touring tires for folders
 
I just came back from a short trip in Oregon with about 25lbs of stuff on the bikefriday. If anyone wants a comfy touring combo that's low rolling resistance try out the combo of a 2.0 Big Apple in the front and a 1.6 Marathon Supreme in the back. Pumped up the tires don't have much rolling resistance but the fatter Apple is great for hitting small rocks and bumps on high speed descents.
9spd Capreo with 44t chainring provided sufficient range of gears.

Are you able to use the same tube for both tires?

funny you should ask, yep, both tubes were the same size although the one for the 2.0 Apple was undersized. I think the tube has stamped on it 1.25-1.75(vague memory, could be wrong) On hwy 140 there's a ten miles 5% down grade that I did in about 20minutes. There were enough bits of rock and shifts in asphalt level on the newly paved road that I prefered the bigger tire in front as it made the transitions securely where new pavement was 1/2" higher than old pavement,,,where I had to ride when passed by cars. On the other hand the ride in the other direction took about 2 1/2hrs! When you're middle aged and out of shape gravity really sucks going uphill.

One thing that's always bugged me (as a former bike shop mechanic/owner) are new bikes sent out with over tight bearings. The BF are good designs but the NWT I ordered came with a JoyTech front hub with rubber seals. The rubber seals squeak at low speed "wth is that noise?" and the bearings tight. Front bearings should be very slightly loose so that when the QR is compressed the few thousands of an inch looseness is taken up by the compressed axle. Anywho, that's why I switched front wheels as I didn't have cone wrenches to adjust it and the Shimano hub was adjusted correctly out of the factory, riding with a Schraeder in the front and presta in the rear. The tube in the 2.0 is the one BF sent with the Llama (I got two BF, one the NWT with fat fork for me set up with drop bars and a Llama for the gf with flat bars).

I didn't check pressures accurately except extrapolating from a schrader pencil gauge that didn't go above 50psi,,the front tire was somewhere around 60psi and the rear higher as I pumped it until it made a higher sounding note when struck, I'm guessing it was around 75psi. Over a weeks time the front didn't lose enough air to be noticable although I did give it a few extra pumps for good measure.

That is what I recall ... that most tubes for 1.5" fall short of 2.0" width of the Big Apple. But I just did a web search and saw these ...

Although it occured to me that it might be a misprint, so I checked the Schwalbe website and sure enough, they have a 1.5 - 2.5" presta and schaeder value tubes.
