I purchased a used 19% reduction pulley from a fellow NAM member and they thought it was an Alta, after doing some research on the looks of it I am almost 100% sure its a Helix considering there is no name on it as well as it has 6 set screws unlike the Alta having 4 but I am concerned whether or not it is actually 19% or not, can somebody give me the dimensions for the 19% pulley so I can check it?

 

2.07'' will give you a 19.8% reduction. This is measured top of rib to top of rib. More info can be found in the sticky "let's dispel some myths". Hope that helps

 

Thanks

 

Kendel, you beat me to what I was gonna do! lol hope everything works out!

 

Yeah I got the dimensions so now I have to measure it when I get home, I will let you know!

 

Alright.
