I've checked my gearing and it's standard 15/48 so I'm going to order 14/50 tonight.
Currently 60mph is 5,000 revs so I'll let you know how bad/good the new gearing is the not too distant future if you can wait.
I wouldn't you should never have even even or odd odd. you should always have even and odd. if you don't the chain will go over each tooth and never over any others thus causing un even chain wear.
[/quote]that's not really the case, it's sprocket wear that may cause an issue but also unlikely. The idea is that the same roller on the chain will hit the same sprocket teeth every third rotation of the front in the case of 15/45 but in reality it never causes and issue. Certainly chain wear is not influenced by this as it is the side links and pins that wear and cause the stretch not the rollers. The sprocket MAY wear oddly but it's very unlikely unless you don't lubricate the chain at all and use a bolloxed chain.
