awww...I don't ever get to watch SNL anymore...

(not that anyone who watched it with miller, spade, farley, hartman and the rest of the cursed thinks it's still good...)

I stopped watching about in '91, and only know the Sprockets because I have a German boss and a friend sent me captures.   :lol:

thank ypu dgyver. that iss exactly what i was looking for. looking at that i might go as short as 15 / 47, but i'm not quite sure yet, i do want sorter gearing, but i don't want to be shifting constantly, maybe just the 15 / 42. i dunno.

once again thanks for that link.

Quote from: Church6360hmmm... trying to find out how much impact on mph at a given rpm a change of teeth makes.

I may be a bit late to give this, but just in case there's still interest in the effects of sprocket changes, have a peek through my Adding a Tooth -- Going Up to a 17T Front Sprocket thread.  

I did a practical comparison of Speed & RPM between the stock 16T and my updated 17T.  Nonetheless, I like the link to the Go Faster Tools that
dgyver pointed out.  

good thread, yeah, if an a change of 5.86% made a difference of about 400 rpm in a given gear at a constant speed then a change of 13% would be about 900ish rpm difference.

and going 15/47 would cause a change of 22.2% from stock.
which would cause a change of 1500 ish rpms in a given gear at a constant speed. (if my math is correct)

hmmmmm... i need to go ride my bike and then ask myself if i'd really be comfortable with that kind of gearing.

There's got to be someone on this board that's done this.  

Kinda radical in my view -- you should be able to skip half the gears when shifting and not have the bike complain.  :dunno:

yeah, i might as well give it a shot, i think when i get around to it i may order a few different sprockets, like a 15 and a 17 for the front, and a 47 for the rear. the front ones are cheaper, and that way i can play around with the ratio's a bit.

if 15/47 is too short i can switch to 17/47 which would be a more manageable 12% shorter than stock.

Sprockets???    Undt now ve dance......
