"twas teasing you about the ever so popular ATV tire conversion and how the 7 cut and paste rules copied from some other automobile forum don't seem really necessary. It is the spirit of sharing appreciation for one's bike that counts.
I love your post and vote for you even though you didn't adhere to rules 1& 2 but gave a great response to rule #4.
Wow, where do you ride where can you find a 65 degree slope? That is more than a 175% grade, or 1 ft rise for less than approximately every 0.6 ft forward.
Best I've even done on a sustained climb is about mid-80 % grade near top of this 90% slope and that is with 13x55 sprockets and an atv tire.
Perhaps author meant a 65% grade, which equates to a bit more than a 31 degree slope.
Apologies for teasing you ak47man73 about misuse of units. Just that bad stuff can happen when we don't pay attention to the units we use. For example we Americans are very good at screwing up imperial and metric units getting Boo-boos like the Air Canada flight that ran out of fuel halfway between Montreal and Edmonton over Gimli Manitoba in 1983 or the Mars Climate Orbiter that made planetfall rather than orbiting Mars in 1999.
