Turning a 21 gear mtb into a 7 gear.

[littletinman]

Hi all,

I think this is the right area to post this. My main ride is a motorized Pacifca Scorpio. It has a shamino 21 speed shifter gear thingy (for lack of better word).

I want to basically free up handlebar space and go to only one gear shifter. The shifters are thumb shifters.

Anyone have any suggestions on how to approach this?

is it 3 gears on the pedals and 7 in back? if so just take the shifter off and put the chain on which gear you wan tit to stay on you can even put a jump stop to stop it from jumping to the smaller gear. if its a all in one hub then im not to sure on that

Shift into the middle chainring, then remove the grips possibly the brake lever and the shifter on the left handlebar. Take out the Bowden cable, set aside the items. Then reattach the brake lever and grip.

Did anyone ever find out how to do this with a one sprocket on crank?I'm thinking about doing this with a one wider crank arm set crank with one sprocket instead of three sprocket.I need the clearance for centrifugal clutch.

I did! I simply removed the little aligning thingy that attached to the center frame post. IT was super simple.

Here's a picture of the element i'm referring to.

So all you do is remove the front derailleur.

Here's an anatomy of a bicycle that will help identify the parts of a bicycle, so hopefully in the future, parts won't be referred to as "thingy". Lets not get human anatomy and bicycle anatomy mixed
