As most of my bikes (now) are 27" my tires have been 1 1/8 (28) or 1 1/4 (32).

Going from 28 to 32 was a pretty big difference to me. That mitigated a lot of bumps to me.

A while ago I had a set of 1 3/8" (37). Riding those tires was like riding on a poofy cloud made out of cotton candy and Cottonelle toilet paper.

Since then I was searching for a set of non-knobby, decent quality 27x1 3/8" tires. I found them in the Loose Screws Swift Tire Sand Canyon. I'm reserving judgment on them until I get some decent miles in some different conditions with them. Right now, for the pavement I've ridden them on- there doesn't seem to be a whole lot of difference between the 1 1/4 and the 1 3/8, not like the old Specialized 1 3/8 tires and the modern Pasela 1 1/4. So I'm thinking there may be a big difference in either how tires were made 25 years ago and now, or the Sand Canyons are designed to be less supple than the Specialized Expedition OR the age of the tires made them more cushy.

I'm very happy to have found a 27" alternative or accessory to the Pasela.

Created my own last Fall from a dump find '86 Trek 830 Antelope frameset and Maxxis Hookworm 26 X 2.5 tires (about 63mm). I must admit it is fun to ride at about 25-30 psi. Is it the fat, mostly smooth tires? I don't know. Could be. :innocent:

I was considering those HOOKWORM's but they would not fit in the fenders! Cool looking tires though! Kind of a mini phat bike!

Nice! In the ballpark but not quite the same. The Ravn is designed to be a light weight-ish/front loading/light-gauge tubed, ATB/ road bike. I have done a few mtb drop bar conversions but never really liked them. The frames are pretty dead on the road and the handling always felt a bit off. I don't have the $$ to buy a new bike but would be interested in trying the Rawland.

Maybe Jan's been looking at too many pics of bikes like this lately??.....:rolleyes::D

Oi!, one can put his whole family between the front wheel's spokes for a nice hamster style bike trip!

I ride my drop-bar conversion a bunch, but if I could snap my fingers and steepen the head tube angle from 71° to 73°, I think I'd really love it. The weight of the bike isn't bad, but the steering is heavy with all that trail and wheel flop. On the other hand, I wonder if it would do worse in snow and mud with more weight over the front wheel...

Bet the Ravn would be a sweet ride. :)

Cool bike but how is that really any different than a used 80's vintage MTB? Other than 1 1/8 headset it's not.

That is a really nice bike.

My experience doesn't jive with [MENTION=73614]rhm[/MENTION] 's on the Big Apples. I wonder if s/he was riding the base model Big Apple? The performance version weighs 200 grams less than the base model and is made out of a much more supple casing. I've really enjoyed mine in the 26 x 2.35 size, inflated to ~30-35psi. They are as supple as my Paselas, roll quite fast, and absorb all the nastiness of urban riding.

Specs on the difference between models: Big Apple HS 430 | Schwalbe North America

My wife has a different opinion of Schwalbe Fat Franks.

She rides her old Stumpjumper everywhere and she runs them usually at 75% of max pressure. She drops pressure down at the river in sand and muck.

They work well on our cruddy St. Paul streets, are super strong on our limestone trails, handle a fair amount of sand down at the river bottoms and to top if it off, she often extols how plush they are even after a 50 miler.

I doubt that she would want to tour on them, but they are great for 90% of her local rides.

Yes, I'm sure I was in the most base model Big Apple. I'm glad to hear there are better.

I would be very interested to hear your opinion of the Sand Canyon. Most of my bikes are 27' as well and I have been seriously considering a set of these tires. If you get a chance, could you tell me how wide they measure and what rims you have them mounted on. If.you don't mind, a picture of the tire mounted on a rim would also be greatly appreciated. It is hard to make out the tread pattern on their website when they are folded up. Thank you.

Huge difference in geometry compared to most 80's MTBs.

I wasn't planning anymore bike purchases this year, but this may change my mind. I ride mostly off road anyway and this looks like just the ticket.

I was also considering one of these Elephants down the road, but I like the tire choice better on the Rawlands.

Still, the Elephant is a pretty good value at $1,285 for the stock frameset, $1,700 for a custom.

Dang, let's just ride fat bikes on that next Century ride.

This is just a tactic to subvert the 26" tired mtb. that is taking over the 650b.

Or, just taking a hint from, innovate or die.

We are doing 107 miles of a 250 mile trip this summer on gravel.

Hopefully it's all hard packed as I'm only running 700x30s.

I really see no point in going super wide if you are on pavement 100% of the time, but soft, fresh or wet gravel can change everything rather quickly.

Then I went a nice wide, plush tire.

Something I can drop the air pressure on and float over rocks, sand, muck etc.

Yes sir.

Here's the deal though.

I got sick of riding on bad city streets and fighting traffic and found the country roads here were just a new reason to ride for hours without dealing with that stuff.

I just needed bikes that could handle a little more tire and I've been happy ever since I switched.

I agree that wider tires are better for mixed surfaces, especially with a heavy load or a heavy rider (I'm #225 ).

I ride a lot of gravel roads and paths which can have a loose surface where they've been recently re-done, as well as sandy spots, potholes, and washboard. My 650 x 38 Pari-Moto tires can make it, but still dig in dangerously in spots. My 26 x 60 Super Moto tires have a lot more float and just fly over all but the roughest loose gravel.

I also agree that you have to choose the correct Schwalbe tires. They make many variants of each tire design, varying in size, construction, bead, and puncture proofing. Their high-end, lightweight variants are legit race quality tires.

The Schwalbe Super Moto is already everything that Jan's new fat tires are trying to be. Fat, and fast.

They're expensive and hard to find in the states, though. I order them by the handful for $34 from Germany.

And yes, a rigid 26er mtb is can be roughly the same as the Ravn, but with weird geometry quirks. Or chainstay U-brakes.

Honestly, my experience with my converted '88 Schwinn KOM makes a modern bike like the Ravn more attractive. Simply because it is even more dialed-in for the type of riding I do.

But I would definitely prefer a bike like the Elephant NFE (or even Jones Plus) because of the disc brakes.

The Jones Plus does look cool, for sure.

Jones Bikes ? Jones Plus ? 29+ like never before . . . .

I also like the Niner ROS 9

and the Surly ECR for that matter

For that kind of riding, my Centurion with 27x1.25's would do. Back in the 70's we rode in anything with our 10-speed bikes.

I forgot:
my KOM with Super Moto on front (too wide for the rear U-brake)
http://bikeforums.net/attachment.php...hmentid=457345
and where to get them cheap

A lot of Schwinns were running 26x2.125's back in the 50's, some with smoother tread patterns.

They were heavy but they were often ideal, overall, for mixed riding.

Then the "lightweight" craze came along, and 27x1-1/4" sort of took over, equivalent to 700x32. Users noted they were far more fragile.

This continued until the de-rigueur tires and rims of road bikes were often narrower than 20mm wide, needing a minimum of perhaps 120psi for an average-sized rider.
Many of these bikes, as with the previous decade's tubular-shod racers, ended up hanging high up in garages with a flat tire, never to be fixed since this might be considered futile.

So we've come quite a ways away from that sad scenario. I fitted 25mm "Hard Case" tires to a customer's 1986 "Dave Scott Ironman" the other day after 28mm Specialized tires did not fit under the rear brake arch.

If this trend continues, I fully expect to hear from him asking me to change the design of my tire wipers a bit.
Made mostly for 22 to 32 mm tires. He's sold over 300 pairs of them in their current configuration, so I'll try to adapt. :thumb:

I'm running 26 x 2.0 marathon supreme touring tires on my drop bar conversion mtb. The weight isn't bad for a big tire with good puncture resistance (565 grams). Plus they ride great.
