Crank forward number 3 revision A



Crank forward number 3 was a very comfortable cruiser bike but the wheelbase, at 53", was a bit long and the front end a bit heavy for off roading and curb jumping. I decided to copy the geometry of the back portion of my first CF bike and drop 2" from the rear triangle length giving a new wheelbase of 51".

The result was very satifactory and the bike handles very nicely. I can stand up on it pretty good for hill climbing. Note the rear brake yoke cable routing due to lack of clearance behind seat post.

Crank Forward Number 3 painted



Got the painting done on CF3. I retained the original paint on the fork and most of the downtube in order to preserve some of the Schwinn decals and the original paint is much more durable than the Duplicolor touchup I used on the rest.






Here is detail on the seatpost. Note I borrowed the idea from Rans for marking the inseam measurements.
This bike is very smooth riding and quite comfortable. With the 53 inch wheelbase it seems slower handling the my first crank forward bike that has a 50 inch wheelbase but I doubt that there is much difference in speed as weight and tire styles are similar on the two.
