Couls someone define the difference between these?

Sew-ups/tubulars are a tire & tube combo that is stiched together and requires glue to be mounted on the rim.

Advantages = better ride and (slightly) lower rotational weight.

Disadvantages = Big pain to change the tires, higher overall weight (you need to carry a spare tire instead of a patch kit or tube) & potential for catastrophic failure if you don't glue the tire correctly.

A clincher is a "normal" bike tire with a separate inner tube. Best for 99.9999% of riders IMHO.

Just a few comments: I'm guessing that you don't actually ride tubulars. It's actually easier to change tires and deal with flats if you're using tubulars. Just rip off the old tire, slap on the spare, and inflate. If you're racing (which is when most people use tubulars, this doesn't matter but at the same time you don't have to carry a spare tire).

In my opinion, aside from slightly lower weight the biggest differences b/w clinchers and tubulars are flats and safety. Most people find that tubulars are less prone to flatting due to their construction. Along that same line, tubulars deflate rather slowly instead of all at once like clinchers. Also you can ride on a flat tubular if you have to (not gonna happen with clinchers). All of this means that if you are hauling, you stand a chance of staying upright with tubulars when you would be on the pavement with clinchers. Additionally, I've never actually seen or even heard of anybody rolling a tubular (except for that friend of a friend's cousin's brother).

Actually, I've been riding with tubulars on and off for 7 years. I agree with most of what you say. However, the prospect of replacing one in a race with sweaty hands while cursing and shaking and relying on dried out glue & air pressure to hold the tire on the rim under potential severe cornering... I need to meditate...

What kind of racing are you doing? I've never changed a tire in a race. I don't carry the equipment to do it. That's what wheeltrucks and wheelpits are for.

I've been lucky enough not to get a Fl@t with my tubbies. When I've replaced tires, due to wear, it has been far from what you describe. Let see...ten minutes of screaming and cursing in my basement. Wife comes down to make sure everything is OK. My thumbs are raw and dislocated from trying to pry the tire off.

No flames intended but IMO, if I could take my tires off that easy I'd be taking the corners slow.

Although there is clear advocacy for tubs in this one

I've been running a tub on the front and a clincher on the rear for a while (just the wheels I had) I've had 1/10th the punctures in the front and it is noticably lighter and rides better. Bit of a silly arrangement though, I have to admit.

The tubular on the front is not necessarily silly. I ride with a 19mm Continental Comp GP on the front for aerodynamics. The aerodynamic shape of a tubular tire on a rim is somewhat different than a clincher and combined with the lighter weight will work well. The weight advantage of a tubular is not just in the tire but in the rim too since it doesn't have the hooked area to hold the tire sidewall in place.
