Hi there, I am a newbie, can someone please educate me the term "Clincher" and "tube"? When I check out bike wheel makers, they always have weight difference in these 2 set ups. Thanks for your help.

In regards to your wheel question,
Clinchers have separate tires and tubes, got a flat just change the tube.
Tubulars or "sewups" have the tube sewn into the tire, its all one piece and is glued to the rim.

Thanks for your reply.
How can I tell what I have now? Is there anything written / stamped on the tire?

If you let the air out of the tire and can separate the tire from the wheel, you have a clincher. If it is glued on, you have a tubular. I would say at least %80 of the tires out there today are clinchers.

Thanks K_dogg, you're right, I have clinchers.
I have been thinking about getting a set of lighter wheels, I have considered carbon composite wheels but was told by the bike shop that they're not very durable and should only be used at races. So, I have rejected the idea of carbon compo wheels. Can anyone give me a good suggestion of wheels? Or should I ask, is there any wheels on the market that i should definately avoid?
I am looking for 650 wheels.
For both training and race.
I am doing Du and Tri only for fun. Competitive is secondary.
I want lighter wheels - Mainly for comfort, second for speed.
I hope i have given enough info for you to help me.
Thanks again.

That question opens up a whole can of worms, and you may get a list of posts here a mile long... But I would reccomend going with a Mavic rim with a Dura Ace or Ultegra Hub. This is currently as close to "industry standard" as you can get. Where you order them can also vary your price, but I would reccomend looking at excelsports.com. This is a reputable shop and has some good deals. Look at their cirrus wheelset, and then call them because I don't know if they make them in 650. Also you might want to look at something built with a CPX33 rim. Not the lightest or the Aero-est, but a good durable, combination of both. I would also reccomend going to your local bike shop and paying a little more and benefitting from their advice. Also if you have some cash, but not a lot, I would also reccomend talking to Dave Thomas, info at speeddream.com...

K_dogg makes a good suggestion with the CXP33 Mavic rims. I have used these for everyday riding and are virtually bomb-proof.
Have hit some pot holes pretty hard, blown the tires but not even a chip out of the rims and they've stayed true in the 2 years I've had them.

This is one of those really depressing questions. I know it may seem important to you, but you are misguided.
Let's start with a simple concept: training is training and racing is racing. If you currently have a servicable pair of wheels that will carry you down the road, you already have training wheels. If your goal is to go fast when you race train on the wheels you have and buy a good pair of aero racing wheels.
That is if your real goal is to go fast. What always seems t be hiding behind these questions is a desire to look cool while training and to score points because your bike looks faster than the other guy's.
The proper technical term for this condition is "posing". Nothing wrong with that. Bike shops and mail order houses make a ton of money from posers and that helps the rest of us. But if you are serious about how you race and aim to improve do two things:
1) train on the crummy wheels (they probably are really nice) you already have.
2) buy some really aero race wheels and use them ONLY FOR RACING

Thank you everyone for your advice. And I agree with that "posing" part. However, I am almost 40 and am way over that "posing" stage. Mine is mainly "lazy" and "let the $ do the work" kind of attitude.
Went to a bike shop and talked to the owner and some pros. They all agree that regardless of your physical condition or skill, a set of lighter (more aero) wheel will make noticible difference on peddling effort. I guess this is my main reason for a set of lighter / durable / train / race / wheel. Maybe there is no such thing but it wouldn't hurt asking all of you, right?
cheers.

first off, this Kiwinick dude seems to have alot to say on every subject. "Kiwi", what do you care if some dope with more money than brains goes and spends a wad on "race wheels" to ride everyday to look cool. You can ride all you want on a fancy-assed bike, but it don't matter til you bring it to the line. Then you just look like an idiot as you try to lift your belly over the top tube to "race".
haaaaaaaa Hard
