Jack Brown BLUE

This 700C tire was developed for riders (like us) who want a fast, light, high-volume and cushy tire, and at the time of its conception and birth, I'm pretty sure it was the only tire to fill that slot. Jack is about 33.333333mm in diameter, so it won't fit most road bikes with carbon forks, but that's more a fault of the fork than the tire. It will fit any of our road bikes built since 1998, and many of the ones before that. ; and of course any cyclo-cross, touring or tandem frame out there--unless you happen to find one with shamefully tight clearance.

(Jack Brown's radius is 350mm, so you need about 354mm between axle and metal. This is an easy measurement to take, but requires x amount of precision and care.)

The GREEN version is like a plumper Roll-y Pol-y, in that it has a normal casing and tread, with no beefening-up features (thicker casing, kevlar belt, extra rubber) that would add weight. It is the one we recommend for pure road riding.

The BLUE version is the same volume, but has an extra strong casing, kevlar belt, and thicker tread, so it weighs more. We recommend the BLUE for trails, commuting, tandems, or just all-around riding if you aren't weight-obsessed. Both are made for us by Panaracer in Japan. There's nothing to say you can't run a blue in back and a green in front (or vice versa, for that matter). Mark here rides the GREENS even on trails, but he's 145lbs and knows how to avoid the sharp rocks and deep holes.

(The second photo shows the inside casing, and you can see the belt in Jack Brown BLUE. It's not super obvious, but it's there.)

Take a look at the Schwalbe Marathon Supreme if you're interested in something a bit fatter. And the Ruffy Tuffy or Rolly Poly if you want something a little skinnier.

Just put a set on... March 31, 2014
Reviewer: Steven Schwartz from Milwaukee, WI United States  
And I'm not sure how or why, but they transformed the ride on a bike I've been trying to dial in for quite some time. Really look forward to piling on some miles!

Best tire I've ever rolled! March 3, 2014
Reviewer: Nicholas Bull from Presque isle, ME United States  
First off, love the Rivendell mindset. So with that said, these tires are the bees knees!! I have ridden these suckers in all kinds of weather (-30F being the couldest), over many different surfaces, and for about 8 to 10k miles with only 1 flat!!!! Use mine all the time, and couldn't be happier;-)

Thanks for all the smooth miles,
Nick

Best compromise between light/fast & no flats January 30, 2014
Reviewer: Bruce C from Seattle, WA United States  
I used to roll on the Jack Brown Greens which are I loved, and are more supple and flexible than the Blues.  However, as a bigger, heavier rider I would get flats, usually from glass shards working their way in over time. I have not had any problems with these... only one flat in about 7k miles (from a wire coming in from the side).  While they don't feel quite as light and zippy as the JB Greens, that kevlar belt makes a huge difference.

The previous reviewer is correct that these are harder to get on, however, chances are you will not have to get them off again.  I didn't have quite the mounting problems that he did, but don't expect to get them on/off with your bare hands.  You might need all three levers to finish the job.
If your frame doesn’t give you a lot of clearance these tires may give you the most air possible.  I can fit these on my Rambouillet with VO 45mm fenders (with a filed-down fork bolt).

Great tires, once you get them on October 29, 2012
Reviewer: Steven Thornton from Seattle, WA United States  
I love these tires. I think they're the best tires in the universe. The only problem I had is mounting the suckers; they are EXTREMELY TIGHT, and I had to use my levers, and I pinch-flatted two tubes getting one tire on. Ugh.

But then, after they're on, you won't have to change them for many years. Don't get me wrong. I gave 'em five stars.
