one piece crankarm width

[freddyfingaz]

What's the widest length of ONE PIECE crankarm that is crossing the BB available?

I dont' know exact widths but a few options. Look for at 1950's or older Schwinn balloon/Heavyweight crank. or any bike that has a multi-speed front (Walmart bikes)

 

[freddyfingaz]

They don't make multiple speeds on bmx bikes?

I'm looking for fat arm or cool shaped. I have several multiple speed mountain crankarms. Too skinny for my OCC pedals.

Do you want fatter arms or longer axle/threaded portion?

Both.

Better to be functional first.

This look awesome but not sure how long axle is.

The reason why I'm looking for this because I'm attempting to put chain guard on multiple speeds sprocket. I need the one has more clearances.

Where is your derailer going to fit? Derailers and chainguards don't always mix.

On seat tube above sprocket. I have 18 speeds cassette sprocket. It's close fit but still need more clearance between arm and sprocket where the guard goes in between of them. For derailer, I might able to pull it off set it low enough where eliminator guard can cover it. Lemme get the pic. But the three sprocket might be too thick. I'm thinking trim edge slightly.

If it can't be done. I rather not harm this nice chain guard.

Is there more ways to mount front derailleurs? I thought all front derailleurs are same.

Old derailer probably wont' fit under there. Some of the new derailers with low clamps might work.

18 gears is alot on a 24" bike. My everyday commuter has 14. And the bike I took on a 170 mile trip only has nine. :mrgreen:

Lol yea. I wanted lowest teeth sprocket for more torque and 52 teeth for top speed. 6 cassette gear hub is only rear wheel I have that is working. Rest of them are seized
