Today, I’ve looked for a 700c tyre to get the new rear wheel rolling. The easiest would be a Kojak in 700c size, to match the 26″ Kojak’s at the front, but I had something wide and quick with at least some thread in mind. The first bike shop only offered Marathon Plus and skinny Schwalbe Lugano in 700c, but the second shop had a much wider choice and offered a Conti Cyclocross Speed in 42-622 for a mere €13.
I wasn’t sure if such a wide 700c tyre in the Sprint rear frame would allow a rear fender (you really want a rear fender in a trike to save yourself from crud in your hair), hence I went for a cheap tyre for the first try-out, but it fits rather perfectly.
The seat is set a bit higher and the rear frame inserted all the way into the front frame. The wheel base decreased by 4-5cm and, since I got slightly more weight on the rear wheel, the rear doesn’t like to slip-out slightly when going hard around corners anymore.
That small change in handling was already noticable with the bald 26″ Kojak yesterday and more apparent on my first ride with the finly treaded Conti, today.
More importantly, ‘Nasty’ looks way more balanced with the combination of 26″ at the front and 700c at the rear, than with 3×26″ wheels. 🙂

Rats! Cut the chain too short, I’m afraid, since the bottom bracket boom may need to come out a further 1/2cm.
