Can someone give me the low down on sprokets. Ive seen 9in 50tooth 44 tooth and 36 tooth. whats the general rule
as far as spped compared to the other or any information at all would be great. Im building a bike will be getting the motor soon and want to know the best type of sproket to run. Thanks Tones

Hi Tones!

The 50T sprocket will take you 20-25mph. The 44T sprocket will take you 25-30mph. The 36T speed sprocket will take you 35-40mph. Realize that as you decrease top speed you increase low end power, and vice versa.

Happy will attest to this, all of the top five race participants in Death Race 2007 had 36T speed sprockets. That mountain course went from 3,000 feet to 9,000 feet in a span of 24 miles.

These engines seem to like the higher gearing of the 36T too. They run much smoother and vibrate less. If you are under 200+ lbs and have little or no hills, definitely get the 36T.

I'm using the 36t sprocket, work's well for me.

Thanks a lot thats what ill go with 36T. i live in central california so it works out perfect no hills at all. thanks again Tones

When I get Chain's for my motorcycle's we use a guage size, (#35,#50,#41,#420, ect.) If the chain on our motorized Bike's is 1/2 X 1/8, What gauge size is it? I think it is #35, but I can't seem to find anywhere how to determine that. Does anybody know? Thank's.

I think I found it, should be #43 chain size, If anybody know's this to be wrong please let me know Thank's.

Oh man....I had that info at one time, but to complicate things I think it was a #415.

415 size chains are 1/2" pitch - the distance from center of one pin to the center of the next pin. The rollers are 3/16" wide - inner chain width, and about 7/16" in total width.


I know several sizes will work half assed.

This will help-http://www.azusaeng.com/chain/mcyclchn.html

Yep, #42 is #415.

Doublecheck your measurements before buying anything though.

cool I needed to buy some chain, went to the store and was blasted cause I did not know what size and there guys there were punks about the whole thing si now I know and go to SPARKS cycles on GRANT , like I always do for this stuff, they never give me any shit, have always been super cool and if they are busy and you are patient you will get the help or knwoledge you need to make "it work" just grin and bare it for a few minutes, they can help HIM they will help ME too!

sweet!

Thank's for the link Joe, just what I was looking for Thank You.

alanb, I know those guy's at Spark's, they are all right. Dave W. was co-owner a few year's back dont know if he still is. You can also try: Bearing Belt and Chain Inc. 430 W. 22nd Street 85713 (520)792-1231. They have alway's had what I'm looking for and very helpful.

For you guy's here in Tucson: Just wanted to let you know about Bicas if you dont know already. They have lot's of used bicycle part's very cheap. The people are a little strange, too much of the green stuff I think. But they are very nice.
