I find it increasingly difficult to find 1" thin 27" road tires. I am aware of the Panaracer Pasela's make 25-630 tires, but does anyone know of any other ones out there? Thanks folks.

Google is your friend! This is one hit from 27" bicycle tires...

Yeah I am aware of that site. The only 25-630 tires they offer are the Panaracer's, which I was already aware of. Thanks for the heads up anyway.

Coming from the days of the transition from 27" to 700C as I do, the attraction to change to 700C, for me at least, was that 700C's were available in 25mm - 1". 27" in this profile was something I never saw available. So you might be in for a rough go here.

Good luck!

here are a few more sources --

but, if you're set on finding a 1" tire, pickings are slim.

You are aware, perhaps, that extensive testing (Bicycle Quarterly is one source) has demonstrated that wider tires are both easier riding (more volume to cushion bumps) and faster (more of the tire contacts the road, less bouncing around/losing grip on the road) than skinny? The randonneur riders tend toward the 700-28s, for example.

REI has a few 27" tires, too.

<edited to correct spelling of "losing">

You could always run a set of 27" to 700c adapters

What? There is nothing on the face of the planet that allows you to run 700c tyres on a 27" wheel. Unless you *really* don't like having the ability to remove said tyre to change a flat.

Some other 27" tyres that are decent.

1) Lose is spelt with one o
2) 23/25 is faster than 28's, otherwise everyone doing any sort of pro race would be using 28's

Racers use 23/20's for a reason. Sure if you ride (randoneuring) with 50 extra lbs in panniers and average 20kph, 28's may be faster but who cares at that point what tyre size you're running if you're going that slow?

Spelled, not spelt.

Well, cause & effect is not quite that. The larger tyres at the same pressure actually has the exact same contact-patch area as a smaller tyre. Just that with the larger tyre, there's less sidewall deflection and less sink for lower casing-friction and heat.

A 700x26c tyre @ 100psi would give you faster rolling, more puncture-resistance and more comfortable ride than a 700x18c tyre @ 100psi. Sure, you can pump up the 18c tyre to 140psi to match the rolling-resistance & puncture-resistance, but you sacrifice a lot of cornering-grip and ride-comfort compared to the 26c tyre at lower-pressure.

The Schwalbe 700:28 Marathons on my hybrid are amazing tyres in that they roll extremely fast and offer a pretty decent ride at 100 psi... Schwalbe also makes these for 27 inch wheels and the folks who have bought them from our shop have been very impressed.

We actually have trouble keeping Marathons in stock.

For the ultimate 27 inch tyre I'd say that the Avocet Fasgrip slicks I have on my vintage road bike are as good as they get... they are 633:20 or 27 by 7/8, folding, light, and insanely fast.

They also impart a pretty decent ride even when they are inflated to 120 psi.

Sadly... I don't believe that you will find these fore sale anywhere as Harris Cyclery was the only dealer I know who carried them and they have long since sold out..

What sort of adapter are you talking about?
A switch to 700C wheels, and then something-or-other to get the brakes to line up again?

Or is it something more exotic that you have in mind?

DannoXYZ 

I think he's talking about tyre-adaptors that let you mount 27" tyres onto 700c rims.

slopvehicle

yes. but they're for T I R E S, not the other kind of which I know nothing.

A switch to 700C wheels worked just fine for my '82 Trek. The brakes turned out to be a non-issue, although I still upgraded to some dual-pivot calipers. It could be worth looking into, if the OP isn't trying to keep the bike stock.

DannoXYZ 

Yeah, most brakes have the additional 4mm in the brake-pad slot to make the switch to 700c possible.

Wanderer

I know that Performance has 1" in the 27 line in their forte GT2, with and without kevlar. I saw them there a few months ago when I was buying 1 1/4s.

lamberticus

Awesome. Good to know of another choice for 27" tires in the 1" width. Thanks.

I have used Wal Mart Bell brand 27" tires on four bikes. I likes 'em. Rides fast and smooth enough for me.

You get a point for that one

I would *really* like to see said adaptor.
