Well my old Coker was a pain in the ***: weighted like a tank, the rim was almost impossible to true... and frankly I was afraid of the beast. So I decided to change some components. Bought a new Nimbus Rim: Oops the spokes did not fit! so bought some new spokes and learned how to lace the wheel with 4 crosses (Roger I am going to send you a mail about that - I think I have a better idea to explain this to newbies-). Then Didier from our Muni group started to true the wheel: well trueing such a big wheel is a very hard task (even for an expert like Didier) but he succeeded! then I put 140 mm cranks (I can't freemount with 125 and 150 are a bit long). Then new nightRider tire.
Now I am the king of the woods! frankly I like the feeling (I still miss 2 freemounts out of 3 but this is going to change) the wheel is still a bit heavy for my Achille's tendons but it rolls beautifully! Got to train, got to train.... Happiness is a warm Coker !
