|Clinchers vs. Tubulars?||molampp|

|Been riding 4 months, bought a cheap starter, but had rolf vectors on it. Want to upgrade to Trek 5200, but then I got into a discussion at the shop about the wheelset. 5200 comes with rolf comps, I was looking at the pros and the sestieres. Each can either be clinchers? or tubulars. Years ago we only had sew ups or tubes. Whats with clinchers? Sounds like a stupid question, but that's what I get for staying away from the sport for 10 years. Thanks|

|... clinchers, like your auto tires, use the bead of the tire and the hook lip of the rim to secure said pressurized tire (with a tube inside) to the rim... tubulars are sew ups (tube sewn inside a casing) which are glued to tubular rims (no hook lip)... in general, they are not interchangable (Tufo makes a tubular tire with a bead so that it's essentially a tubular clincher and is used on a clincher rim).
Until recently, most pros and elite amature riders would have opted for tubulars (mainly for their ride characteristics, lower rolling resistance, light weight, and safety in case of a blowout) but high end modern clinchers rival tubulars in most respects (and don't forget Tufo's option).
The biggest drawback to tubulars are a rather time consuming glueup proceedure and lack of an easy roadside repair in case of a severe puncture (many tubular riders will carry a spare casing instead of trying to repair the damage... at least on the road). Some will even abandon a damaged tubular once they get home rather than attempt the repair themselves... (tubulars are generally more puncture resistent than a comparable clincher).
I only use tubulars for TT's but I know of a few local riders who regularily commute or tour on them. I guess it all depends on your priorities.
If I only had a single principle wheelset... it would probably be a clincher... if I had a third or fourth set... I'd experiment a bit...
Be the bike.

good advice from akirasho.
it really depends. clinchers have come a long way and the gap is closing.
i still ride tubulars as my only set of wheels (in NYC). but im pretty carefull and always inspect my tires after a ride. i feel i am less prone to flats compared to my riding pals. i enjoy the ride a lot and the roll i get with 170 psi is something i have come to enjoy.
on the rare occasion i have a flat i carry a chaepie spare and some glue and strip the flat and replace it in little time. i have a guy who does a good job of repairing the flat and i replace my cheapie spare with it a.s.a.p.(i usually just ride home after a flat) . but as i said its pretty rare and easy as my rides are usually just laps of central park.
have heard of tufo's product that is said to seal all holes as soon as they happen. needs to be sprayed into the tire but still have questions as to what this does to the inner tube and valve longterm.
tubulars are a great thing but not for everyone. dont waste your time with cheap tubulars s they are inferior in quality and give away any advantage with regards to weight. they will cost you more in the long term.
the advantage is still there with regards to lower rim and tire weight. and of course circumferential weight is more important than hub weight. sprinting and climbing are always a delight but if you ride mainly flat roads at a steady pace the advantage starts to wane a little.
i have a rolf pro front wheel and have nothing but good things to say about it. i keep thinking of sticking a nice chrome fork in my wall and attaching the rolf to in homage to duchamp. a fast wheel is a thing of beauty.
my opinion is that too many people focus on groupsets where i feel that at least 1/3 of the value of your bike should be spent on the wheels. there is nothing like a good set of wheels.
if in doubt about maintenace there are a few clincher tires sneaking around at less than 200 grams that you can enjoy with less to worry or think about although they wont last as long as say axial pro's or conti gp 3000's.
whichever way you go if you look after them they will rpove enjoyable.

|Another example of a good lightweight clincher is the veloflex Pave. All of the ones I've weighed have been 175gms. I get about 1000 miles on the back with them. They are also pretty cheap if you get them over the net.
good rides JohnG

|I'd only use tubs if you race a lot...and then you better like to sew and glue. not worth the hassle for us mere mortals who maintain our own stuff IMHO.|

|I've been riding tubulars exclusively for the last 16 years. My current set up is Vittoria CX/CG tubulars (pumped up to 140 psi) on Campy Barcelona rims w/campy record hubs. This past weekend I finally traded wheels with someone so I could get a taste of what modern clinchers feel like. I tried some Continental gp 3000's mounted on Mavic Open Pro rims and Campy chorus hubs.
The ride of the clinchers felt squishier and at the same time, rougher. I could feel the tread of the Conti tires through the handlebars. During hard cornering, I could feel the flex in the tire rubber of the clinchers. The clincher wheels were also heavier, making for slower rotation on the wheel and had significantly more rolling resistance. My riding mate has had over a dozen flats with his clinchers in the last year. I have had two flats with my tubulars in the last year and I've put on more miles than my friend. On my last set of tubulars my front tire lasted 800 miles and my rear tire, 1300 miles. The rear punctured only after a tiny rock made its way into the almost completely worn tread. I think I will stick to my tubulars.

|It is obvious from reading some of the posts in this discussion that you guys must ride on some very good roads. I live and race in New Zealand and I never put more than 110psi in my tires. New Zealand has some of the worst sealed chip roads in the world. This is because of the materials used(volcanic chip). Now back to the debate.......I use both tubulars and Hp's. I primarily use Hp's, easiler to fix if you are out training, and cheaper just throw in a new tube. Racing however I only use tubulars, as mentioned hp's have come along way in the last few years but they are still not as good as tubulars. I don't think they ever will be because of their design limitations. It is the tire rim interface that holds them back. If you are wanting to train on tub's then go conti sprinter 250's I have seen these ridden down to the casing and still keep going. Racing tub's vittoria/ veloflex/clement. You can't go past these they are very lively the drawback, cut/wear quickly. Hp's training hutchinson excel 28mm, these are bulletproof. hp's racing veloflex/vittoria same reason as above. Hope this helps.|| |
