Racing Ralph 36 x 2.25
I recently spliced two old Racing Ralph 26 x 2.25 to make a 36 x 2.25, using this Tutorial.

The Racing ralph is about 800 grams in 36 inch, versus the 2000 grams of the nightrider.
Also changed the tube for a 29 er tube (250 vs 450 grams),
So a total weight saving of 1400 grams on the outside of the wheel.
Needles to say that this action totally transformed the ride.
I hope the tire holds, I have done 3 rides now and it is still OK, fingers crossed.
