test or not. From what the guides said, i don't think it was. Two of the three guides were my height and rode the same bike. The only difference I noted in the frame was the slope of the top tube; it was slightly sloped instead of straight across. I crashed doing a tricky manuever crossing a highway and going up a curb cut that was to the left/then having to make a quick right because the bike just felt so different. As I said before, I don't see why people feel that they have to have 700 wheels. We just buy a bunch of tubes at the beginning of the season and stick one in my seat bag. I have been riding for 5 years and I have never had a flat (shhhh!) except for the ones I did myself in the basement for very stupid reasons. But the different tube size should not be the excuse to get a bike that doesn't really fit you. I have increased my speed from an average of about 12 five years ago to about 15, without a very strict training program. So I don't think that the smaller wheels compromise your speed. I can easily maintain 18-19 on the flats on my bike. There's just not a whole lot of flats around here!
So, from what I saw, this was the new configuration for the bike. Maybe you can check the Trek site.

I have a Terry so I'm not afraid of the odd tire size. Seems 650c tires are much easier to find than 24". It would be nice to only have to deal with one tire size... (5'2" 28" inseam and short reach)

I got the idea Trek was dumping the 650c tire. I road a 47cm Pilot and it had 700c wheels.

Other than custom, which is becoming more appealing all the time, who makes road bikes w/ 650 wheels? I'd like to demo one. Cannondale. Litespeed. Others? (Of course. no Cannondales or Litespeeds in my neighborhood.)

Hi SKM, I have an Aegis Swift with 650c wheels (carbon, made in Maine), but they are very hard to find. It's really considered a tri bike, but I don't have aerobars and use it as a club ride/road bike. I wanted to test ride one but could never find a shop in NC that carried them. I ended up finding a leftover 46cm frame/fork combo on Ebay for 2/3 off retail (but it was a 1999 frame I bought in late 2003), and I had my LBS build it up with Campy Chorus and a compact double crankset. A very sweet bike! I could never afford to buy one off the floor, but Ebay made my dream bike possible for me.

Their website sucks, but here you go:

Hey ~ I admire your riding at all in this weather. I've been wimping. I have a severe motivation problem when it's dark gray, misty, damp, and chilly out. I don't have nearly the problem on a bright sunny but chilly day.

We might do the Creeper trail the last weekend of the month. Enjoy your ride!
