Anybody know where to get good 27'' tires? All I've seen in nashbar and performance is 700c except the cheaper models.

BTW, is there any advantage to a kevlar bead to a wire one besides the weight advantage? All i can think of is maybe higher pressure because the kevlar doesn't strech, resulting in less rolling resistance. Any other advantages i dont know about?

Panaracer makes their Pasela in 27". If your local shop orders from QBP from time to time, here are the part numbers and features:

Pasela Tourguard, with a kevlar belt under the rubber to help stop glass
TR2329 27 x 1 1/8 Steel bead 100psi 312 grams
TR2330 27 x 1 1/4 Steel bead 90psi 345 grams

Pasela
TR2306 27 x 1 Steel bead 100psi 254gr
TR2308 27 x 1 1/8 Steel bead 100psi 282gr
TR2309 27 x 1 1/4 Steel bead 90psi 314gr

I have a couple of Pasela Tourguard 700 x 35 with Kevlar beads for my full-touring Cannondale and they seem pretty durable. Besides lower weight, the other advantage of Kevlar beads is foldability. Panaracer isn't offering the Pasela 27" with Kevlar beads, as far as I can see.

I see Continental does offer their Top Touring 2000 in a 27 x 1 1/4. The TT2000 is massively heavy at 550gr per tire in that size. Conti also makes their Sport 1000 (http://www.conti-online.com/generator/www/de/en/continental/bicycle/themes/tires/race/sport_1000/sport_1000_en.html) in 1 1/8 and 1 1/4 sizes, but these are the chintzy non-German-made Contis and I never liked those much.

Aha, just found one other option, the IRC Roadwinner II. They have 1 1/8 and 1 1/4 models with or without Kevlar belts under the tread (all have steel beads, however). These would be good-quality tires like the Paselas.

Omally, i am (to be politically correct) monitarily-impared, and spending-impared as well (I am broke and cheap)

If you are fiscally-challeneged, then avoid Kevlar beads, they are for racing, lightweights and for foldup carry tyres.
Kevlar belts on the other hand make a significant improvement in puncture resistance.

your saying that the only advantage to a kevlar bead is that it folds? BTW, i am not so fiscally challengend that i can't buy two $40 tires. I am, however, not able to plunk down $300 for a pair of wheels. Heck! my parents might even pay for the tires (though its not likely)

Avoid the white 27" Vittoria tires offered by Nashbar. They are sluggish - either heavy or rolling resistance. Not sure which, but they are sluggish. This is surprising considering that they are rated to 120 psi ( and I inflate them to 120).

They are also slippery on wet pavement. Of course, all tires will slip on wet pavement, but these are like plastic on lard.

could that be due to the kevlar 3D compund?

I think it is due to the fact that there is not enough carbon in the tire. I consulted with a friend of mine who is a tire specialist. He is responsible for all the tires for Schneider Transport - the world's biggest trucking company.

"Bill" told me that for optimum tire life and traction, the tire has to have at least 25% carbon. Once you put 25% carbon in the tire, the tire will be black. He told me to stay away from colored tires - or at least make sure that the part that comes in contact with the road is black.

Of course, he told me that AFTER I already had the white Vittoria
tires. :(

By the way, the 3-D compound is a joke. On the maiden voyage, a shard of glass cut right though the tire, though the threading, and into the tube.

The Vittoria 3-d compound is designed for long tread life, not for puncture protection. Any tyre that is designed for wear won't grip worth a d@mn.
