    I have a question to ask about sprockets.



    I hear many mention they like the 15/50 sprocket combonation. We all know its easier to change out the rear sprock, so if I drop the rear sprocket to a 49 tooth, and leave the 14 on the front, will I have the same effects and ratio as the 15/50 combo?

    Going up one tooth on the front, is roughly the same as dropping three on the rear, a 47 tooth rear would be closer than a 49

    . This chart shows the different gear ratio's.

    a 15-50 is a 3.37 ratio

    a 14-49 is a 3.50

    a 14-47 is 3.38

    Only a fool would attempt it, and God help me, I am that fool!

    Thanks r80rt!!!!



    I think I'm going to go with the 47 rear, as I'm riding relatively flat ground! I know OMM went with the 47 and he is very happy, and lives in Michigan like I do!



    Thanks again!

    I'm 160 pounds and the 47 tooth on rear seems to be fine. When I got my bike it had a 44 tooth back there and I had a higher top speed in 4th gear than 5th.



    I don't like it when bikes behave like that, so I changed it to have a higher top speed in 5th gear.

    For what it's worth, I tried the 14/47 and it dropped my mpg and trail performance suffered. Trail performance such as creeping in first where there really isn't any trail and going up steep inclines on and off the road. I guess if your trails are mostly flat and open it would be OK or if you are doing only commuting.

    That's one thing I don't really miss is the looooooooooooooooooooooooooooooooooooooooooooooooo ooow 1st gear..... I do 90% on road riding.. And the 10% off road is hard flat trails........... 5MPH first gear was useless to me.... OMM.

    Ok, so let me add another question about going to a 14/47 combo. I'm 220 lbs, so is this going to hurt me in 5th gear! That's a rock solid 220 lbs!

    If you are a serious off road rider 50/50 then keep the 14/50 or even go 14/55. But for our riding in Mich. the 14/47 is the cats whiskers. I go 220lbs. and I still get 80+ mpg. We have land in Da-yooper with miles of two track roads to play on... NO problems at all... Except our sugar sand, but that's in our set-up.... We are running the street front tire. But even with the stock front tire I hated sand... Good luck with your choice. OMM.
